Description

[Technical field]

[0001] The present invention relates to a packaging form for a floor surface adsorption sheet, a packaging method for a floor surface adsorption sheet, and a method for reusing a floor surface adsorption sheet. [Background technology]

[0002] Conventionally, sheets have been used that are attached to floors, etc. As sheets that are attached to floors, etc., the following exemplary techniques have been disclosed.

[0003] Patent Document 1 describes a floor decorative material comprising a thermoplastic resin substrate containing a polyolefin resin as a main component, a picture pattern layer, a transparent thermoplastic resin layer, and a surface protective layer, at least in this order.

[0004] Patent Document 2 describes a building in which a first decorative sheet is attached to a portion of at least one surface of a floor or the like, and a second decorative sheet is attached to the remaining portions. In the building described in Patent Document 2, the first decorative sheet comprises a first decorative layer and an adhesive layer laminated on the back surface of the first decorative layer, with a plurality of recessed shapes formed on both sides of the adhesive layer, and the second decorative sheet comprises a second decorative layer and an adhesive layer applied to the back surface of the second decorative layer.

[Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2009-108616 A [Patent Document 2] Patent Publication No. 2022-049913 [Patent Document 3] International Publication No. 2018 / 051984 Summary of the Invention [Problem to be solved by the invention]

[0007] In recent years, sheets with patterns have come to be used on road surfaces and floor surfaces to display various patterns such as advertisements and guide signs. One example of such a sheet is a floor adhesive sheet used in an indoor environment. Floor adhesive sheets used in indoor environments are used by being attached to floor surfaces of, for example, stores, gymnasiums, and community centers. Floor adhesive sheets used by being attached to floor surfaces may be peeled off from the floor surface after use and reused repeatedly. When a floor adhesive sheet is used repeatedly, the floor adhesive sheet is stored until it is reused.

[0008] When the floor surface adhesive sheet is stored, there is also a method of storing the floor surface adhesive sheet in a flat plate form. When the floor surface adhesive sheet is used in an indoor environment with a large floor area, such as a gymnasium, the dimensions of the floor surface adhesive sheet may be large. When a large-sized floor surface adhesive sheet is stored in a flat plate form, the securing of a storage space, etc. must be considered. In addition, when a floor surface adhesive sheet stored in a flat plate form is moved, the transportation method, etc. must also be considered. For this reason, when the floor surface adhesive sheet is stored, it may be preferable to store the floor surface adhesive sheet in a roll form in terms of the storage space and transportation method, etc.

[0009] When the floor surface adsorption sheet is packed and stored in a rolled form, for example, a paper interleaf is used as the packing sheet, the floor surface adsorption sheet is placed on the interleaf, and the floor surface adsorption sheet is rolled up with the interleaf in between, to form a rolled form. Since the interleaf is made of paper, it has the disadvantages of being easily torn and easily sticking to the adsorption surface of the adsorption sheet. It is also possible to use a release paper as the packing sheet. The floor surface adsorption sheet is placed on the release paper so that the release surface of the release paper faces the adsorption surface of the floor surface adsorption sheet, and the floor surface adsorption sheet is rolled up with the release paper in between, to form a rolled form. In this case, since the release surface of the release paper has high smoothness, the release surface of the release sheet and the adsorption surface of the floor surface adsorption sheet are easily stuck to each other. Therefore, when the rolled product is unwound and the floor surface adsorption sheet is reused, it is difficult to peel the floor surface adsorption sheet from the release sheet. In addition, since the release surface of the release sheet and the adsorption surface of the adsorption sheet tend to stick to each other, when the floor adsorption sheet is rolled up with the release paper in between, this may cause wrinkles in the floor adsorption sheet. Furthermore, if the floor adsorption sheet meanders when it is rolled up with the release paper in between, it becomes difficult to correct the meandering, and the sheet is likely to become misaligned when rolled. For this reason, further improvements are needed when the floor adsorption sheet is packed and stored in a roll shape.

[0010] An object of the present invention is to provide a packaging form and a packaging method for a floor surface adhesive sheet which, when packaged and stored in rolled form, prevents the occurrence of wrinkles in the floor surface adhesive sheet, has good peelability from the packaging sheet, and prevents the occurrence of roll misalignment, as well as a method for reusing a floor surface adhesive sheet stored in said packaging form and packaging method.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] [Packaging form] A first aspect of the present invention is a packaging form of a floor surface adsorption sheet. The packaging form of the floor surface adsorption sheet according to the first aspect of the present invention includes a long packaging sheet having a first packaging sheet surface and a second packaging sheet surface that is the surface opposite to the first packaging sheet surface and has unevenness on the first packaging sheet surface and the second packaging sheet surface, a floor surface adsorption sheet in which an adsorption layer capable of adsorbing to a floor surface, a first base material, a decorative layer, an adhesive layer, and a second base material are laminated in this order, and a tubular member.

[0025] In the packaging form of the floor surface adsorption sheet, the floor surface adsorption sheet is not placed on the winding start end in the longitudinal direction of the packing sheet, and the floor surface adsorption sheet is placed along the longitudinal direction of the packing sheet on at least a part of the portion of the packing sheet except for the winding start end, with the surface of the floor surface adsorption sheet opposite to the side where the adhesive layer of the second base material is provided facing the first packing sheet surface. The packing sheet located at the winding start end of the packing sheet on which the floor surface adsorption sheet is placed is made to face the tubular member, and in a state where the floor surface adsorption sheet is placed on the packing sheet, only the packing sheet located at the winding start end is wound around the tubular member with the packing sheet of the floor surface adsorption sheet placed on the packing sheet as the outer peripheral surface side and the floor surface adsorption sheet as the winding core side. Then, the packing sheet on which the floor surface adsorption sheet located other than the winding start end is placed is wound around the outer peripheral surface of the packing sheet wound around the tubular member one or more times to form a roll-shaped product.

[0026] Furthermore, in a region from the outer peripheral surface of the roll-shaped object toward the core side of the first turn, and in a region from the first turn to the outer peripheral surface side of the core side on which the packing sheet is wound in a state in which the floor surface adsorption sheet is placed on the outer peripheral surface of the packing sheet on which only the packing sheet is wound, the first packing sheet surface is in direct contact with the second substrate, and the second packing sheet surface is in direct contact with the adsorption layer.

[0027] In this specification, the terms "first packaging sheet surface" and "second packaging sheet surface" are used for the sake of convenience in order to clarify the positional relationship between the surface of the packaging sheet that contacts the adsorption layer of the floor surface adsorption sheet and the surface of the packaging sheet that contacts the second base material of the floor surface adsorption sheet, but in some cases, the two can be used interchangeably, and the first packaging sheet surface and the second packaging sheet surface can be used interchangeably. The same applies to the second and third aspects of the present invention described below.

[0028] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The present invention is not limited to the contents of the embodiment. In the drawings, some parts are illustrated enlarged or reduced in size to facilitate explanation.

[0029] First Embodiment 1 and 2, an example of a packaging form of the floor surface adsorption sheet according to the present embodiment is shown in schematic form in Fig. 1. Fig. 2 shows a schematic perspective view. Fig. 1 shows a cross-sectional view taken along line II-II in Fig. 1. Fig. 2 shows a schematic cross-sectional view of a stack in which the floor surface adsorption sheet 100 is placed along the X1 direction, which is the longitudinal direction of the packaging sheet 50, cut along the Y1 direction, which is the width direction of the packaging sheet 50.

[0030] As shown in Fig. 1, the floor surface adsorption sheet 100 is placed on top of the first packing sheet surface 51 of the long packing sheet 50 (the direction facing upward in the Z1 direction) so that the adsorption layer 13 of the floor surface adsorption sheet 100 faces upward. Although not shown in Fig. 1, the floor surface adsorption sheet 100 is not placed on the winding start end in the long direction (X1 direction) of the packing sheet 50. The floor surface adsorption sheet 100 is placed along the long direction of the packing sheet 50 on at least a part of the part excluding the winding start end in the long direction of the packing sheet 50. In the roll-shaped object 300, first, at the winding start end, only the packing sheet 50 is wound around the tubular member 70 in the direction of the arrow W. Thereafter, the floor surface adsorption sheet 100 is placed on the outer peripheral surface of the packing sheet 50 wound around the tubular member 70, and the packing sheet 50 is wound around the floor surface adsorption sheet 100 together with the packing sheet 50 in the direction of the arrow W, with the packing sheet 50 on the outer peripheral surface side and the floor surface adsorption sheet 100 on the core side.

[0031] As shown in Fig. 1, the overall dimensions of the floor surface adsorption sheet 100 are smaller than the overall dimensions of the packaging sheet 50. Therefore, the floor surface adsorption sheet 100 is placed along the longitudinal direction of the packaging sheet 50 in a range equal to or less than the length of the direction perpendicular to the longitudinal direction of the packaging sheet 50 (i.e., the width direction Y1 direction). The floor surface adsorption sheet 100 is also placed in a range equal to or less than the length of the longitudinal direction of the packaging sheet 50. Fig. 1 shows a state in which one floor surface adsorption sheet 100 is placed on the packaging sheet 50 along the longitudinal direction of the packaging sheet 50. However, the floor surface adsorption sheet placed on the packaging sheet 50 may be two or more floor surface adsorption sheets placed along the longitudinal direction of the packaging sheet 50 as in a third embodiment described later.

[0032] (Tubular member 70) The tubular member 70 is not particularly limited as long as it is a cylindrical tubular body. The tubular member 70 may be, for example, a paper tube, a resin tube, or a composite tube. The inner diameter of the tubular member 70 may be, for example, 3 inches, 6 inches, or 8 inches. From the viewpoint of compact packaging, the inner diameter of the tubular member 70 is preferably 3 inches.

