Description

[Technical field]

[0001] The present invention relates to a multi-packaged paper product comprising a plurality of individually wrapped paper products packaged in an exterior film. [Background technology]

[0002] Conventionally, thin paper such as tissue paper is stored in a stacked state in a stiff paper carton and sold as a product.

[0003] However, in recent years, many products are sold in soft packs made of film.

[0004] The most common packaging form for such soft pack tissues is caramel packaging, but gusset packaging or pillow packaging may also be used from the standpoint of cost and productivity.

[0005] Furthermore, there are many products in which a plurality of such soft pack tissues are bundled together in an outer gusset packaging. At that time, there is also a technique of packaging with the longitudinal direction of the tissue and the up-down direction of the gusset packaging approximately parallel (hereinafter also referred to as vertical insertion).In this case, the top and bottom surfaces of the stacked soft pack tissues are sandwiched and pushed out, and then packaged in an outer packaging, so it is easier to sandwich multiple soft pack tissues and has excellent operability than packaging with the longitudinal direction of the tissue and the up-down direction of the gusset packaging approximately at right angles (hereinafter also referred to as horizontal insertion).

[0006] For example, Patent Document 1 discloses a film-wrapped tissue assembly package in which a plurality of film-wrapped tissues are stored in a gusset packaging bag, the film-wrapped tissues being formed by covering a tissue paper bundle, which is made by folding a plurality of tissue papers in a pop-up style, with a packaging film, the longitudinal direction of the plurality of film-wrapped tissues being arranged along the vertical direction of the gusset packaging bag, the first surface of the film-wrapped tissues being opposed to the second surface of the film-wrapped tissue adjacent to the film-wrapped tissue being arranged in the left-right direction of the gusset packaging bag, one side surface of the film-wrapped tissue in the longitudinal direction being opposed to the top surface of the gusset packaging bag, The other longitudinal side surface of the tissue is placed opposite the bottom surface of a gusset packaging bag, and one side surface and the other side surface are formed by folding the packaging film into a caramel wrap, forming the film-wrapped tissue collective package with a compression ratio of 85 to 100%, and the compression ratio of the film-wrapped tissue collective package is calculated by dividing the left-to-right lengths of the first surface of the leftmost film-wrapped tissue and the second surface of the rightmost film-wrapped tissue to be inserted into the film-wrapped tissue collective package by the left-to-right lengths of the left and right surfaces of the film-wrapped tissue collective package into which the film-wrapped tissue is inserted, and multiplying the value obtained by this calculation by 100.

[0007] Patent Document 2 discloses a pocket tissue package in which a number of pocket tissues, each having a three-dimensional shape with roughly rectangular top and bottom surfaces and long and short side edges connecting them, are arranged in a row with their top and bottom surfaces butted together to form an array of pocket tissues that is roughly rectangular in shape overall, and which is then wrapped in film with an exterior film in contact with each face of the array, so that the side where one of the short sides of each pocket tissue is lined up is the bottom face and the side where the other short side edge is lined up is the top face, and a continuous circular or U-shaped perforation line for opening is formed along the edge of the top face.

[0008] [Patent Document 1] Patent No. 7336342 [Patent Document 2] JP 2013-028401 A Summary of the Invention [Problem to be solved by the invention]

[0009] However, when gusset-packaged or pillow-packaged softpack tissues are inserted vertically into the exterior of a gusset package, if the film pitch length (the length from one end of the individual packaging film of the softpack tissues to the other end of the tissue laminate when the tissue laminate is removed) is not appropriate for the longitudinal dimension of the tissue laminate, the aesthetic appeal and productivity of the product may decrease, and the aesthetic appeal of the individual packaging film and internal sheets may also decrease.

[0010] Furthermore, if the perimeter of the individual wrapping film in the width direction is not appropriate for the perimeter of the tissue laminate in the same direction, the cosmetic appearance and operability of the product (exterior packaging and soft-pack tissue) may decrease, and the cosmetic appearance of the internal tissue paper may also decrease.

[0011] The present invention has been made in consideration of the above circumstances, and has an object to provide a multi-packaged paper product product in which a plurality of individually wrapped paper product pieces, each of which is made by individually wrapping a tissue laminate in a film using gusset packaging or pillow packaging, are gusset-packaged in an exterior film, which makes it easy to wrap the tissue laminate and to insert the individually wrapped paper product pieces into the exterior film, and which has excellent productivity and aesthetic appeal.

[Figure 4] FIG. 3 is a perspective view showing a method for measuring the film pitch length of the individual packaging film shown in FIG. 2. [Diagram 5] 1 is a perspective view showing an example of a paper product packaged in the paper product package of the present invention. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Hereinafter, the form for carrying out the present invention (hereinafter, the embodiment) will be described in detail with reference to the drawings. However, these are presented for the purpose of illustration only and are not intended to limit the present invention. In the specification, the longitudinal direction and the width direction respectively refer to the direction of the production line (also referred to as the conveying direction or MD direction) and the direction perpendicular to the production line direction (also referred to as the CD direction) during the production of the paper product packaging body, and the height direction refers to the direction perpendicular to both the longitudinal direction and the width direction.

[0024] <Multi-packaging for paper products> FIG. 1 is a perspective view showing an example of a multi-package of paper products according to the present invention (hereinafter, simply referred to as "multi-package"). As shown in FIG. 1, the multi-package 1 of the present invention is a package in which a plurality of individual paper product packages 10 are packaged in an exterior film. Examples of resin films used for the exterior film include LDPE (low density polyethylene), LLDPE (linear low density polyethylene), HDPE (high density polyethylene), CPP (unoriented polypropylene), milky PE (polyethylene), and films in which these materials are blended or mixed. In addition, these films may be laminated, coated, or multi-layered with different materials. Examples of the different materials include OPP (oriented polypropylene), EVOH (ethylene vinyl alcohol copolymer), Ny (nylon), PET (polyethylene terephthalate), and PVDC (polyvinylidene chloride). Among these, LDPE (low density polyethylene), LLDPE (linear low density polyethylene), and HDPE (high density polyethylene) are preferred. By using PE, which has extensibility and high strength, it is possible to create a film into which multiple individual paper product packages 10 as in the present application can be easily inserted.

