Description

Technical Field

[0001] The present invention relates to a pressure roll for producing a base web for a delivery label and a method for manufacturing a base web for a delivery label using the same.

Background Art

[0002] With the rapid growth of the mail-order business via the Internet, the number of packages for delivery flowing in and out of the country has increased rapidly. Delivery drivers are required to deliver more packages to the destination more efficiently in a shorter period of time. Therefore, in recent years, many improvements have been made to the form sheets attached to individual packages.

[0003] For example, Patent Documents 1 and 2 disclose forms in which a form sheet is adhesively attached to a base material via an adhesive layer so as to be peelable. In these forms, a "region without adhesive layer" where no adhesive layer is formed at the corner of the paper portion to be peeled off among the form sheets is provided, and it has been proposed to use this as a peeling start portion. However, in these forms, the difference in adhesive strength at the boundary between the region where the adhesive layer is provided and the region without adhesive layer is large, and the form sheet may be damaged or deformed when the form sheet is peeled off.

[0004] Patent Document 3 describes a peelable label in which a strongly adhesive portion and a non-adhesive or weakly adhesive portion are mixed between a base material layer and a resin layer. However, with such a label, an additional operation such as changing a part of the mixed state of the strongly adhesive portion and the non-adhesive or weakly adhesive portion is required in order to secure a region of the resin layer that is easy to grip when the delivery driver peels it off.

Embodiments for Carrying Out the Invention

[0018] The present invention will be described with reference to the accompanying drawings. In all the following drawings, components with the same reference numerals are the same as those shown in other drawings.

[0019] (Pressing roll) As shown in FIG. 1, the pressing roll 100 of the present invention includes a roll body 102.

[0020] The roll body 102 is arranged so as to be rotatable around a shaft 104 as shown in FIG. 1. The roll body 102 is preferably composed of a plurality of layered structures from around the shaft 104 toward the outer periphery, and more preferably includes a base portion 106 and a coating portion 108.

[0021] The base portion 106 is arranged along the shaft 104 and is the portion located closest to the axis of the roll body 102 in the direction of the shaft 104. The base portion 106 is made of, for example, a high-rigidity material. Examples of materials that can form the base portion 106 include rubbers such as natural rubber, isoprene rubber, butadiene rubber, styrene-butadiene rubber, acrylonitrile-butadiene rubber, butyl rubber, chloroprene rubber, chlorosulfonated polyethylene rubber, epichlorohydrin rubber, fluororubber, ethylene-propylene rubber, acrylic rubber, silicone rubber, urethane rubber; metals such as steel, stainless steel, aluminum alloy, Hastelloy; resins such as polyacetal resin; fibers or fiber-reinforced composite materials such as carbon fiber, fiber-reinforced plastic (FRP); and combinations thereof. For example, when stainless steel is used as the material for the roll body 102, surface treatment such as chrome plating may be applied to the surface to enhance durability and / or corrosion resistance.

[0022] The covering portion 108 is disposed to cover the outside of the base portion 106 and constitutes the outermost circumference of the roll body 102. The covering portion 108 has a roll surface 114 composed of an easily peelable portion forming portion 110 and a strongly adhesive portion forming portion 112. Here, the easily peelable portion forming portion 110 is a portion that can form the easily peelable portions of the original web for the delivery label and the delivery label when producing the original web for the delivery label and the delivery label, which will be described later, in the pressure roll 100. The strongly adhesive portion forming portion 112 is a portion that can form the strongly adhesive portions of the original web for the delivery label and the delivery label.

[0023] In FIG. 1, the easily peelable portion forming portion 110 is provided along a direction parallel to the circumference around the shaft 104. The number of the easily peelable portion forming portions 110 provided on the roll surface 114 is not necessarily limited. However, for example, considering that it is desired to produce a plurality of delivery labels from the original web for the delivery label obtained using such a pressure roll, it is preferable that at least two easily peelable portion forming portions 110 are provided on the roll surface 114. When a plurality of easily peelable portion forming portions 110 are provided on the roll surface 114, the interval between one easily peelable portion forming portion 110 and the adjacent easily peelable portion forming portion 110 is preferably substantially equal because a large number of delivery labels of the same size can be produced.

[0024] Furthermore, in the pressure roll 100, one strongly adhesive portion forming portion 112 is disposed between one easily peelable portion forming portion 110 and the adjacent easily peelable portion forming portion 110. Therefore, in FIG. 1, the strongly adhesive portion forming portion 112 is also provided around the shaft 104. The number of the strongly adhesive portion forming portions 112 constituting the roll surface 114 is not necessarily limited. However, for example, considering that it is desired to produce a plurality of delivery labels from the original web for the delivery label obtained using such a pressure roll, it is preferable that at least two strongly adhesive portion forming portions 112 are provided on the roll surface 114.

[0025] FIG. 2 is a cross-sectional view of the pressure roll 100 shown in FIG. 1.