[0033] (Packing sheet 50) As shown in Fig. 2, the packaging sheet 50 has a first packaging sheet surface 51 and a second packaging sheet surface 52, which is the surface opposite to the first packaging sheet surface 51. The first packaging sheet surface 51 and the second packaging sheet surface 52 are each an uneven surface having unevenness. The unevenness of the first packaging sheet surface 51 and the second packaging sheet surface 52 is not particularly limited, and may be, for example, unevenness having a surface roughness equivalent to the surface state of a fabric containing organic fibers, or unevenness provided by embossing. The degree of unevenness of the first packaging sheet surface 51 and the second packaging sheet surface 52 may be the same or different.

[0034] From the viewpoint of easily suppressing the occurrence of wrinkles in the floor surface adsorption sheet 100, good peelability between the floor surface adsorption sheet 100 and the packaging sheet 50, and easily suppressing the occurrence of winding misalignment when wound in the direction of the arrow W, the packaging sheet 50 is preferably a fabric containing organic fibers. The fabric containing organic fibers may be any of woven fabric, knitted fabric, and nonwoven fabric as long as it contains organic fibers. From the viewpoint of easily suppressing the occurrence of wrinkles in the floor surface adsorption sheet 100, good peelability between the floor surface adsorption sheet 100 and the packaging sheet 50, and easily suppressing the occurrence of winding misalignment when wound in the direction of the arrow W, the fabric containing organic fibers is preferably a fabric containing polyester fibers. The fabric containing organic fibers also preferably includes a woven fabric composed of organic fiber threads, and also preferably includes a woven fabric composed of polyester fiber threads. If the packaging sheet 50 is, for example, a fabric containing organic fibers, it is less likely to tear and has higher durability.

[0035] When the fabric containing organic fibers includes a woven fabric composed of organic fiber threads, the organic fibers constituting the woven fabric preferably have a fineness of, for example, 50 denier or more and 2000 denier or less, from the viewpoints of easily preventing wrinkles in the floor surface adsorption sheet 100, good peelability between the floor surface adsorption sheet 100 and the packaging sheet 50, and easily preventing winding misalignment when wound in the direction of arrow W. From the same viewpoint, the organic fibers constituting the woven fabric are more preferably threads having a fineness of, for example, 100 denier or more and 1000 denier or less, and even more preferably threads having a fineness of 200 denier or more and 500 denier or less. From the viewpoint of easily suppressing the occurrence of wrinkles in the floor surface adsorption sheet 100, good peelability between the floor surface adsorption sheet 100 and the packaging sheet 50, and easily suppressing the occurrence of winding misalignment when wound in the direction of the arrow W, it is preferable that the fabric containing organic fibers has a warp weave density of 20 threads / inch or more and a weft weave density of 80 threads / inch or less. As an example, if the packaging sheet 50 has unevenness on the first packaging sheet surface 51 and the second packaging sheet surface 52, which is formed when the packaging sheet 50 includes a woven fabric composed of organic fiber threads having a fineness of 50 denier or more and 2000 denier or less and a warp weave density of 20 threads / inch or more and a weft weave density of 80 threads / inch or less, the occurrence of wrinkles in the floor surface adsorption sheet 100 is easily suppressed, good peelability between the floor surface adsorption sheet 100 and the packaging sheet 50 is good, and easily suppresses the occurrence of winding misalignment when wound in the direction of the arrow W.

[0036] The fabric containing organic fibers may have an ink-receiving layer, if necessary. When the fabric containing organic fibers has an ink-receiving layer, the ink-receiving layer is provided along the unevenness of the fabric. Therefore, even if the fabric containing organic fibers has an ink-receiving layer, it still has unevenness. The ink-receiving layer contains, for example, a pigment, a binder resin, and additives. The composition of the ink-receiving layer is not particularly limited, and it can be made of known materials.

[0037] (Floor Adhesive Sheet 100) 2, the floor surface adhesive sheet 100 is laminated in the order of the second substrate 31, the adhesive layer 33, the decoration layer 20, the first substrate 11, and the adhesive layer 13 capable of adhering to the floor surface, in that order from the side placed on the packaging sheet 50. The floor surface adhesive sheet 100 is a laminated sheet in which an adhesive sheet main body 10 having a first substrate 11 and an adhesive layer 13 provided directly on one side of the first substrate 11, and a protective sheet 30 having a second substrate 31 and an adhesive layer 33 provided directly on one side of the second substrate 31 are laminated via a decoration layer 20 formed on the surface of the first substrate 11 opposite to the surface on which the adhesive layer 13 is provided.

[0038] The floor surface adsorption sheet 100 is obtained, for example, as follows. First, an adsorption sheet body with a release sheet is prepared, in which an adsorption layer 13 is provided on the releasable surface of a first release sheet (not shown), and a first substrate 11 is provided on the surface of the adsorption layer 13 opposite to the side having the first release sheet. Next, a decorative layer 20 is provided, for example, by printing, on the surface of the first substrate 11 opposite to the side having the adsorption layer 13 in the adsorption sheet body with a release sheet. Separately, a protective sheet with a release sheet is prepared, in which an adhesive layer 33 is provided on the releasable surface of a second release sheet (not shown), and a second substrate 31 is provided on the surface of the adhesive layer 33 opposite to the side having the second release sheet. Next, the second release sheet in the protective sheet with a release sheet is peeled off to expose the adhesive layer 33, and the exposed adhesive layer 33 is pressed against the decorative layer 20. This results in a floor surface adsorption sheet with a release sheet. The first release sheet provided on the adhesive layer 13 is peeled off when the floor surface adsorption sheet 100 is used. Until the floor surface adhesive sheet 100 is used, the adhesive layer 13 is protected by the first release sheet.

[0039] (Adsorption layer 13) The material applied to the adsorption layer 13 is not particularly limited as long as it can be adsorbed when attached to the floor surface and can be peeled off from the floor surface to reuse the floor surface adsorption sheet 100. From the viewpoint of adsorbing to the floor surface and facilitating reuse of the floor surface adsorption sheet 100, the adsorption layer 13 is preferably a foamed sheet of a resin composition containing a crosslinking reaction product of 100 parts by mass of a (meth)acrylic acid ester copolymer resin having an N-methylol group and a glass transition temperature of -10°C or less and 1 part by mass or more and 20 parts by mass or less of a carbodiimide crosslinking agent. The glass transition temperature of the (meth)acrylic acid ester copolymer resin is more preferably -13°C or less. The glass transition temperature of the (meth)acrylic acid ester copolymer resin is preferably -40°C or more. If the glass transition temperature of the (meth)acrylic acid ester copolymer resin is -10°C or less, the adsorption layer 13 is easily adsorbed to the floor surface when attached to the floor surface, and unintended peeling of the adsorption layer 13 from the floor surface is less likely to occur.

[0040] If the adsorption layer 13 is a foamed sheet of a resin composition containing a crosslinking reaction product of 100 parts by mass of a (meth)acrylic acid ester copolymer resin having an N-methylol group and a glass transition temperature of -10°C or less and 1 part by mass or more and 20 parts by mass or less of a carbodiimide-based crosslinking agent, when the floor surface adsorption sheet 100 is placed on the packaging sheet 50 to form the roll-shaped object 300, a gap is likely to be generated between the floor surface adsorption sheet 100 and the packaging sheet 50. This makes it possible to expel air from the gap generated between the floor surface adsorption sheet 100 and the packaging sheet 50. As a result, when the roll-shaped object 300 is formed in a state in which the floor surface adsorption sheet 100 is placed on the packaging sheet 50, the occurrence of wrinkles in the floor surface adsorption sheet 100 is likely to be suppressed, the peelability from the packaging sheet 50 is good, and the occurrence of winding misalignment is likely to be suppressed. Furthermore, if the adsorption layer 13 is a foamed sheet of a resin composition containing a cross-linking reaction product of 100 parts by mass of a (meth)acrylic acid ester copolymer resin having N-methylol groups and a glass transition temperature of -10°C or lower, and 1 part by mass or more and 20 parts by mass or less of a carbodiimide-based cross-linking agent, it is easy to obtain the advantages that the floor surface adsorption sheet 100 can be easily re-attached to the floor surface, and that the occurrence of glue residue when the floor surface adsorption sheet 100 is peeled off from the floor surface is easily suppressed.

[0041] The (meth)acrylic acid ester copolymer resin is preferably composed of 50% by mass or more and 99% by mass or less of constitutional units derived from (meth)acrylic acid ester monomers and 1% by mass or more and 50% by mass or less of constitutional units derived from monomers copolymerizable with (meth)acrylic acid ester monomers, based on the entire (meth)acrylic acid ester copolymer resin (100% by mass).

[0048] The thickness of the adsorption layer 13 is not particularly limited, and may be, for example, 20 μm or more and 100 μm or less.

[0049] (First base material 11) The first substrate 11 has the decorative layer 20 formed on the surface opposite to the surface on which the adsorption layer 13 is provided. The first substrate 11 preferably contains a thermoplastic resin from the viewpoint of durability during use of the floor surface adsorption sheet 100. In addition, from the viewpoint of durability during use of the floor surface adsorption sheet 100 and visibility of the decorative layer 20, the first substrate 11 preferably contains a thermoplastic resin and a filler. From the viewpoint of visibility of the decorative layer 20, strength of the floor surface adsorption sheet 100, flexibility of the floor surface adsorption sheet 100, etc., the first substrate 11 is more preferably a porous resin sheet containing a thermoplastic resin and a filler.