[0025] The number of the individual paper product packages 10 wrapped in the exterior film is preferably 3 to 8. If the number is less than 3, the individual paper product packages 10 move inside the gusset packaging bag 30, resulting in poor cosmetic appearance. If the number is more than 8, the individual paper product packages 10 are compressed inside the gusset packaging bag 30, causing the exterior film and the individual packaging film 20 to tear, and the tissue paper to fold or wrinkle, resulting in poor cosmetic appearance. The lower limit of the number of individual paper product packages 10 wrapped in an exterior film is more preferably 4 or more, and even more preferably 5 or more. The upper limit is more preferably 7 or less, and even more preferably 6 or less.

[0026] At this time, as shown in Fig. 1, the individual paper product packages 10 are arranged (i.e., inserted vertically) so that their longitudinal direction is approximately parallel to the up-down direction of the gusset packaging bag 30 formed from an exterior film and having a handle 37 at the upper end. If the packaging bag formed from an exterior film is caramel-wrapped, it is difficult to hold the entire individual paper product package 10 that wraps the soft tissue laminate 21 when sealing it by heat sealing, which leads to packaging defects and poor productivity. Note that, as shown in Fig. 1, the handle 37 is preferably provided with a finger hole 38.

[0027] The individual paper product packages 10 are arranged in the left-right direction of the gusset packaging bag 30 so that the top surface of one individual paper product package 10 faces the bottom surface of another individual paper product package 10 adjacent to the one individual paper product package 10. That is, a plurality of individual paper product packages 10 are stacked between the left side surface 35 and the right side surface 36 of the gusset packaging bag 30 shown in Fig. 1. In this state, the individual paper product packages 10 are arranged so that one side surface in the width direction faces the front surface 33 of the gusset packaging bag 30 and the other side surface in the width direction faces the back surface 34 of the gusset packaging bag 30. Furthermore, the individual paper product packages 10 are arranged so that one longitudinal side of one individual paper product package 10 faces the top surface 31 of the gusset packaging bag 30 and the other longitudinal side face faces the bottom surface 32 of the gusset packaging bag 30, or are arranged in the vertical direction of the gusset packaging bag 30 so that one longitudinal side of one individual paper product package 10 faces the other longitudinal side of another individual paper product package 10 adjacent to the one individual paper product package 10.However, it is preferable that one longitudinal side of one individual paper product package 10 faces the top surface 31 of the gusset packaging bag 30 and the other longitudinal side face faces the bottom surface 32 of the gusset packaging bag 30 as shown in Figure 1 (i.e., only one layer of individual paper product packages 10 is arranged in the vertical direction of the gusset packaging bag 30). It is preferable that the bottom surface 32 of the gusset packaging bag 30 is sealed by heat sealing after the multiple individual paper product packages 10 are inserted.

[0028] The thickness of the exterior film forming the gusset packaging bag 30 is preferably 20 μm or more and 60 μm or less. If the thickness is less than 20 μm, the exterior film is easily torn, resulting in poor aesthetics and productivity. If the thickness exceeds 60 μm, the exterior film is difficult to heat seal, resulting in poor productivity. The thickness of the exterior film is preferably 25 μm or more, more preferably 30 μm or more, and more preferably 55 μm or less, and more preferably 50 μm or less. The thickness of the exterior film can be measured in accordance with JIS K7130.

[0029] <Individual packaging of paper products> Fig. 2 is a perspective view showing an example of an individual packaged paper product of the present invention (hereinafter also simply referred to as "individual package") and a paper product. As shown in Fig. 2, the individual packaged paper product 10 of the present invention is an individual packaging film 20 having four mountain folds 22 extending in one direction that are approximately parallel to each other, which entirely covers a tissue laminate 21, which is a paper product, and the tissue laminate 21 is sealed by two or more heat seal parts. In the individual package 10 in which the tissue laminate 21 is packaged in gusset packaging as shown in FIG. 2, the heat-sealed portion includes a pair of end-side heat-sealed portions 23 that seal the tissue laminate 21 at both longitudinal ends of the individual packaging film 20, but in FIG. 3, which shows another example of an individual paper product package and a paper product, the tissue laminate 21 is packaged using pillow packaging, so the heat-sealed portion includes not only the end-side heat-sealed portions 23 but also the heat-sealed portions 230 of the pillow packaging. Moreover, the mountain folds 22 may not have any lines, but preferably have lines and are creased along the lines, similar to the valley folds 24 described below. The length of each line may be a part of the mountain folds 22, and is preferably 50% or more, more preferably 60% or more, and even more preferably 70% or more.

[0030] As shown in Fig. 2, the individual packaging film 20 preferably has two valley folds 24 extending in the same direction and generally parallel to the mountain folds 22. The valley folds 24 are preferably formed so as to connect an end of one end heat-sealed portion 23 to an end of the other end heat-sealed portion 23. Each valley fold 14 preferably has a crease and is creased along the crease. The length of each crease may be a part of the valley fold 14, and is preferably 50% or more, more preferably 60% or more, and even more preferably 70% or more.