[0026] As shown in Fig. 2(a), the base 106 that constitutes the roll body 102 has its inner surface in contact with the shaft 104, and the covering portion 108 is arranged to cover the outer surface of the base 106. Here, in Fig. 2(a), it is described that the inner surface of the covering portion 108 is in direct contact with the outer surface of the base 106, but the present invention is not limited to such a configuration only. For example, one or more intermediate layers (not shown) may be provided between the outer surface of the base 106 and the inner surface of the covering portion 108. The intermediate layer may be, for example, an adhesive layer containing an adhesive known in the relevant technical field, a buffer layer for absorbing and alleviating external pressure and reducing stress on the base 106 and the shaft 104, or a combination thereof.

[0027] In Fig. 2(a), the covering portion 108 is provided with a plurality of grooves 116 provided at a predetermined interval within the strongly adhered portion forming portion 112, and the easily peelable portion forming portion 110 is arranged in the grooves 116. In Fig. 2(a), the groove 116 has a trapezoidal cross-sectional shape, but is not particularly limited. As long as a part of the easily peelable portion forming portion 110 is exposed to the outside and together with a part of the strongly adhered portion forming portion 112 constitutes the roll surface 114, it may have a cross-sectional shape of any geometric shape such as a rectangle, a triangle, a semi-circle, a semi-ellipse, or the like.

[0028] In the cross-section taken along the A-A direction in Fig. 2(a), the base 106, the strongly adhered portion forming portion 112, and the easily peelable portion forming portion 110 are laminated in this order around the shaft 104 (Fig. 2(b)). On the other hand, in the cross-section taken along the B-B direction in Fig. 2(a), the base 106 and the strongly adhered portion forming portion 112 are laminated in this order around the shaft 1204 (Fig. 2(c)). Since the pressure roll 100 has such a configuration, the roll surface 114 constitutes a portion (surface) that can contact the easily peelable portion forming portion 110 and a portion (surface) that can contact the strongly adhered portion forming portion 112 in the length direction of the shaft 106.

[0029] The size of the pressing roll 100 is not particularly limited because it is set depending on the size of the base material for the delivery label desired. The length of the pressing roll 100 in the direction of the shaft 104 is, for example, 800 mm to 2200 mm. The diameter of the roll body 102 is also not particularly limited, but is, for example, 100 mm to 400 mm. The overall thickness of the covering portion 108 (that is, the thickness of the strong adhesion portion forming portion 112) and the width and depth of the groove 116 (that is, the width and thickness of the easily peelable portion forming portion 110) are not particularly limited because they vary depending on the materials used for the easily peelable portion forming portion 110 and the strong adhesion portion forming portion 112, and appropriate lengths can be appropriately selected by those skilled in the art.

[0030] The material constituting the covering portion 108 is, for example, uncrosslinked or crosslinked rubber. Examples of such rubber include low hardness rubber (rubber having a surface hardness of 1 to 20 according to the durometer A test (hereinafter sometimes simply referred to as the "durometer A test") defined in JIS K6253); general hardness rubber (rubber having a surface hardness of 30 to 70 according to the durometer A test); and high hardness rubber (rubber having a surface hardness of 80 to 90 according to the durometer A test).

[0031] More specific examples of the material constituting the covering portion 108 include natural rubber, isoprene rubber, butadiene rubber, styrene-butadiene rubber, acrylonitrile-butadiene rubber, butyl rubber, chloroprene rubber, chlorosulfonated polyethylene rubber, epichlorohydrin rubber, fluororubber, ethylene-propylene rubber, acrylic rubber, silicone rubber, urethane rubber, and combinations thereof. Chloroprene rubber and chlorosulfonated polyethylene rubber are preferred, and chlorosulfonated polyethylene rubber is more preferred because of their excellent abrasion resistance, ozone resistance, and chemical resistance.

[0032] The material constituting the covering portion 108 can vary their hardness (for example, surface hardness) depending on the type of the rubber, the amount of the vulcanization accelerator added during the processing of the rubber, the temperature applied during vulcanization (vulcanization temperature), and combinations thereof.

[0033] Examples of vulcanization accelerators that can be used include di-2-benzothiazolyl sulfide and dipentamethylene thiuram tetrasulfide, and combinations thereof. In addition to the vulcanization accelerator, vulcanization aids known to those skilled in the art may be used together. The contents of the vulcanization accelerator and vulcanization aid that can be contained in the constituent material of the coating portion 108 are not particularly limited, and any amount can be selected by those skilled in the art.

[0034] The vulcanization temperature that can be adopted is preferably 130°C to 180°C, more preferably 140°C to 170°C. If the vulcanization temperature is lower than 130°C, even in the presence of the above vulcanization accelerator, the crosslinking of the rubber does not proceed efficiently, and a base portion or a coating portion having sufficient surface roughness may not be obtained. If the vulcanization temperature exceeds 180°C, the coating portion may become too hard and cracks may occur.