The filler is preferably an inorganic filler. The inorganic filler is preferably at least one selected from the group consisting of calcium carbonate, calcined clay, silica, diatomaceous earth, talc, mica, synthetic mica, sericite, kaolinite, titanium oxide, barium sulfate, and alumina. Among these, the inorganic filler is preferably either or both of calcium carbonate and titanium oxide. The content of the filler is preferably 8% by mass or more and 65% by mass or less with respect to the entire first substrate 11 (100% by mass).

[0052] When the first substrate 11 is a porous resin sheet, the porous resin sheet may contain various additives such as an antioxidant, a light stabilizer, a dispersant, and a lubricant, as necessary.

[0053] From the viewpoint of the strength of the floor surface adhesive sheet 100, the thickness of the first substrate 11 is preferably 20 μm or more and 900 μm or less.

[0054] (Decorative layer 20) The decorative layer 20 is formed on the surface of the first substrate 11 opposite to the surface on which the adsorption layer 13 is provided, and is a layer for performing decoration for the purpose of advertising, guide display, etc. The decorative layer 20 may be decorated with, for example, one of figures, colors, characters, symbols, photographs, patterns, etc., or may be decorated with a combination of these.

[0055] The decorative layer 20 can be formed by a printing method such as letterpress printing, gravure printing, offset printing, screen printing, and inkjet printing. The decorative layer 20 can also be formed by a coating method such as a roll coater, a knife coater, a roll knife coater, an air knife coater, a die coater, a bar coater, a gravure coater, a curtain coater, a spray coater, and a spray gun. The decorative layer 20 can also be formed by a transfer method. From the viewpoint of easy formation, the decorative layer 20 is preferably a printed layer formed by a printing method.

[0056] The thickness of the decorative layer 20 is not particularly limited, and may be, for example, 0.5 μm or more and 3 μm or less.

[0057] (Adhesive layer 33) The adhesive layer 33 is not particularly limited, and can be made of an adhesive composition containing a known adhesive.

[0058] Examples of the adhesive include an acrylic adhesive, a rubber adhesive, a polyester adhesive, and a urethane adhesive. Among these, the adhesive is preferably an acrylic adhesive, from the viewpoint of exhibiting adhesive strength and durability suitable for the protective sheet 30.

[0059] The acrylic pressure-sensitive adhesive preferably comprises as a main component an acrylic polymer (including the concept of a copolymer) containing, as polymer-constituting monomer components, (1) a main monomer component that imparts adhesiveness, (2) a comonomer component that imparts adhesiveness and cohesive strength, and (3) a functional group-containing monomer component for improving crosslinking points and adhesiveness.

[0060] (1) Examples of the main monomer component include (meth)acrylic acid alkyl esters such as ethyl acrylate, butyl (meth)acrylate, amyl acrylate, 2-ethylhexyl (meth)acrylate, octyl acrylate, cyclohexyl (meth)acrylate, benzyl (meth)acrylate, and methoxyethyl acrylate.

[0063] By including each of the above components as polymer-constituting monomer components, the adhesive strength and cohesive strength of the acrylic polymer are improved. In addition, since such an acrylic polymer usually does not have an unsaturated bond in the molecule, the stability against light and oxygen can be improved. Furthermore, depending on the type and molecular weight of the monomer, an acrylic pressure-sensitive adhesive having the desired physical properties can be obtained.

[0064] The adhesive composition containing an adhesive such as an acrylic adhesive may be either a crosslinked type that is subjected to a crosslinking treatment or a non-crosslinked type that is not subjected to a crosslinking treatment.

[0066] The adhesive composition containing an adhesive such as an acrylic adhesive may contain various additives such as a plasticizer, a tackifier, and a stabilizer, if necessary.

[0067] The thickness of the pressure-sensitive adhesive layer 33 is not particularly limited, and is preferably, for example, not less than 5 μm and not more than 150 μm.

[0068] (Second base material 31) The second base material 31 preferably contains a thermoplastic resin. When the second base material 31 contains a thermoplastic resin, the thermoplastic resin may be, for example, at least one resin selected from the group consisting of vinyl chloride resin, polyester resin, olefin resin, urethane resin, and acrylic resin. From the viewpoint of excellent weather resistance, the thermoplastic resin is preferably a vinyl chloride resin.

[0069] The vinyl chloride resin is a polymer having a repeating unit derived from vinyl chloride. The content of the repeating unit derived from vinyl chloride is preferably 50 mol% or more, more preferably 70 mol% or more, of the total repeating units of the vinyl chloride resin. The vinyl chloride resin may be, for example, a homopolymer of vinyl chloride, or a copolymer of a vinyl chloride monomer and a monomer copolymerizable with vinyl chloride. Examples of the monomer copolymerizable with vinyl chloride include at least one monomer selected from the group consisting of vinyl acetate, acrylonitrile, styrene, (meth)acrylic acid ester, ethylene, propylene, butylene, and olefin halides. Specific examples of the vinyl chloride resin include copolymers such as polyvinyl chloride, ethylene-vinyl chloride copolymer, vinyl acetate-vinyl chloride copolymer, and vinyl chloride-halogenated olefin copolymer. The vinyl chloride resin may be used alone or in combination of two or more types.

[0070] When the second base material 31 contains a vinyl chloride resin as a thermoplastic resin, it may be used in combination with other resins. The other resins are preferably resins that are highly compatible with the vinyl chloride resin. Specific examples of the other resins include polyester resins, epoxy resins, acrylic resins, vinyl acetate resins, urethane resins, acrylonitrile-styrene-butadiene copolymers, and partially saponified polyvinyl alcohol. When the vinyl chloride resin is mixed with the other resins, the blending amount of the other resins is preferably 1 part by mass or more and 50 parts by mass or less with respect to 100 parts by mass of the vinyl chloride resin.

[0071] The vinyl chloride resin is preferably plasticized with a plasticizer or a polymer blend.

These plasticizers can be used alone or in combination of two or more.

[0072] The amount of the plasticizer added is preferably 5 parts by mass or more and 100 parts by mass or less based on 100 parts by mass of the vinyl chloride resin.

[0073] The second substrate 31 may contain additives, such as stabilizers, UV absorbers, metal soaps, antioxidants, antistatic agents, antifogging agents, pigments, dyes, fillers, flame retardants, fragrances, lubricants, and surfactants, as necessary.

[0074] The thickness of the second base material 31 is not particularly limited, and is preferably, for example, not less than 10 μm and not more than 1000 μm.

[0075] 2 again, the floor surface adsorption sheet 100 is placed along the longitudinal direction (X1 direction) of the packing sheet 50, with the surface of the floor surface adsorption sheet 100 opposite the surface on which the adhesive layer 33 of the second base material 31 is provided facing the first packing sheet surface 51. As shown in FIG. 2, the floor surface adsorption sheet 100 is placed within the length of the packing sheet 50 in the width direction (Y1 direction).

[0076] Referring to Figure 3, Figure 3 shows a schematic representation of a roll-shaped object 300 in which a floor surface adsorption sheet 100 is wound around a tubular member 70 with a packaging sheet 50 interposed therebetween, and also shows a schematic enlarged cross-sectional view of the same.

[0077] 3 is a region on the winding core side where only the packing sheet 50 is wound around the tubular member 70. In region C, a portion of the packing sheet 50 that corresponds to the winding start end in the longitudinal direction is wound around the tubular member 70.

[0078] The region B is a region from the outer peripheral surface of the rolled object 300 toward the core side to the first turn in the portion where the packing sheet 50 is wound with the floor surface adsorption sheet 100 placed thereon, and includes a portion where the packing sheet 50 and the floor surface adsorption sheet 100 overlap in this order from the outer peripheral surface toward the core side. In the region B, the second packing sheet surface 52 forms the outer peripheral surface of the rolled object 300, and the first packing sheet surface 51 contacts the second base material 31 of the floor surface adsorption sheet 100. In the region B, the adsorption layer 13 of the floor surface adsorption sheet 100 contacts the packing sheet 50 located at the second turn from the outer peripheral surface toward the core side. In the region B, even if the floor surface adsorption sheet 100 is not placed on the end end of the packing sheet 50, the end end of the packing sheet 50 also corresponds to the portion where the packing sheet 50 is wound with the floor surface adsorption sheet 100 placed thereon. Furthermore, as will be described in the third embodiment below, even if multiple adjacent floor surface adsorption sheets 100A are placed at a distance from each other on the packing sheet 50 and there are areas on the packing sheet 50 where the floor surface adsorption sheets 100A are not placed, these areas correspond to the rolled-up portions of the packing sheet 50 on which the floor surface adsorption sheets 100A are placed.

[0079] In the wound portion of the packing sheet 50 with the floor surface adsorption sheet 100 placed thereon, region A begins from the packing sheet 50 located at the second turn from the outer circumferential surface toward the core side. In the wound portion of the packing sheet 50 with the floor surface adsorption sheet 100 placed thereon, region A ends at the portion corresponding to the first turn from the core side. In other words, region A is a region closer to the core side than the first turn from the outer circumferential surface of the rolled object 300, and is a region from the first turn to the outer circumferential surface side on the core side of the wound packing sheet 50 with the floor surface adsorption sheet 100 placed thereon, on the outer circumferential surface of the packing sheet 50 with only the packing sheet 50 wound around the tubular member 70. In other words, region A is a region between region C and region B.