[0031] Furthermore, the individual paper product package 10 preferably includes a perforation 25 for removing the tissue paper (one sheet constituting the tissue laminate 21). That is, the individual packaging film 20 has a single line perforation 25 for forming an opening for removing the tissue paper, and the opening is formed by cutting the perforation 25 and opening the package when in use. It is preferable that the opening is formed by cutting the perforation 25 and opening the package when in use, but the perforation is not limited to one line as long as the tissue paper can be removed. The required number of tissue papers can be obtained by sequentially pulling out (removing) the tissue paper from the opening that has been formed. The perforation 25 is preferably provided on the surface of the individual wrapping film 20 that covers the top of the tissue stack 21 so as to be approximately parallel to one side of the tissue paper. It is also preferable that the perforation is provided so as to be located above the center of the tissue stack 21. As mentioned above, the number of perforations does not have to be one.

[0032] (Individually wrapped film) When the individual paper product package 10 is a gusset package as shown in Fig. 2, the individual packaging film 20 is preferably a tube-type film that contains at least a film base material. The individual packaging film 20 preferably does not contain paper, and is preferably printed on. By using the individual packaging film 20 with folds made of a tube-type film and appropriately performing heat sealing under the conditions described below, the tightness of the individual packaging body 10 can be ensured and the cosmetic appearance can be improved when the tissue laminate 21 is packaged. The tube-type film is a film obtained by forming a sheet-like film into a cylindrical shape like a tube. When the individual packaging body 10 is a pillow package as shown in Fig. 3, the individual packaging film 20 is preferably not a tube-type film, and since the tissue laminate 21 is wrapped and sealed while the individual packaging film 20 is being formed into a cylindrical shape, the individual packaging film 20 is preferably a raw roll film (flat raw film) type.

[0033] The individual packaging film 20 may be a single layer or multiple layers, but a single layer is preferable from the viewpoint of productivity due to ease of heat sealing. In this case, the layer refers to the film layer, and other layers described later are not counted in the number of layers.

[0034] The material of the film forming each layer can be any plastic (thermoplastic resin) film used for packaging ordinary paper products without any particular limitation. Examples of the material of the plastic film include conventionally known thermoplastic resins such as polyolefin (polyethylene, polypropylene, etc.), polyester (PET, etc.), polyamide (nylon, etc.), polycarbonate, polystyrene, polyvinyl chloride, etc., and preferably polyethylene. As a specific configuration, when the film is formed as a single layer, the material of the film is preferably LDPE (low density polyethylene), LLDPE (linear low density polyethylene), HDPE (high density polyethylene), CPP (unoriented polypropylene), milky PE (polyethylene), or a film in which these materials are blended or mixed. In addition, these films may be laminated, coated, or multi-layered with different materials to form a multi-layer film. Examples of the different materials include OPP (oriented polypropylene), EVOH (ethylene vinyl alcohol copolymer), Ny (nylon), PET (polyethylene terephthalate), and PVDC (polyvinylidene chloride). Among these, LDPE (low density polyethylene), LLDPE (linear low density polyethylene), and HDPE (high density polyethylene) are preferred. By using PE, which has stretchability and high strength, a film that is easy to wrap the tissue laminate 21 of the present application can be obtained.

[0035] The method for matt-finishing the film is not particularly limited, and may be a conventionally known method, a method for pressing the surface of a tubular film against an embossing roll or a matte roll to impart irregularities, or a method for imparting irregularities by sandblasting. These methods may be performed during the molding of the tubular film, but when the film is formed in a multilayer, it is preferable to perform the method on a single layer of polyethylene to obtain a matt-finished polyethylene film, and then extrusion laminate the innermost layer of a milky white polyethylene film or the like. Alternatively, for example, a method using a polymer blend or a method of biaxially stretching a laminate of a polyolefin resin blend may be used without performing surface treatment as described above.

[0036] Furthermore, the individual packaging film 20 of the present invention may have other layers in addition to the film layer. Examples of the other layers include a water vapor barrier layer, an oxygen barrier layer, a print layer, a printability improving layer, an overprint layer, a light-shielding layer, etc. These other layers can be provided, for example, on the surface in contact with the tissue laminate 21 or on the surface exposed to the outside air.

[0037] The basis weight of the individual packaging film 20 is 25 g / m 2 It is preferable that the weight is 33 g / m or more. 2 More preferably, it is 40 g / m or more. 2 More preferably, the upper limit is 85 g / m or more. 2 Preferably, it is 63 g / m or less. 2 More preferably, it is 50 g / m or less. 2 It is even more preferable that: The basis weight of the individual packaging film 20 is 25 g / m 2 If the basis weight is less than 85 g / m, the individual packaging film 20 is easily torn, and the cosmetic appearance and productivity are poor. 2 If the thickness exceeds the above range, the individual packaging film 20 becomes too thick, making heat sealing difficult and reducing productivity. The basis weight of the individual packaging film 20 can be measured in accordance with JIS P 8124.

[0038] The thickness of the individual packaging film 20 of the present invention is preferably 20 μm or more and 70 μm or less. If the thickness is less than 20 μm, the individual packaging film 20 is easily torn, and the cosmetic appearance and productivity are poor. If the thickness exceeds 70 μm, the individual packaging film 20 is difficult to heat seal, and the productivity is poor. The lower limit of the thickness of the individual packaging film 20 is more preferably 25 μm or more, and even more preferably 30 μm or more. The upper limit is more preferably 60 μm or less, and even more preferably 50 μm or less. The thickness of the individual packaging film 20 can be measured in accordance with JIS K7130.

[0039] In addition, the lower limit of the film circumference (D) of the individual packaging film 20 in the width direction of the individual paper product package 10 of the present invention is preferably 252 mm or more, more preferably 262 mm or more, and even more preferably 272 mm or more. The upper limit is preferably 332 mm or less, more preferably 322 mm or less, and even more preferably 315 mm or less. When the width direction circumference (C) of the tissue laminate 21 does not change, if the film circumference (D) of the individual packaging film 20 in the width direction is less than 252 mm, the individual packaging body 10 is too tight, causing the tissue paper to fold or wrinkle, resulting in poor cosmetic appearance. In addition, the tissue laminate 21 is also poorly packaged in the individual packaging film 20. If the film circumference (D) of the individual packaging film 20 in the width direction exceeds 332 mm, the side of the individual packaging film 20 will swell significantly when it is sandwiched by the guide of the device for insertion into the exterior film, resulting in poor ease of insertion into the exterior film. The film circumference (D) of the individual packaging film 20 can be measured with a ruler after cutting the individual packaging film 20. The width direction of the individual packaging body 10 is the direction along the CD direction of the individual packaging film 20. In addition, when the individual packaging body 10 is a pillow package as shown in Fig. 3, the portion where the individual packaging film 20 overlaps in the heat seal portion 230 of the pillow package is not included in the film circumference.

[0040] Furthermore, the lower limit of the film pitch length (B) in the individual packaging film 20 is preferably 190 mm or more, more preferably 200 mm or more, and even more preferably 210 mm or more. The upper limit is preferably 250 mm or less, more preferably 240 mm or less, and even more preferably 230 mm or less. When the longitudinal dimension of the tissue laminate 21 does not change, if the film pitch length (B) is less than 190 mm, the tightness of the individual packaging body 10 is too high, causing the tissue paper to fold or wrinkle, resulting in poor cosmetic appearance. In addition, the width of the heat seal at the heat seal parts 23 on both ends cannot be stably secured, resulting in poor productivity. If the film pitch length (B) exceeds 250 mm, the tightness of the individual packaging body 10 is too low, causing the tissue laminate 21 to move inside the individual packaging film 20, causing the tissue paper to fold or wrinkle, resulting in poor cosmetic appearance. In addition, the width HW of the individual packaging edge portion is rolled in during the heat seal on the bottom surface 32 of the gusset packaging bag 30, resulting in poor productivity. The film pitch length (B) in the individual packaging film 20 is the length from one end of the individual packaging film 20 of the individual paper product package 10 when the tissue laminate 21 is removed, and is measured with the tissue laminate 21 removed from the individual packaging film 20 and the mountain folds 22 of the top and bottom surfaces aligned and folded, as shown in Figure 4.

[0041] (Heat seal part) The two or more heat-sealed portions provided in the individual paper product package 10 of the present invention are for sealing the paper product 11. Note that the above-mentioned heat-sealed portions 23 on both end sides will be mainly described here. Both end side heat-sealed portions 23 are formed at the ends of mountain fold portion 22 in substantially straight lines perpendicular to the direction of mountain fold portion 22 and substantially parallel to each other. Both end side heat-sealed portions 23 may be formed in such a way that heat-sealed portions and non-heat-sealed portions are alternately formed (dotted lines) as shown in Fig. 2, but may also be formed in such a way that heat-sealed portions are uniformly formed (straight lines), that heat-sealed portions are formed in a lattice pattern, or that heat-sealed portions are formed as multiple straight lines.

[0042] In this case, the distance (width of the individual packaging ear) HW from the end of one of the individual packaging films 20 to the closest heat-sealed portions 23 on both ends as shown in Fig. 2 is preferably 3 mm or more and 20 mm or less. If the width HW of the individual packaging ear is less than 3 mm, the heat-sealed portion and the cut portion of the individual packaging film 20 are too close to each other, resulting in poor packaging and poor productivity. If the width HW of the individual packaging ear is more than 20 mm, the width HW of the individual packaging ear is bent or crushed when inserted into the exterior film, resulting in poor cosmetic appearance of the multi-package 1 and the individual packaging 10. The width HW of the individual packaging ear portion is more preferably 5 mm or more, and even more preferably 7 mm or more, and more preferably 16 mm or less, and even more preferably 13 mm or less. The width HW of the individual packaging ear portion is measured using a ruler at four points from the left and right ends of the individual packaging body 1 to the closest heat-sealed portions 23 on both ends, and the average of the measured values ​​is taken as the measured value.

[0043] In addition, the lower limit of the heat seal distance (E) from the end of one end heat seal portion 23 to the end of the other end heat seal portion 23 in the individual packaging film 20 is preferably 170 mm or more, more preferably 180 mm or more, and even more preferably 190 mm or more. The upper limit is preferably 224 mm or less, more preferably 218 mm or less, and even more preferably 210 mm or less. When the longitudinal dimension of the tissue laminate 21 does not change, if the heat seal distance (E) is less than 170 mm, the individual package 10 is too tight and the tissue paper is folded or wrinkled, resulting in poor cosmetic appearance. If the heat seal distance (E) exceeds 224 mm, the individual package 10 is too loose and the tissue laminate 21 moves inside the individual packaging film 20, resulting in poor cosmetic appearance. The heat-seal distance (E) from the end of the heat-sealed portion 23 at one end of the individual packaging film 20 to the end of the heat-sealed portion 23 at the other end of the individual packaging film 20 means the dimension when the tissue laminate 21 is packaged in the individual packaging film 20.

[0044] The heat seal distance (E) is measured by first pinching the center of one end heat seal part 23 in the width direction with one hand and lifting up the entire individual package 10 (at this time, the tissue laminate 21 in the individual packaging film 20 is lowered by its own weight to the other end heat seal part 23, i.e., the lower end heat seal part 23 in the lifted state, and the individual packaging film 20 is in a taut state). Then, the distance from one end heat seal part 23 to the other end heat seal part 23 is measured with a ruler. The measurement is also performed at the ends of the end heat seal parts 23 in the width direction, and the average of the values ​​at both ends (i.e., two points) is taken as the heat seal distance (E).