[0080] In region A, the packing sheet 50 is disposed on the outer peripheral surface side, and the floor surface adsorption sheet 100 is disposed on the core side. In region A, this arrangement is repeated from the outer peripheral surface side toward the core side until region C is reached. Therefore, as shown in Fig. 3, in a cross-sectional view of the rolled object 300, from the core side toward the outer peripheral surface, region C where only the packing sheet 50 is wound, region A where the packing sheet 50 with the floor surface adsorption sheet 100 placed thereon is wound one or more times on the outer peripheral surface side of region C, and region B where the packing sheet 50 with the floor surface adsorption sheet 100 placed thereon is wound for the last turn is formed on the outer peripheral surface side of region A. 3, in region A, the second packaging sheet surface 52 of the packaging sheet 50 is in direct contact with the adsorption layer 13 of the floor surface adsorption sheet 100, and the first packaging sheet surface 51 of the packaging sheet 50 is in direct contact with the second base material 31 of the floor surface adsorption sheet 100. Although not shown, the rolled object 300 may be fastened using a known fastening means such as a tightening band made of resin, rubber, or the like so that the rolled object 300 cannot be easily unwound.

[0081] (Effects of the First Embodiment) According to this embodiment, the following advantageous effects can be obtained. (1) By using a packaging sheet 50 having unevenness on the first packaging sheet surface 51 and the second packaging sheet surface 52, and forming a roll-shaped object 300 with the floor surface adsorption sheet 100 placed on the packaging sheet 50, a gap is generated between the floor surface adsorption sheet 100 and the packaging sheet 50 due to the unevenness of the first packaging sheet surface 51 and the second packaging sheet surface 52. Since air can be expelled from this gap, when forming the roll-shaped object 300 with the floor surface adsorption sheet 100 placed on the packaging sheet 50, the occurrence of wrinkles in the packaging sheet 50 is suppressed, and the occurrence of misalignment during winding in the direction of the arrow W is suppressed. In addition, even if meandering occurs during winding in the direction of the arrow W, the meandering can be easily corrected. Furthermore, due to the unevenness of the first packaging sheet surface 51 and the second packaging sheet surface 52, the floor surface adsorption sheet 100 can be easily peeled off from the packaging sheet 50 when reused. (2) In at least a portion of the packing sheet 50 in the longitudinal direction excluding the winding start end, the surface of the floor surface adsorption sheet 100 opposite the side on which the adhesive layer 33 of the second base material 31 is provided is placed against the first packing sheet surface 51, and the floor surface adsorption sheet 100 is placed along the longitudinal direction of the packing sheet 50 to form the roll-shaped object 300. The roll-shaped object 300 thus formed is configured such that the first packing sheet surface 51 and the second base material 31 are in direct contact with each other, and the second packing sheet surface 52 and the adsorption layer 13 are in direct contact with each other in region A, which is a region from the outer peripheral surface of the roll-shaped object 300 toward the core side of the first turn on the outer peripheral surface of the packing sheet 50 in the portion where only the packing sheet 50 is wound around the tubular member 70, from the first turn on the core side on which the packing sheet on which the floor surface adsorption sheet is placed is wound. By configuring in this manner, the occurrence of delamination of the floor surface adsorbing sheet 100 when the roll-shaped object 300 is formed is suppressed. (3) The floor surface adsorption sheet 100 is not placed on the start end of the winding in the longitudinal direction of the packing sheet 50, and only the packing sheet 50 located at the start end of the winding is wound around the tubular member 70. This prevents the transfer of the texture of the surface of the tubular member 70 and prevents impressions on the floor surface adsorption sheet 100 caused by unevenness due to the start end of the winding. (4) For example, by adopting the packaging form of the floor adhesive sheet according to this embodiment for floor surfaces used in sports in indoor environments such as gymnasiums, the lifespan of the floor adhesive sheet is extended, making it possible to reuse it repeatedly.

[0082] Second Embodiment Next, an example of the packaging form of the floor surface adsorption sheet according to this embodiment will be described with reference to Figures 4(A) and 4(B). Figures 4(A) and 4(B) show schematic diagrams showing an example of the packaging form of the floor surface adsorption sheet. Specifically, Figures 4(A) and 4(B) show schematic cross-sectional views showing the state in which the roll-shaped material 300 described in the first embodiment is contained in a packaging box 90. Figure 4(B) is a schematic diagram viewed from the side in the direction of the arrow V shown in Figure 4(A).

[0083] The packaging form according to the second embodiment differs from that according to the first embodiment in that the roll-shaped material 300 described in the first embodiment is housed in a packaging box 90. In the following description, differences from the first embodiment will be mainly described, and overlapping descriptions will be omitted or simplified. The same reference numerals will be used to designate the same components as those in the first embodiment, and descriptions thereof will be omitted or simplified.

[0084] Hereinafter, an example of the present embodiment will be described with reference to the drawings. The present invention is not limited to the contents of the embodiment. In the drawings, some parts are illustrated enlarged or reduced in size in order to facilitate explanation.

[0085] As shown in FIG. 4(A) and FIG. 4(B), the packaging form according to this embodiment includes a packaging box 90, a flange 80 having a protruding portion 81 at the center thereof that can be fitted into the tubular member 70, and the roll-shaped material 300 described in the first embodiment. In the packaging form according to this embodiment, the protruding portion 81 is fitted into both ends of the tubular member 70 around which the roll-shaped material 300 is wound (i.e., both ends of the tubular member 70 included in the roll-shaped material 300). In the roll-shaped material 300 including the tubular member 70 into which the protruding portion 81 is fitted, the outer diameter of the roll-shaped material 300 is smaller than the length of the flange 80 in the height direction. The length of the flange 80 in the height direction is the length from the bottom surface 84 to the top surface 85 of the flange 80, and is the dimension in the Z2 direction. The outer diameter of the roll-shaped material 300 is smaller than the length of the flange 80 in the width direction. The width direction length of the flange 80 is the length from one side surface 83 of the flange 80 to the other side surface 83, and is the dimension in the X2 direction. The roll-shaped object 300 including the tubular member 70 with the protruding portion 81 fitted therein is contained in a packaging box 90.

[0086] The roll-shaped object 300 including the tubular member 70 into which the protrusion 81 is fitted is a flanged roll-shaped object 301. The flange 80 is a member that supports the roll-shaped object 300. The protrusion 81 is fitted into the tubular member 70, thereby supporting the roll-shaped object 300. The flange 80 has an outer diameter that is rectangular so as to be accommodated in the packaging box 90. The protrusion 81 of the flange 80 is, for example, cylindrical or columnar. The material constituting the flange 80, including the protrusion 81, is not particularly limited, and may be made of resin, paper, or a composite material composed of different materials. The protrusion 81 may have a diameter such that, when the protrusion 81 is fitted into both ends of the tubular member 70, a gap of, for example, 0.1 mm or more and 1.0 mm or less is generated between the tubular member 70 and the protrusion 81.

[0087] The height (Z2 direction) and width (X2 direction) dimensions of the flange 80 are larger than the outer diameter of the rolled material 300. Therefore, the rolled material 300 of the flanged rolled material 301 does not come into contact with the inner surface of the packaging box 90.

[0088] The packaging box 90 is a box for storing the roll-shaped material 300 described in the first embodiment together with the flange 80. The material constituting the packaging box 90 is not particularly limited, and may be made of resin, paper, or a composite material composed of different types of materials.

[0089] As shown in Fig. 4(A) and Fig. 4(B), the packaging box 90 includes a rolled material 300 and two flanges 80 each having a protruding portion 81, and is formed to a size that accommodates the flanged rolled material 301 in which the protruding portion 81 of the flange 80 is fitted into both ends of the tubular member 70 of the rolled material 300. The longitudinal dimension (Y2 direction) of the packaging box 90 is a dimension in which the back surface 82 on the side not having the protruding portion 81 of the flange 80 almost abuts against the inner surface of the packaging box 90, and the transverse dimension (X2 direction) of the packaging box 90 is formed to a dimension in which the side surface 83 of the flange 80 almost abuts against the inner surface of the packaging box 90. Here, the dimension in which the flange 80 almost abuts against the inner surface of the packaging box 90 is a dimension in which the flange 80 directly abuts against the inner surface of the packaging box 90, or a gap of, for example, 0.1 mm or more and 3 mm or less is generated. In the height direction (Z2 direction) of the packaging box 90, the bottom surface 84 of the flange 80 of the flanged roll-like object 301 is almost in contact with the inner surface of the packaging box 90, and the upper surface 85 of the flange 80 is not in contact with the inner surface of the packaging box 90. The dimension in the height direction of the packaging box 90 is formed to have a dimension that has a space between the upper surface 85 of the flange 80 of the flanged roll-like object 301 and the inner surface of the packaging box 90. However, the dimension in the height direction of the packaging box 90 is not limited to this, and may be formed to have a dimension such that the upper surface 85 of the flange 80 of the flanged roll-like object 301 is almost in contact with the inner surface of the packaging box 90.

[0090] In this embodiment, the packaging box 90 is configured such that an upper portion 91 of the packaging box 90 can be opened and closed, and is formed into a structure that allows the flanged rolled object 301 to be stored from the upper portion 91 of the packaging box 90. In addition, the flanged rolled object 301 can be removed from the upper portion 91 of the packaging box 90.

[0091] (Effects of the second embodiment) According to this embodiment, it is possible to achieve the same operational effects as those (1) to (4) of the first embodiment. Furthermore, according to this embodiment, it is possible to achieve the following operational effects. (5) Since the flanged rolled material 301, in which the protruding portions 81 of the flanges 80 are fitted into both ends of the tubular member 70 of the rolled material 300, is contained in the packaging box 90, damage to the rolled material 300 is suppressed. (6) In the flanged rolled material 301, the rolled material 300 is packed in a manner that does not contact the inner surface of the packing box 90. Therefore, even if the packing box 90 containing the flanged rolled material 301 receives an impact during storage or transportation, the rolled material 300 is less susceptible to the impact, and damage to the rolled material 300 is suppressed. As a result, the durability of the floor surface adsorption sheet 100 is increased.

[0092] [Packing method] A second aspect of the present invention is a method for packaging a floor surface adhesive sheet. The method for packaging floor surface adhesive sheets according to the second aspect of the present invention includes the steps of: preparing a long-sized packaging sheet having a first packaging sheet surface and a second packaging sheet surface that is an opposite surface of the first packaging sheet surface, the first packaging sheet surface and the second packaging sheet surface having projections and recesses; A step (step P2A) of preparing a floor surface adhesive sheet in which an adhesive layer capable of being adhered to a floor surface, a first substrate, a decorative layer, an adhesive layer, and a second substrate are laminated in this order; A step of preparing a tubular member (step P3A); a step (step P4A) of placing the floor surface adsorption sheet on the start end of the winding in the longitudinal direction of the packing sheet, and placing the floor surface adsorption sheet along the longitudinal direction of the packing sheet on at least a part of the portion of the packing sheet excluding the start end of the winding in the longitudinal direction, with the surface of the floor surface adsorption sheet opposite to the side on which the adhesive layer of the second base material is provided facing the first packing sheet surface; a step (step P5A) of placing the floor surface adsorption sheet on the packing sheet, and then facing the packing sheet located at the winding start end to the tubular member, and in a state in which the floor surface adsorption sheet is placed on the packing sheet, winding only the packing sheet located at the winding start end around the tubular member with the packing sheet of the floor surface adsorption sheet placed on the packing sheet as the outer peripheral surface side and the floor surface adsorption sheet as the winding core side; and a step (step P6A) of winding the packing sheet, on which the floor surface adsorption sheet is placed at a position other than the starting end of winding, around the outer peripheral surface of the packing sheet wound around the tubular member, one or more times to form a roll-shaped object.

[0093] Furthermore, in a region from the outer peripheral surface of the roll-shaped object toward the core side of the first turn, and in a region from the first turn to the outer peripheral surface side of the core side on which the packing sheet is wound in a state in which the floor surface adsorption sheet is placed on the outer peripheral surface of the packing sheet on which only the packing sheet is wound, the first packing sheet surface is in direct contact with the second substrate, and the second packing sheet surface is in direct contact with the adsorption layer.

[0094] <Third embodiment> Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The present invention is not limited to the contents of the embodiment. In the drawings, some parts are illustrated enlarged or reduced in size to facilitate explanation.

[0095] Referring to Figures 5(A), 5(B), 5(C), 5(D), and 5(E), Figures 5(A), 5(B), 5(C), 5(D), and 5(E) show explanatory diagrams showing an example of a packaging method for the floor surface adsorption sheet of this embodiment.

[0096] This embodiment is a packaging method for packaging a plurality of floor surface adsorption sheets 100A on one packaging sheet 50 in the form of a roll described in the first embodiment, for example, when one pattern is drawn across multiple floor surface adsorption sheets 100A. The floor surface adsorption sheets 100A have the same configuration as the floor surface adsorption sheets 100 in the first embodiment, except that there are multiple floor surface adsorption sheets 100A. Note that the plurality of floor surface adsorption sheets 100A is not limited to the case where one pattern is drawn across multiple floor surface adsorption sheets 100A.

[0097] 5(A), in the step of preparing a packing sheet 50 (step P1A), a long packing sheet 50 having projections and recesses on a first packing sheet surface 51 and a second packing sheet surface 52 is prepared. A specific example of the packing sheet 50 is the same as the specific example described in the first embodiment. In addition, in the step of preparing the floor surface adsorption sheet 100A (step P2A), a floor surface adsorption sheet 100A is prepared having an adsorption layer 13 on one side and a second base material 31 on the other side. As described above, the floor surface adsorption sheet 100A has the same configuration as the floor surface adsorption sheet 100 in the first embodiment, and therefore a specific example of the floor surface adsorption sheet 100A is the same as the specific example described in the first embodiment. 5(B), in a step of preparing a tubular member 70 (step P3A), a tubular member 70 is prepared. A specific example of the tubular member 70 is similar to the specific example described in the first embodiment.

[0098] In the step (step P4A) of placing the floor surface adsorption sheet 100A along the longitudinal direction (X1 direction) of the packing sheet 50, as shown in Fig. 5(A), the floor surface adsorption sheet 100A is placed so that the surface of the floor surface adsorption sheet 100A opposite to the surface on which the adhesive layer 33 of the second base material 31 is provided faces the first packing sheet surface 51 of the packing sheet 50. When the floor surface adsorption sheet 100A is placed on the packing sheet 50, the second base material 31 side of the floor surface adsorption sheet 100A faces the packing sheet 50 and faces downward in the Z1 direction, and the adsorption layer 13 of the floor surface adsorption sheet 100A faces upward in the Z1 direction. Then, as shown in Fig. 5(B), the floor surface adsorption sheet 100A is not placed on the winding start end S in the longitudinal direction of the packing sheet 50. The winding start end S is, for example, an area in which only the packing sheet 50 can be wound around the outer circumferential surface of the tubular member 70 by approximately one revolution. The area in which only the packing sheet 50 can be wound around the outer circumferential surface of the tubular member 70 by approximately one revolution can be, for example, a dimension that is 0.9 times or more and 1.1 times or less the outer circumference of the tubular member 70.

[0099] As shown in FIG. 5(B), the floor surface adsorption sheet 100A is placed on the middle part M of the packing sheet 50, which is the part excluding the winding start end part S in the longitudinal direction (X1 direction). When placing the floor surface adsorption sheet 100A, the floor surface adsorption sheet 100A is placed on at least a part of the middle part M. Since the floor surface adsorption sheet 100A is smaller than the dimension of the packing sheet 50 in the width direction (Y1 direction), there are parts in the width direction of the packing sheet 50 where the floor surface adsorption sheet 100A is not placed. In addition, multiple floor surface adsorption sheets 100A are placed in the longitudinal direction of the packing sheet 50. The multiple floor surface adsorption sheets 100A may be placed along the longitudinal direction of the packing sheet 50 with a space between adjacent floor surface adsorption sheets 100A, or may be placed without any gaps between adjacent floor surface adsorption sheets 100A. From the viewpoint of ease of rolling up the packaging sheet 50 on which a plurality of floor surface adsorption sheets 100A are placed, it is preferable to place the floor surface adsorption sheets 100A so that they are spaced apart from each other. In Fig. 5(B), the floor surface adsorption sheets 100A are placed so that they are spaced apart from each other on the packaging sheet 50. Furthermore, as shown in Fig. 5(D), from the viewpoint of preventing the floor surface adsorption sheets 100A from protruding when the roll-shaped object 300A is formed, it is preferable not to place the floor surface adsorption sheets 100A on the end E of the packing sheet 50 in the longitudinal direction.

[0100] In the process (process P5A) of winding only the packing sheet 50 located at the winding start end S, as shown in Fig. 5(B), the floor surface adsorption sheet 100A is placed on the packing sheet 50 at the middle part M, and then the tubular member 70 is made to face the packing sheet 50 located at the winding start end S. Then, as shown in Fig. 5(C), with the multiple floor surface adsorption sheets 100A placed on the packing sheet 50, only the packing sheet 50 located at the winding start end S is wound around the tubular member 70, for example, about once in the direction of the arrow W, with the packing sheet 50 on the outer circumferential surface side and the multiple floor surface adsorption sheets 100A on the winding core side.

[0101] In the step of forming the roll-shaped object 300A (step P6A), as shown in Fig. 5(D), only the packing sheet 50 located at the winding start end S is wound around the tubular member 70, and then the packing sheet 50 on which the plurality of floor surface adsorption sheets 100A are placed is wound around the outer peripheral surface of the packing sheet 50 wound around the tubular member 70, one or more times in the direction of the arrow W. By this operation, the roll-shaped object 300A is formed, as shown in Fig. 5(E). As described in Figure 3, the formed roll-shaped material 300A is in a region from the first turn of the outer peripheral surface of the roll-shaped material 300A toward the core side, and in a region from the first turn to the outer peripheral surface side of the core side on which the packing sheet 50 is wound in a state in which the floor surface adsorption sheet 100A is placed on the outer peripheral surface of the packing sheet 50 in which only the packing sheet 50 is wound around the tubular member 70, the second packing sheet surface 52 of the packing sheet 50 is in direct contact with the adsorption layer 13 of the floor surface adsorption sheet 100A, and the first packing sheet surface 51 of the packing sheet 50 is in direct contact with the second base material 31 of the floor surface adsorption sheet 100A.

[0102] The packaging method according to this embodiment may include, after the step of forming the roll-shaped material 300A, a step of fastening the roll-shaped material 300A with, for example, a tightening band made of resin, rubber, or the like, as necessary, so as to prevent the roll-shaped material 300A from being easily unwound.