[0045] (Packaging form) The packaging form of the individual paper product packages 10 according to the present invention is gusset packaging or pillow packaging. If the packaging form is caramel packaging, it is difficult to press the entire package with the soft tissue laminate 21 when sealing with heat sealing, which leads to packaging defects and is therefore poor in productivity.

[0046] Gusset packaging is a packaging format in which the base material is formed into a cylindrical shape with both ends of the bottom or mouth folded inward to match the length (height) of the bag, one side of which is sealed by heat sealing or the like, and the packaged item is inserted into the inside of the base material through an insertion opening, sealed horizontally by heat sealing or the like, and cut into individual bags at this sealed part. This gusset packaging can be performed using a known device. The packaged item may also be inserted in a state where the base material at the insertion opening is turned outward so as not to be rolled inward.

[0047] Pillow packaging is a packaging format in which the packaging substrate is overlapped at both ends in the width direction with the inner surfaces facing each other so as to encase the packaged item placed on or under a sheet-like packaging substrate into a cylindrical shape, and the overlapped part is formed into a cylindrical shape by heat sealing or the like, and the bottom part or the mouth part is sealed in a horizontal line by heat sealing or the like to match the length (height) of the bag, and the sealed part is cut into individual bags. This pillow packaging can be performed using a known device. There are two types of pillow packaging: vertical pillow packaging, in which the packaging base is fed vertically and the packaged item is filled from above while being wrapped, and horizontal pillow packaging, in which the packaging base is fed horizontally and the packaged item is wrapped. When packaging tissue paper, horizontal pillow packaging is preferred from the perspective of packaging speed and the shape of the tissue paper.

[0048] (Tissue laminate) 5 is a perspective view showing an example of a tissue laminate 21 (laminated with tissue paper, which is thin paper) packaged in the individual paper product package 10 of the present invention. The individual paper product package 10 of the present invention is particularly suitable for packaging soft paper products such as tissue paper. The tissue paper may be one ply or two ply, but two ply is preferred. The tissue paper is preferably general tissue paper, not lotion tissue paper containing lotion liquid. By using general tissue paper, it is possible to obtain a tissue laminate having excellent cosmetic properties as in the present application.

[0049] Although there is no particular limitation on the way the tissue papers included in the tissue stack 21 are folded, it is preferable that they are stacked in a V-fold. By folding in a V-shape, it is possible to produce a package in which the upper and lower parts of the tissue stack 21 are less likely to turn over during packaging. The processing machine used for folding in a V-shape may be either an interfolder or a multi-stand type interfolder, but a multi-stand type interfolder is preferable.

[0050] (Dimensions of tissue laminate) The lower limit of the width of the tissue stack 21 is preferably 80 mm or more, more preferably 90 mm or more, and even more preferably 95 mm or more. The upper limit is preferably 120 mm or less, more preferably 115 mm or less, and even more preferably 110 mm or less. When the film circumference (D) of the individual packaging film 20 in the width direction does not change, if the dimension of the tissue laminate 21 in the width direction is less than 80 mm, the tightness of the individual packaging body 10 is too low and the tissue laminate 21 moves inside the individual packaging film 20, causing the tissue paper to fold and wrinkle, resulting in poor cosmetic appearance. If the dimension of the tissue laminate 21 in the width direction exceeds 120 mm, the tightness of the individual packaging body 10 is too high and the tissue paper to fold and wrinkle, resulting in poor cosmetic appearance. In addition, the tissue laminate 21 is also less easy to wrap in the individual packaging film 20. The width dimension of the tissue laminate 21 can be measured as follows. The individual packaging film 20 of the individual package 10 is cut, and the tissue laminate 21 is gently removed. A 30 cm ruler (Silver straight scale JIS Class 1, stainless steel, 64 g, manufactured by Shinwa Sokutei Co., Ltd.) is placed on the top surface of the tissue laminate 21 along the width direction of the tissue laminate 21, and the length of the top surface is measured. The width dimension of the tissue laminate 21 is measured at four points using this method, and the average is taken as the measured value.

[0051] The lower limit of the longitudinal dimension (A) of the tissue stack 21 is preferably 120 mm or more, more preferably 130 mm or more, and even more preferably 150 mm or more. The upper limit is preferably 220 mm or less, more preferably 200 mm or less, and even more preferably 185 mm or less. When the film pitch length (B) and the distance between heat seals (E) in the individual packaging film 20 do not change, if the longitudinal dimension (A) of the tissue laminate 21 is less than 120 mm, the tightness of the individual packaging body 10 is too low and the tissue laminate 21 moves inside the individual packaging film 20, causing the tissue paper to fold and wrinkle, resulting in poor cosmetic appearance. If the longitudinal dimension (A) of the tissue laminate 21 exceeds 220 mm, the tightness of the individual packaging body 10 is too high and the tissue paper to fold and wrinkle, resulting in poor cosmetic appearance. In addition, the width of the heat seal at the heat seal parts 23 on both ends cannot be stably secured, resulting in poor productivity. The longitudinal dimension (A) of the tissue laminate 21 can be measured as follows. The individual packaging film 20 of the individual package 10 is cut, and the tissue laminate 21 is gently removed. A 30 cm ruler (Shinwa Sokutei Co., Ltd., straight silver, JIS Class 1, stainless steel, 64 g) is placed on the top surface of the tissue laminate 21 along the longitudinal direction of the tissue laminate 21, and the length of the top surface is measured. The longitudinal dimension of the tissue laminate 21 is measured at four points using this method, and the average is taken as the measured value.