[0103] (Effects of the Third Embodiment) According to this embodiment, the following advantageous effects can be obtained. (1) By using a packing sheet 50 having unevenness on the first packing sheet surface 51 and the second packing sheet surface 52, and by winding the packing sheet 50 with a plurality of floor surface adsorption sheets 100A placed thereon, a gap is generated between the floor surface adsorption sheet 100A and the packing sheet 50 due to the unevenness of the first packing sheet surface 51 and the second packing sheet surface 52. When the packing sheet 50 is wound with the floor surface adsorption sheet 100A placed thereon, air can be expelled from the gap between the plurality of floor surface adsorption sheets 100A and the packing sheet 50, so that the occurrence of wrinkles in the packing sheet 50 is suppressed. In addition, since the air can be expelled, even if meandering occurs when winding the packing sheet 50 with the floor surface adsorption sheet 100A placed thereon, it can be easily corrected. In addition, the occurrence of misalignment during winding when the packing sheet 50 is wound with the floor surface adsorption sheet 100A placed thereon is suppressed. (2) By using a packaging sheet 50 having unevenness on the first packaging sheet surface 51 and the second packaging sheet surface 52 and placing the floor surface adsorption sheet 100A on the packaging sheet 50, the floor surface adsorption sheet 100A can be easily peeled off from the packaging sheet 50 when reused. (3) The second base materials 31 of the multiple floor surface adsorption sheets 100A are placed on the packaging sheet 50 so that they face each other, and only the packaging sheet 50 is wound around the outer circumferential surface of the tubular member 70. After that, with the multiple floor surface adsorption sheets 100A placed on the packaging sheet 50, the multiple floor surface adsorption sheets 100A are wound in the direction of the arrow W with the multiple floor surface adsorption sheets 100A as the core side and the packaging sheet 50 as the outer circumferential surface side. In this way, the adsorption layer of the floor surface adsorption sheet 100A is wound without being attached to the packaging sheet 50 in advance, thereby suppressing the occurrence of delamination of the floor surface adsorption sheet 100A. (4) By not placing the floor surface adsorption sheet 100A on the starting end S of the winding in the longitudinal direction of the packing sheet 50 and by having a process of winding only the packing sheet 50 located at the starting end S around the tubular member 70, the transfer of the texture of the surface of the tubular member 70 and the imprinting of the floor surface adsorption sheet 100A due to the unevenness caused by the starting end S of the winding are suppressed. (5) For example, by adopting the packaging method for the floor adhesive sheet according to the present embodiment to the floor surface used in sports in indoor environments such as gymnasiums, the lifespan of the floor adhesive sheet is extended, making it possible to reuse it repeatedly.

[0104] <Fourth embodiment> Next, an example of a method for packaging the floor adsorption sheet according to this embodiment will be described with reference to Fig. 6(A), Fig. 6(B), and Fig. 6(C). Fig. 6(A), Fig. 6(B), and Fig. 6(C) show explanatory diagrams illustrating an example of a method for packaging the floor adsorption sheet. Specifically, the diagrams show an outline of the process of storing the roll-shaped material 300A described in the third embodiment in the packaging box 90 described in the second embodiment.

[0105] The packaging method according to the fourth embodiment differs from the third embodiment in that it includes a step of housing in a packaging box 90 the rolled material 300A obtained by the packaging method described in the third embodiment. In the following description, differences from the second and third embodiments will be mainly described, and overlapping descriptions will be omitted or simplified. Also, the same reference numerals will be used to designate the same components as those in the first to third embodiments, and descriptions thereof will be omitted or simplified.

[0106] Hereinafter, an example of the present embodiment will be described with reference to the drawings. The present invention is not limited to the contents of the embodiment. In the drawings, some parts are illustrated enlarged or reduced in size in order to facilitate explanation.

[0107] In this embodiment, there is a process of preparing a packaging box 90 (process P7A), A step (step P8A) of preparing a flange 80 having a protruding portion 81 at its center that can be fitted into the tubular member 70; A step (step P9A) of fitting the protrusions 81 into both end portions 71 (71A, 71B) of the tubular member 70 around which the roll-shaped material 300A is wound; The method includes a step (step P10A) of housing the roll-shaped material 300A including the tubular member 70 into which the protrusion 81 is fitted, in a packaging box 90.

[0108] In the step of preparing the packaging box 90 (step P7A), a specific example of the packaging box 90 is similar to the specific example described in the second embodiment. In the step of preparing the protruding portion 81 (step P8A), two flanges 80 are prepared as shown in Fig. 6(A). Note that one flange 80, in which the protruding portion 81 is fitted into the first end portion 71A of the tubular member 70, may be referred to as a first flange, and the other flange 80, in which the protruding portion 81 is fitted into the second end portion 71B of the tubular member 70, may be referred to as a second flange. Also, the protruding portion 81 provided on the first flange may be referred to as a first protruding portion, and the protruding portion 81 provided on the second flange may be referred to as a second protruding portion. Specific examples of the flanges 80 are similar to those described in the second embodiment.

[0109] In the step of fitting the protrusion 81 (step P9A), as shown in FIG. 6(A) and FIG. 6(B), the protrusion 81 of the flange 80 is fitted into each of the first end 71A and the second end 71B of the tubular member 70 of the roll-shaped object 300A. Specifically, the first protrusion (protrusion 81) of the first flange (flange 80) is fitted into the first end 71A of the tubular member 70, and the second protrusion (protrusion 81) of the second flange (flange 80) is fitted into the second end 71B of the tubular member 70. This forms a flanged roll-shaped object 301A, which is the roll-shaped object 300A including the tubular member 70 into which the protrusion 81 is fitted. In the flanged roll-shaped object 301A, the outer diameter of the roll-shaped object 300A is smaller than the height direction length and the width direction length of the flange 80. A specific example of the flanged roll-shaped material 301A is the same as the specific example of the flanged roll-shaped material 301 described in the second embodiment. A specific example of the tubular member 70 is the same as the specific example described in the first embodiment.

[0110] In the process of placing in packaging box 90 (process P10A), as shown in Fig. 6(C), flanged roll-shaped material 301A is placed in packaging box 90. In this embodiment, when flanged roll-shaped material 301A is placed in packaging box 90, it can be placed in packaging box 90 from top 91.

[0111] (Functions and Effects of the Fourth Embodiment) According to this embodiment, it is possible to achieve the same operational effects as those (1) to (5) of the third embodiment. Furthermore, according to this embodiment, it is possible to achieve the following operational effects. (6) Since the method includes a process of storing the flanged rolled material 301A, in which the protrusions 81 of the flanges 80 are fitted into both ends 71 ​​(71A, 71B) of the tubular member 70 of the rolled material 300A, in a packaging box 90, damage to the rolled material 300A is suppressed. (7) In the process of storing the flanged rolled object 301A in the packaging box 90, the packaging method is such that the rolled object 300A is positioned so as not to come into contact with the inner surface of the packaging box 90. Therefore, even if the packaging box 90 storing the flanged rolled object 301A receives an impact during storage or transportation, the rolled object 300A is less susceptible to the impact. As a result, damage to the rolled object 300A is suppressed. As a result, the durability of the floor surface adsorption sheet 100A is increased.

[0112] [Reuse method] A third aspect of the present invention is a method for reusing a floor surface adhesive sheet. The floor surface adhesive sheet according to the third aspect of the present invention includes a step (step P1B) of preparing a floor surface adhesive sheet with a release sheet, the floor surface adhesive sheet being formed by laminating a release sheet, an adhesive layer capable of adhering to a floor surface, a first substrate, a decorative layer, an adhesive layer, and a second substrate in this order; A step (step P2B) of peeling off the release sheet to obtain a floor surface adsorption sheet exposing the adsorption layer; A step of adsorbing the exposed adsorption layer onto a bed surface (step P3B); A step of removing the floor surface adsorption sheet from the floor surface (step P4B); A process (process P5B) of preparing a long-sized packaging sheet having a first packaging sheet surface and a second packaging sheet surface that is an opposite surface of the first packaging sheet surface, the first packaging sheet surface and the second packaging sheet surface having unevenness; A step of preparing a tubular member (step P6B); a step (step P7B) of placing the floor surface adsorption sheet on the start end of the winding in the longitudinal direction of the packing sheet, and placing the floor surface adsorption sheet on at least a portion of the packing sheet except for the start end of the winding in the longitudinal direction of the packing sheet, with the surface of the floor surface adsorption sheet removed from the floor surface opposite the side on which the adhesive layer of the second base material is provided facing the first packing sheet surface; a step (step P8B) of placing the floor surface adsorption sheet on the packaging sheet, and then facing the packaging sheet located at the winding start end to the tubular member, and in a state in which the floor surface adsorption sheet is placed on the packaging sheet, winding only the packaging sheet located at the winding start end around the tubular member with the packaging sheet of the floor surface adsorption sheet placed on the packaging sheet as the outer peripheral surface side and the floor surface adsorption sheet as the winding core side; a step of winding the packing sheet, on which the floor surface adsorption sheet is placed at a position other than the winding start end, around the outer peripheral surface of the packing sheet wound around the tubular member, at least once to form a roll-shaped product, and storing the roll-shaped product (step P9B); A step (step P10B) of unwinding the roll-shaped material and separating the packing sheet and the floor surface adsorption sheet to obtain the floor surface adsorption sheet with the adsorption layer exposed; and a step (step P11B) of adsorbing the exposed adsorption layer onto a bed surface.

[0113] During the time until the stored roll-like material is unwound, the first packaging sheet surface is in direct contact with the second substrate, and the second packaging sheet surface is in direct contact with the adsorption layer in the area from the first turn from the outer peripheral surface of the roll-like material toward the core side of the first turn on the outer peripheral surface side of the core on which the packing sheet is wound with the floor surface adsorption sheet placed on the outer peripheral surface of the packing sheet on which only the packing sheet is wound.

[0114] <Fifth embodiment> Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The present invention is not limited to the contents of the embodiment. In the drawings, some parts are illustrated enlarged or reduced in size to facilitate explanation.

[0115] Referring to Figures 7(A) and 7(B), and Figures 8(A), 8(B), and 8(C), Figures 7(A) and 7(B), and Figures 8(A), 8(B), and 8(C) show an explanatory diagram showing an example of a method for reusing a floor adsorption sheet according to this embodiment. Figures 7(A) and 7(B) show the process of attaching a floor adsorption sheet with a release sheet to a floor, and Figures 8(A), 8(B), and 8(C) show the process of peeling off the floor adsorption sheet attached to the floor and reusing it.

[0116] In the step of preparing a floor surface adsorption sheet with a release sheet (step P1B), as shown in Fig. 7(A), a floor surface adsorption sheet with a release sheet 200 is prepared in which a release sheet 60, an adsorption layer 13 capable of adsorbing to a floor surface, a first base material 11, a decoration layer 20, an adhesive layer 33, and a second base material 31 are laminated in this order. The floor surface adsorption sheet with a release sheet 200 has the same configuration as the floor surface adsorption sheet 100 described in the first embodiment, except that the release sheet 60 is attached to the adsorption layer 13 of the floor surface adsorption sheet 100B. A specific example of the floor surface adsorption sheet 100B is the same as the specific example of the floor surface adsorption sheet 100 described in the first embodiment. In Fig. 7(A), the floor surface adsorption sheet 100B is an unused floor surface adsorption sheet.

[0117] The release sheet 60 is attached to protect the adsorption layer 13 until the floor surface adsorption sheet 100B is used. The release sheet 60 is not particularly limited, and a known release sheet having a surface having releasability can be used. For example, the release sheet 60 can be a release sheet having a release base material and a release agent layer formed on the release base material by a release agent. For example, the release base material can be a resin sheet, a foamed resin sheet, glassine paper, coated paper, and laminated paper. For example, the release agent can be a silicone-based release agent, a fluorine-based release agent, a carbamate release agent containing a long chain alkyl group, and the like. The release sheet 60 corresponds to the first release sheet described in the first embodiment.

[0118] The thickness of the release sheet 60 is preferably, for example, not less than 10 μm and not more than 250 μm.

[0119] In the step (step P2B) of obtaining the floor surface adsorption sheet 100B with the adsorption layer 13 exposed, the release sheet 60 is peeled off in the direction of the arrow R1 as shown in Fig. 7(A), thereby exposing the adsorption layer 13 of the floor surface adsorption sheet 100B. This results in the floor surface adsorption sheet 100B with the adsorption layer 13 exposed.

[0120] In the step (step P3B) of adhering the exposed adhesive layer 13 to the floor surface F, as shown in FIG. 7B, the adhesive layer 13 of the floor surface adhesive sheet 100B is attached to the floor surface F and adsorbed thereto. In this manner, the floor surface adhesive sheet 100B is used. For example, when one pattern is drawn across multiple floor surface adhesive sheets 100B, multiple floor surface adhesive sheets 100B are used. In this case, multiple floor surface adhesive sheets 100B are prepared, the adhesive layer 13 is exposed for each of the multiple floor surface adhesive sheets 100B, and each exposed adhesive layer 13 is attached to the floor surface F. When each exposed adhesive layer 13 is attached to the floor surface F, the adjacent floor surface adhesive sheets 100B are attached in a row without any gaps between them, thereby completing one pattern.

[0121] The floor surface adsorption sheet 100B can be used in both indoor and outdoor environments. For example, from the viewpoint of ease of reuse, the floor surface adsorption sheet 100B is preferably used in an indoor environment. When the floor surface adsorption sheet is used in an indoor environment, the place of use is not particularly limited. An example of the floor surface adsorption sheet 100B being used in an indoor environment is the floor surface of an indoor sports venue.

[0122] In the step of removing the floor surface adsorption sheet 100B (step P4B), as shown in Fig. 8(A), after use of the floor surface adsorption sheet 100B, the floor surface adsorption sheet 100B is peeled off in the direction of the arrow R2 to peel off the floor surface adsorption sheet 100B from the floor surface F. This removes the floor surface adsorption sheet 100B from the floor surface F.

[0123] The step (step P5B) of preparing a long packing sheet 50 having unevenness on the first packing sheet surface 51 and the second packing sheet surface 52, and the step (step P6B) of preparing a tubular member 70 are similar to the steps P1A and P3A described in the third embodiment. Specific examples of the packing sheet 50 and the tubular member 70 are similar to the specific examples of the packing sheet 50 and the tubular member 70 described in the first embodiment.

[0124] In the step (step P7B) of placing the floor surface adsorption sheet 100B along the longitudinal direction of the packing sheet 50, as shown in FIG. 8(B), the floor surface adsorption sheet 100B is placed on the packing sheet 50 with the surface of the floor surface adsorption sheet 100B removed from the floor surface F opposite to the surface on which the adhesive layer 33 of the second base material 31 is provided facing the first packing sheet surface 51. When placing the floor surface adsorption sheet 100B on the packing sheet 50, the floor surface adsorption sheet 100B is not placed on the winding start end in the longitudinal direction (X3 direction) of the packing sheet 50, but is placed on at least a part of the packing sheet 50 except for the winding start end in the longitudinal direction. The width direction Y3 of the packing sheet 50 has a portion where the floor surface adsorption sheet 100B is placed and a portion where the floor surface adsorption sheet 100B is not placed. A specific example of the step of placing the floor surface adsorption sheet 100B is the same as the specific example described in the third embodiment. In addition, the step of rolling up only the packing sheet located at the rolling start end (step P8B) is the same as the step P5A described in the third embodiment, and the specific example of the step P8B is the same as the specific example described in the third embodiment.

[0125] In the process of storing the rolled material (process P9B), a specific example up to the process of forming the rolled material is the same as the specific example described in the third embodiment. After the rolled material is formed, it is stored. The storage location and storage period of the rolled material are set according to the purpose. When storing the rolled material, the process of storing it in the packaging box 90 described in the fourth embodiment (process P7A, process P8A, process P9A, and process P10A) may be provided, and the rolled material may be stored in the packaging form in the packaging box 90 described in the second embodiment.

[0126] When the floor surface adsorption sheet 100B is to be used again after storage, the floor surface adsorption sheet 100B with the adsorption layer 13 exposed is obtained again by a step (step P10B) of obtaining the floor surface adsorption sheet 100B with the adsorption layer 13 exposed. As shown in Fig. 8(C), the roll-shaped material is unwound, and then the packaging sheet 50 and the floor surface adsorption sheet 100B are separated to obtain the floor surface adsorption sheet 100B with the adsorption layer 13 exposed. The floor surface adsorption sheet 100B with the adsorption layer 13 exposed again is ready for use. The floor surface adsorption sheet 100B with the adsorption layer 13 exposed again is used again by a step (step P11B) of adsorbing the exposed adsorption layer 13 to the floor surface F, as shown in Fig. 7(B).

[0127] The floor surface adsorption sheet 100B is repeatedly reused by repeating the steps P4B and steps P7B to P11B. In the present embodiment, as an example, the floor surface adsorption sheet 100B can be repeatedly used 30 times or more.

[0128] (Functions and Effects of the Fifth Embodiment) According to this embodiment, it is possible to achieve the same operational effects as those (1) to (5) of the third embodiment. Furthermore, according to this embodiment, it is possible to achieve the following operational effects. (6) By achieving the same advantageous effects as those described above in (1) to (5), the floor surface adsorption sheet 100B can be used repeatedly 30 times or more, and can be easily reused. (7) For example, even if the floor surface adsorption sheet according to the present embodiment is applied to the floor surface used in a sport held in an indoor environment such as a gymnasium, the lifespan of the floor surface adsorption sheet is extended, making it possible to reuse the sheet repeatedly.

[0129] [Modifications of the embodiment] The present invention is not limited to the above-described embodiment, and any modifications or improvements that can achieve the object of the present invention are included in the present invention.

[0130] For example, in the packaging forms according to the first and second embodiments, the object to be packaged is the floor surface adsorption sheet 100, but instead of this, a floor surface adsorption sheet with a release sheet provided on the adsorption layer 13 of the floor surface adsorption sheet 100 may be packaged. Specifically, instead of the floor surface adsorption sheet 100, a floor surface adsorption sheet with a release sheet 200 as described in the fifth embodiment may be packaged. Also in the packaging methods according to the third and fourth embodiments, instead of a plurality of floor surface adsorption sheets 100A, a floor surface adsorption sheet with a release sheet provided on the adsorption layer 13 of a plurality of floor surface adsorption sheets 100A may be packaged. Even in this case, the same effects as those of (1) to (4) of the first embodiment and the same effects as those of (5) and (6) of the second embodiment can be achieved.

[0131] Furthermore, in the recycling method according to the fifth embodiment, the floor surface adhesive sheet with a release sheet prepared in step P1B may be a floor surface adhesive sheet with a release sheet in an unrolled state that has been packaged in the packaging form according to the first and second embodiments, and the packaging method according to the third and fourth embodiments.

[0132] Also, for example, in the fifth embodiment, the step P9B may store the floor surface adsorption sheet 100B in a form accommodated in a packaging box. In this case, the reuse method of the fifth embodiment may further include a step of preparing a packaging box, a step of preparing a flange having a protruding portion at the center that can be fitted into a tubular member, a step of winding the packaging sheet 50 on which the floor surface adsorption sheet 100B located at a position other than the winding start end is placed on the outer peripheral surface of the rolled packaging sheet 50 one or more times to form a roll-shaped object, a step of fitting the protruding portion into both ends of the tubular member around which the roll-shaped object is wound (i.e., the tubular member included in the roll-shaped object), and a step of storing the roll-shaped object including the tubular member with the protruding portion fitted in the packaging box.