[0052] The ratio (B / A×100(%)) of the film pitch length (B) of the individual packaging film 20 to the longitudinal dimension (A) of the tissue laminate 21 is 119% or more and 161% or less. If the ratio is less than 119%, the tightness of the individual packaging body 10 is too high, causing the tissue paper to fold or wrinkle, resulting in poor cosmetic appearance. In addition, the width of the heat seal at the heat seal parts 23 on both ends cannot be stably secured, resulting in poor productivity. If the ratio exceeds 161%, the tightness of the individual packaging body 10 is too low, causing the tissue laminate 21 to move inside the individual packaging film 20, causing the tissue paper to fold or wrinkle, resulting in poor cosmetic appearance. In addition, the width HW of the individual packaging ear part is rolled in the heat seal at the bottom surface 32 of the gusset packaging bag 30, resulting in poor productivity. The ratio (B / A×100(%)) of the film pitch length (B) of the individual packaging film 20 to the longitudinal dimension (A) of the tissue laminate 21 is preferably 125% or more, more preferably 131% or more, and more preferably 150% or less, and more preferably 144% or less.

[0053] In addition, the ratio (E / A×100(%)) of the heat-sealed dimension (E) from one end of the heat-sealed part 23 to the other end of the heat-sealed part 23 at both ends to the longitudinal dimension (A) of the tissue laminate 21 is preferably 106% or more and 144% or less. If the ratio is less than 106%, the tightness of the individual package 10 is too high, causing the tissue paper to fold or wrinkle, resulting in poor cosmetic appearance. If the ratio exceeds 144%, the tightness of the individual package 10 is too low, causing the tissue laminate 21 to move inside the individual packaging film 20, causing the tissue paper to fold or wrinkle, resulting in poor cosmetic appearance. The ratio (E / A×100(%)) of the heat-sealed dimension (E) from one end of the heat-sealed part 23 at both ends 23 to the longitudinal dimension (A) of the tissue laminate 21 is preferably 113% or more, more preferably 120% or more, and more preferably 138% or less, and more preferably 130% or less.

[0054] Furthermore, the lower limit of the height of the tissue stack 21 is preferably 34 mm or more, more preferably 37 mm or more, and even more preferably 38 mm or more, and the upper limit is preferably 80 mm or less, more preferably 70 mm or less, and even more preferably 45 mm or less. When the film circumference (D) of the individual packaging film 20 in the width direction does not change, if the height of the tissue laminate 21 is less than 34 mm, the sides of the individual packaging film 20 will swell significantly when clamped by the guides of the device for insertion into the exterior film, making it less easy to insert into the exterior film. If the height of the tissue laminate 21 exceeds 80 mm, the individual packaging body 10 will be too tight, causing the tissue paper to fold or wrinkle, resulting in poor cosmetic appearance. In addition, the tissue laminate 21 will be less easy to wrap in the individual packaging film 20. The height of the tissue laminate 21 can be measured as follows. The individual packaging film 20 of the individual package 10 is cut, and the tissue laminate 21 is gently removed. A sample tissue laminate 21 is placed on a horizontal stand, and a 30 cm ruler is placed on the top surface of the tissue laminate 21 parallel to the width direction, and the tissue laminate is stood vertically on the horizontal stand so that the ruler is perpendicular to a 30 cm ruler (Shinwa Sokutei Co., Ltd., silver straight scale, JIS Class 1, stainless steel, 64 g), and the height is measured. Four points are measured in this manner, and the average is taken as the measured value.

[0055] The lower limit of the widthwise perimeter (C) of the tissue stack 21 is preferably 250 mm or more, more preferably 260 mm or more, and even more preferably 266 mm or more. The upper limit is preferably 340 mm or less, more preferably 320 mm or less, and even more preferably 290 mm or less. When the film circumference (D) of the individual packaging film 20 in the width direction does not change, if the circumference (C) of the tissue laminate 21 in the width direction is less than 250 mm, the sides of the individual packaging film 20 will swell significantly when clamped by the guides of the device for insertion into the exterior film, making it less easy to insert into the exterior film. If the circumference (C) of the tissue laminate 21 in the width direction exceeds 340 mm, the individual packaging body 10 will be too tight, causing the tissue paper to fold or wrinkle, resulting in poor cosmetic appearance. In addition, the tissue laminate 21 will be less easy to wrap in the individual packaging film 20. The widthwise circumference (C) of the tissue laminate 21 can be measured as follows. First, the individual packaging film 20 of the individual paper product package 10 is cut, and the tissue laminate 21 is gently removed. A 30 cm ruler (Silver straight scale JIS Class 1, stainless steel, 64 g, manufactured by Shinwa Sokutei Co., Ltd.) is placed on the top surface of the tissue laminate 21 along the widthwise direction of the tissue laminate 21, and the above-mentioned dimension in the widthwise direction of the tissue laminate 21 and the height of the tissue laminate 21 are measured, and the circumference (C) is calculated as follows. Circumference (C) of the tissue stack 21 in the width direction = Dimension of the tissue stack 21 in the width direction × 2 + Height of the tissue stack 21 × 2

[0056] The ratio (D / C×100(%)) of the film circumference (D) of the individual packaging film 20 in the width direction of the individual paper product package 10 to the width direction circumference (C) of the tissue laminate 21 is 88% or more and 116% or less. If the ratio is less than 88%, the individual packaging 10 is too tight, causing the tissue paper to fold or wrinkle, resulting in poor cosmetic appearance. Also, the tissue laminate 21 is less easily packaged in the individual packaging film 20. If the ratio exceeds 116%, the sides of the individual packaging film 20 swell significantly when it is clamped by the guides of the device for insertion into the exterior film, resulting in poor insertion into the exterior film. The ratio (D / C×100(%)) of the film circumference (D) of the individual packaging film 20 in the width direction of the individual paper product package 10 to the width direction circumference (C) of the tissue laminate 21 is preferably 92% or more in lower limit, more preferably 102% or more in upper limit, and more preferably 113% or less in upper limit, more preferably 109% or less in upper limit.

[0057] The lower limit of the weight of the tissue laminate 21 is preferably 105 g or more, more preferably 110 g or more, and even more preferably 113 g or more, and the upper limit is preferably 180 g or less, more preferably 175 g or less, and even more preferably 172 g or less. If the weight of the tissue laminate 21 is less than 105g and the basis weight is the same, the longitudinal dimension (A) and height of the tissue laminate 21 will decrease, reducing the tightness of the individual package 10, causing the tissue laminate 21 to move inside the individual packaging film 20 and causing the tissue paper to fold or wrinkle, resulting in poor cosmetic appearance. If the weight of the tissue laminate 21 exceeds 180g, the force required to grip the tissue laminate 21 will increase, making it more likely to wrinkle, resulting in poor cosmetic appearance.

[0058] Furthermore, the density of the tissue laminate 21 is 0.14 g / cm 3 More than 0.24g / cm 3 The density is preferably 0.14 g / cm 3If the density is less than 0.24 g / cm, the longitudinal dimension (A) and height of the tissue laminate 21 will decrease, resulting in a decrease in the tightness of the individual package 10. This will cause the tissue laminate 21 to move inside the individual packaging film 20, causing the tissue paper to fold or wrinkle, resulting in poor cosmetic appearance. 3 If it exceeds this value, the force required to grip the tissue stack 21 will be large, making it more likely to wrinkle, resulting in poor cosmetic appearance. The density of the tissue laminate 21 has a lower limit of 0.16 g / cm 3 More preferably, it is 0.18 g / cm or more. 3 The upper limit is more preferably 0.23 g / cm. 3 More preferably, it is 0.22 g / cm or less. 3 It is even more preferable that:

[0059] The weight and density of the tissue laminate 21 are measured as follows: First, the tissue laminate 21 is taken from the individual paper product packaging 10, and the weight of the tissue laminate 21 is measured on an electronic balance after conditioning at 23°C and 50% humidity. After that, the size (width dimension, length dimension, height) of the tissue laminate 21 measured by each of the above methods is measured with a ruler, and the density is calculated according to the following formula. Density of tissue laminate 21 (g / cm 3 )=Weight of tissue stack 21 (g) / (Width dimension of tissue stack 21 (cm)×Longitudinal dimension of tissue stack 21 (cm)×Height of tissue stack 21 (cm))

[0060] The number of sets of two-ply tissue (paper) included in the tissue laminate 21 is preferably 180 sets or more and 250 sets or less. If the number of sets is less than 180 sets, the tightness of the individually wrapped paper products 10 is too low and the tissue laminate 21 moves inside the individual wrapping film 20, causing the tissue paper to fold and wrinkle, resulting in poor cosmetic appearance. If the number of sets exceeds 250 sets, the tightness of the individually wrapped paper products 10 is too high and the tissue paper to fold and wrinkle, resulting in poor cosmetic appearance. The lower limit of the number of sets in the tissue paper is more preferably 190 sets or more, and even more preferably 200 sets or more. The upper limit is more preferably 230 sets or less, and even more preferably 210 sets or less.

[0061] (Physical properties of tissue paper) The minimum basis weight of tissue paper per ply is 10.0 g / m 2 It is preferable that the content is 10.3 g / m or more. 2 More preferably, it is 10.4 g / m or more. 2 The upper limit is more preferably 12.4 g / m or more. 2 Preferably, it is 11.7 g / m or less. 2 More preferably, it is 11.1 g / m or less. 2 It is even more preferable that: The basis weight of one ply of tissue paper is 10.0 g / m 2 If the thickness is less than 12.4 g / m, the height of the tissue laminate 21 will be low, which will reduce the tightness of the individual package 10, causing the tissue laminate 21 to move inside the individual packaging film 20 and causing the tissue paper to fold or wrinkle, resulting in poor cosmetic appearance. 2 If it exceeds this value, the weight of the tissue stack 21 will be large, and the force required to grip the tissue stack 21 will be large, so that the tissue stack 21 will be prone to wrinkles, resulting in poor cosmetic appearance.

[0062] Furthermore, the lower limit of the thickness of the tissue paper is preferably 0.30 mm / 10 sheets or more, more preferably 0.40 mm / 10 sheets or more, and even more preferably 0.50 mm / 10 sheets or more, and the upper limit is preferably 0.90 mm / 10 sheets or less, more preferably 0.80 mm / 10 sheets or less, and even more preferably 0.70 mm / 10 sheets or less. When the film circumference (D) of the individual packaging film 20 in the width direction does not change, if the paper thickness of the tissue paper is less than 0.30 mm / 10 sheets, the height of the tissue laminate 21 is low, and as a result, the ratio (D / C×100(%)) of the film circumference (D) of the individual packaging film 20 in the width direction of the paper product individual package 10 to the width direction circumference (C) of the tissue laminate 21 is high, and the ease of insertion into the exterior film is poor. If the paper thickness of the tissue paper exceeds 0.90 mm / 10 sheets, the height of the tissue laminate 21 is high, and as a result, the ratio (D / C×100(%)) of the film circumference (D) of the individual packaging film 20 in the width direction of the paper product individual package 10 to the width direction circumference (C) of the tissue laminate 21 is low, and the cosmetic appearance is poor. In addition, the ease of wrapping the tissue laminate 21 in the individual packaging film 20 is also poor.