[0133] For example, in the floor surface adsorption sheets 100, 100A, 100B described in the first to fifth embodiments, a reinforcing sheet comprising a reinforcing substrate and a reinforcing adhesive layer provided on one side of the reinforcing substrate may be attached to the end of the floor surface adsorption sheet 100, 100A, 100B. By attaching such a reinforcing sheet to the end of the floor surface adsorption sheet 100, 100A, 100B, the number of times the floor surface adsorption sheet 100, 100A, 100B can be reused increases, further extending the life of the floor surface adsorption sheet 100, 100A, 100B.

[0134] In the first to fifth embodiments, the floor surface adsorption sheets 100, 100A, 100B are smaller than the width dimension of the packing sheet 50, so the width direction of the packing sheet 50 has some areas where the floor surface adsorption sheets 100, 100A, 100B are placed and some areas where the floor surface adsorption sheets 100, 100A, 100B are not placed. This is not limiting, and when placing the floor surface adsorption sheets on the packing sheet 50, the floor surface adsorption sheets may be placed on the entire width direction of the packing sheet 50. Also, the floor surface adsorption sheets may be placed over the entire area from the middle part M to the end part E of the packing sheet in the longitudinal direction, except for the start end S of the roll. From the standpoint of preventing wrinkles in the floor surface adhesive sheet, ensuring good peelability from the packaging sheet, and preventing misalignment by winding, it is preferable not to place the floor surface adhesive sheet on the starting end S or the ending end E of the winding, but to place the floor surface adhesive sheet on the intermediate portion M which is closer to the center than both ends in the width direction of the packaging sheet 50, and which is closer to the center than the starting end S and the ending end E of the winding. EXAMPLES

[0135] The present invention will be described in more detail below with reference to examples, but the present invention is not limited to these examples in any way.

[0136] <Example 1> First, an adhesive sheet body with a release sheet was prepared (Yupo Corporation, Yupo (registered trademark) Suction Tac (registered trademark) Outdoor, model number "WKO280"). The adhesive sheet body with a release sheet is a sheet in which a synthetic paper containing a polypropylene resin as a first base material, an adhesive layer, and a first release sheet are laminated in this order. Then, a pattern was printed on the surface of the synthetic paper of the adhesive sheet with an inkjet printer to form a printed layer as a decorative layer.

[0137] Next, a protective sheet with a release sheet (manufactured by Lintec Corporation, product name "LAG Protect M-093PN200") was prepared. The protective sheet was a sheet in which a second substrate, an adhesive layer, and a second release sheet were laminated in this order. The second substrate contained a polyvinyl chloride resin. The adhesive layer contained an acrylic adhesive. The second release sheet had a release layer treated with a silicone release agent on the surface of the polyethylene resin layer of the double-sided polyethylene resin laminated paper.

[0138] Next, the second release sheet was peeled off from the protective sheet with release sheet to expose the adhesive layer to form a protective sheet, and the exposed adhesive layer of the protective sheet was superimposed and pressed onto the decorative layer formed on the main body of the adhesive sheet with release sheet. In this way, a floor adhesive sheet with release sheet was produced in which the first release sheet, adhesive layer, first substrate, decorative layer, adhesive layer, and second substrate were laminated in this order. This operation was repeated to produce multiple floor adhesive sheets with release sheets.

[0139] Next, the first release sheet was peeled off from each of the plurality of floor surface adhesive sheets with release sheets prepared above to obtain floor surface adhesive sheets with the adhesive layer exposed. After that, the exposed adhesive layer of the floor surface adhesive sheet was attached to the floor surface.

[0140] Next, a packaging sheet (polyester cloth manufactured by Nip Corporation, product name "NBS1816") was prepared. A 3-inch paper tube was also prepared. Furthermore, a resin flange with a protruding portion in the center and a cardboard packaging box were prepared.

[0141] After all the floor surface adhesive sheets were attached to the floor surface, the floor surface adhesive sheets were peeled off from the floor surface in order. The multiple floor surface adhesive sheets peeled off from the floor surface were placed on the middle part of the packaging sheet, excluding the winding start end and the winding end, along the longitudinal direction of the packaging sheet. When placing the multiple floor surface adhesive sheets on the packaging sheet, the second base material of the floor surface adhesive sheet was placed facing the packaging sheet, and the adsorption layer was placed facing upwards, with the adjacent floor surface adhesive sheets spaced apart from each other, within the range of the width direction of the packaging sheet and closer to the center than both ends in the width direction of the packaging sheet. In this state, when a roll-shaped product is formed with the floor surface adhesive sheet placed on the packaging sheet, the packaging sheet is on the outer peripheral surface side, and the floor surface adhesive sheet is on the core side. Next, with the floor surface adhesive sheet placed on the packaging sheet, a 3-inch paper tube was placed facing the winding start end, and only the packaging sheet was wound once. Then, the packing sheet with the floor surface adsorption sheet placed thereon was wound around the outer periphery of the packing sheet wound around a 3-inch paper tube to form a roll-shaped product. The roll-shaped product was then secured with a rubber tightening band.

[0142] Next, the flange protrusions were fitted into both ends of a 3-inch paper tube of the rolled product to form a rolled product with flanges. This rolled product with flanges was stored in a packaging box.

[0143] After storage, the rolled product with flanges was removed from the packaging box, the flanges were removed by pulling the protruding parts of the flanges out from both ends of the 3-inch cardboard core, and the fastening bands were removed to obtain a rolled product. After unwinding this rolled product, multiple floor surface adsorption sheets were taken out from the packaging sheet and the adsorption surfaces of the floor surface adsorption sheets were attached to the floor surface. This procedure of attaching the adsorption surfaces of the floor surface adsorption sheets to the floor surface, peeling the adsorption surfaces of the floor surface adsorption sheets from the floor surface, packaging and storage, and attaching the adsorption surfaces of the floor surface adsorption sheets to the floor surface again was repeated 30 times.

[0144] <Comparative Example 1> In Example 1, except for the following points, the same procedure as in Example 1 was followed: the adhesive surface of the floor surface adhesive sheet was attached to the floor surface, the adhesive surface of the floor surface adhesive sheet was peeled off from the floor surface, then packaged and stored, and the adhesive surface of the floor surface adhesive sheet was attached again to the floor surface. This operation was repeated 30 times. As the packaging sheet, instead of polyester cloth, a release paper with a release agent layer treated with a silicone-based release agent on one side of the paper base material was prepared. When forming a roll-shaped product with the floor surface adsorption sheet placed on the release sheet, the second base material of the floor surface adsorption sheet was placed opposite the paper base material of the release paper so that the packaging sheet was on the outer peripheral surface side and the floor surface adsorption sheet was on the core side, and the floor surface adsorption sheet was placed so that the adsorption layer was facing up.

[0145] <Comparative Example 2> In Example 1, the orientation of the multiple floor surface adsorption sheets placed on the packaging sheet was reversed. That is, except that adjacent floor surface adsorption sheets were placed at a distance from each other with the adsorption layer facing the packaging sheet and the second base material facing upward, the adsorption surfaces of the floor surface adsorption sheets were attached to the floor surface in the same manner as in Example 1, the adsorption surfaces of the floor surface adsorption sheets were peeled off from the floor surface, packaged and stored, and the adsorption surfaces of the floor surface adsorption sheets were attached to the floor surface again. This operation was repeated 30 times.

[0146] As a result of Example 1, even when the operation of attaching the adsorption surface of the floor surface adhesive sheet to a floor surface, peeling it off from the floor surface, packaging and storing it, and attaching the adsorption surface of the floor surface adhesive sheet to the floor surface again was repeated 30 times, there was little meandering in the rolled product when it was formed. Even if meandering occurred, it was easy to correct. Furthermore, no wrinkles were observed in the floor surface adhesive sheet. Furthermore, after unwinding the rolled product, the floor surface adhesive sheet could be easily peeled off from the packaging sheet when removing it from the packaging sheet.

[0147] As a result of Comparative Example 1, the adsorption surface of the floor surface adsorption sheet was attached to the floor surface, the adsorption surface of the floor surface adsorption sheet was peeled off from the floor surface, the adsorption surface of the floor surface adsorption sheet was packed and stored, and the adsorption surface of the floor surface adsorption sheet was attached to the floor surface again. After repeating this operation 30 times, wrinkles were observed in the floor surface adsorption sheet. In addition, when the roll-shaped product was formed, the roll-shaped product frequently meandered. In addition, when meandering occurred, it was difficult to correct the meandering. Furthermore, after unwinding the roll-shaped product, it was difficult to peel the floor surface adsorption sheet from the packaging sheet when removing it from the packaging sheet.

[0148] As a result of Comparative Example 2, the phenomenon of interlayer delamination occurred in the floor surface adhesive sheet after the operation of attaching the adhesive surface of the floor surface adhesive sheet to the floor surface, peeling it off from the floor surface, packaging and storing it, and then attaching the adhesive surface of the floor surface adhesive sheet to the floor surface again was repeated 30 times. In addition, after unwinding the roll-shaped product, it was difficult to peel the floor surface adhesive sheet from the packaging sheet when removing it from the packaging sheet.

[0149] From the above results, it was found that the packaging form, packaging method, and reuse method which are one aspect of the present invention suppress the occurrence of wrinkles in the floor surface adhesive sheet, provide good peelability from the packaging sheet, and suppress the occurrence of winding misalignment.