[0063] The specific volume of tissue paper has a lower limit of 3.0 cm 3 / g or more is preferable, and 4.2 cm 3 / g or more is more preferable, and 4.8 cm 3 The upper limit is preferably 7.2 cm / g or more. 3 / g or less, and 7.0 cm 3 / g or less is more preferable, and 6.3 cm 3 It is more preferable that the molecular weight is not more than 1 / g. If the perimeter of the individual packaging film 20 in the width direction does not change, the specific volume of the tissue paper is 3.0 cm 3 If the specific volume of the tissue paper is less than 7.2 cm3 / g, the height of the tissue laminate 21 will be low and the tissue laminate 21 will move inside the individual wrapping film 20 due to the lack of tightness, causing the tissue paper to fold or wrinkle, resulting in poor cosmetic appearance. 3 If it exceeds 1 / g, the height of the tissue laminate 21 will be too high and the individual packaging 10 will be too tight, causing the tissue paper to fold or wrinkle, resulting in poor cosmetic appearance. By keeping the numerical values ​​within the above range, it is possible to obtain a tissue laminate 21 and a paper product multi-package 1 that are easy to wrap with the individual packaging film 20 and have excellent cosmetic appearance.

[0064] (Manufacturing method for multi-packaging paper products) The method for manufacturing the paper product multi-package 1 according to one embodiment of the present invention can incorporate any manufacturing process used for ordinary tissue paper packages or tissue paper packaging, without any particular restrictions. For example, the paper product multi-package 1 can be manufactured through the steps of (1) tissue paper making and ply lamination, (2) manufacturing the tissue laminate 21 by laminating the tissue papers, (3) packaging and heat sealing with the individual packaging film 20, (4) inserting the individual packaging body 10 into the gusset packaging bag 30 formed with an exterior film, and (5) heat sealing the bottom surface 32 of the gusset packaging bag 30, but steps other than the above steps may also be incorporated in between. In addition, when manufacturing the multi-package paper product 1, the direction in which the individual paper product packages 10 are inserted into the gusset packaging bag 30 is preferably the vertical direction (vertical insertion) as described above. If the individual paper product packages 10 are inserted horizontally (horizontal insertion), it becomes more difficult to grasp the multiple individual paper product packages 10 than in the vertical direction, which results in poor productivity and ease of insertion into the exterior film.

[0068] (Productivity) For the manufactured products (multi-package paper products and individual package paper products), 100 packs of the products were checked, and the productivity was evaluated based on the number of products that were judged to be unshippable. The evaluation criteria are as follows: 5: The number of products that are deemed unshippable after production due to poor packaging or deterioration of cosmetic appearance is between 0 and 3 packs 4: After production, the number of products that are deemed unshippable due to poor packaging or deterioration of aesthetics is between 3 and 8 packs 3: The number of products that are deemed unshippable after production due to poor packaging or deterioration of cosmetic appearance is between 8 packs and 13 packs 2: The number of products that are deemed unshippable after production due to poor packaging or deterioration of cosmetic appearance is between 13 and 18 packs 1: After production, the number of products that are deemed unshippable due to poor packaging or deterioration of cosmetic appearance is 18 or more packs.

[0069] (Easy packaging of tissue laminate) The ease of packaging of the tissue laminate was evaluated based on the number of times the machine stopped due to packaging defects, etc., when producing 100 packs of the prepared paper product multi-packages and individual paper product packages. The evaluation criteria were as follows: 5: The number of times the machine stopped due to packaging defects during operation was 0 4: During operation, the machine stopped once due to poor packaging, etc. 3: During operation, the machine stopped twice due to packaging defects, etc. 2: During operation, the machine stopped three times due to poor packaging, etc. 1: The machine stopped due to packaging defects or other reasons four or more times during operation.

[0070] (Ease of insertion into exterior film) The ease of inserting the individual paper product packages into the exterior film was evaluated for the prepared multi-package paper products and individual paper product packages by the number of times the machine stopped due to packaging defects, etc., when producing 100 packs of the products. The evaluation criteria were as follows: 5: The number of times the machine stopped due to packaging defects during operation was 0 4: During operation, the machine stopped once due to poor packaging, etc. 3: During operation, the machine stopped twice due to poor packaging, etc. 2: During operation, the machine stopped three times due to poor packaging, etc. 1: The machine stopped due to packaging defects or other reasons four or more times during operation.

[0071] (cosmetic) The cosmetic properties of the exterior packaging, packaging and tissue of the prepared paper product multi-packages and individual paper product packages were evaluated by 30 monitors. The evaluation criteria were as follows: 5: More than 28 monitors judged the exterior, packaging, and tissue to be excellent in aesthetics. 4: The number of monitors who judged the exterior, packaging, and tissue to be excellent in aesthetics was 25 to 27. 3: The number of monitors who judged the exterior, packaging, and tissue to be excellent in aesthetics was 22 to 24. 2: The number of monitors who judged the exterior, packaging, and tissue to be excellent in aesthetics was 19 to 21 people. 1: Fewer than 18 monitors judged the exterior, packaging, and tissue to be excellent in aesthetics

[0072] The above evaluations and the parameters of each of the examples and comparative examples are shown in Tables 1 to 3 below.

[0073] [Table 1]

[0074] [Table 2]

[0075] [Table 3]

[0076] As is clear from the results shown in Tables 1 to 3, all of the packages of Examples 1 to 19 were excellent in ease of packaging the tissue laminate and ease of inserting the individually wrapped paper product into the exterior film, and were also excellent in productivity and cosmetic appearance. In contrast, all of Comparative Examples 1 to 7 were inferior in any of the productivity of the multi-package, ease of packaging the tissue laminate, ease of inserting the individually wrapped paper product into the exterior film, and cosmetic appearance. From the above, according to this embodiment, it was confirmed that the present invention can provide a paper product multi-packaging body that is easy to package a tissue laminate and easy to insert an individual paper product package into an outer film, and that has excellent productivity and aesthetic appeal.