[0035] In addition to the rubber, vulcanization accelerator, and vulcanization aid as described above, the constituent material of the coating portion 108 may contain other additives as long as the heat resistance, abrasion resistance, and / or surface hardness of the coating portion 108 are not impaired.

[0036] Examples of such other additives include, but are not necessarily limited to, ultraviolet absorbers (e.g., benzophenone-based ultraviolet absorbers and / or benzotriazole-based ultraviolet absorbers); antistatic agents (e.g., anionic surfactants, cationic surfactants, nonionic surfactants, and / or amphoteric surfactants); clarifying agents (e.g., metal carboxylates, sorbitols, and / or metal phosphate esters); lubricants (e.g., hydrocarbon-based lubricants, fatty acid-based lubricants, higher alcohol-based lubricants, fatty acid amide-based lubricants, metal soap-based lubricants, and / or ester-based lubricants); flame retardants (e.g., organic flame retardants and / or inorganic flame retardants); and plasticizers (e.g., epoxidized vegetable oils, phthalate esters, and / or polyester-based plasticizers); and combinations thereof. The content of the above other additives that can be contained in the material constituting the coating portion 108 is not particularly limited, and any amount can be selected by those skilled in the art.

[0037] In addition, in the present invention, it is preferable that the easily peelable portion forming portion 110 and the strongly adhering portion forming portion 112 in the covering portion 108 each have an independent surface hardness, and it is more preferable that there is a difference in surface hardness within a predetermined range between the two. Since the surface hardnesses of the easily peelable portion forming portion 110 and the strongly adhering portion forming portion 112 have such a relationship, it is possible to provide an easily peelable portion and a strongly adhering portion having different peel strengths within the same base fabric for a delivery label produced using the pressure roll 100 of the present invention.

[0038] Here, the surface hardness (I hk ) of the easily peelable portion forming portion 110 by the durometer A test is preferably 5 to 80, more preferably 10 to 75. When the surface hardness (I hk ) of the easily peelable portion forming portion 110 exceeds 80, this portion becomes difficult to grasp, and it may become difficult to start peeling from this portion.

[0039] On the other hand, the surface hardness (K hk ) of the strongly adhering portion forming portion 112 by the durometer A test is preferably 70 to 100, more preferably 70 to 90. When the surface hardness (K hk ) of the strongly adhering portion forming portion 112 is less than 70, the difference in properties between the easily peelable portion and the strongly adhering portion of the obtained delivery label may become small. When the surface hardness (K hk ) of the strongly adhering portion forming portion 112 exceeds 100, the peeling of the strongly adhering portion of the obtained delivery label becomes difficult, and the label may be torn during peeling.

[0040] Also, in the present invention, it is preferable that the surface hardness (I hk ) of the easily peelable portion forming portion 110 is designed to be smaller than the surface hardness (K hk ) of the strongly adhering portion forming portion 112 (I hk <K hk ). With such a surface hardness of I hk <K hkBy satisfying the relationship, the easily peelable portion of the delivery label to be produced later is formed through the easily peelable portion forming portion 110 of the pressure roll 100, and the strongly adhesive portion of the label can be formed through the strongly adhesive portion forming portion 112 of the pressure roll 100.

[0041] Furthermore, in the present invention, the surface hardness (K hk ) of the strongly adhesive portion forming portion 112 and the surface hardness (I hk ) of the easily peelable portion forming portion 110, the difference (K hk -I hk ) is preferably 10 to 40, more preferably 15 to 35. When the difference (K hk -I hk ) is less than 10, the difference in peel strength between the easily peelable portion and the strongly adhesive portion in the delivery label to be produced later becomes small, and when peeling the base material from the delivery label, breakage or deformation of the peeled base material may occur. When the difference (K hk -I hk ) exceeds 40, for example, when the obtained delivery label is attached to a delivered product and delivered, if an attempt is made to peel the base material through the easily peelable portion, the base material may be subjected to large strain, resulting in tearing or undesired curling.

[0042] Here, in the pressure roll 100 shown in FIG. 1, the easily peelable portion forming portion 110 and the strongly adhesive portion forming portion 112 that constitute the covering portion 108 of the roll body 102 each form a uniform surface, and it is designed so that substantially no step is generated between the surface constituting the easily peelable portion forming portion 110 and the surface constituting the strongly adhesive portion forming portion 112 (FIG. 3(a)).

[0043] On the other hand, in the present invention, as shown in FIG. 3(b), the easily peelable portion forming portion 110' may have fine irregularities.

[0044] The peelable portion forming section 110' shown in Fig. 3(b) is similar to the peelable portion forming section 110 shown in Figs. 1 and 3(a) in that it is provided between two strong adhesion portion forming sections 112. On the other hand, the peelable portion forming section 110' has an uneven outer surface formed by a combination of convex portions 132 divided into a plurality of rectangles and concave portions 134 divided into a plurality of rectangles, rather than having a uniform outer surface, which is different from the peelable portion forming section 110 shown in Fig. 3(a).

[0045] Here, in Fig. 3(b), for example, the convex portion 132 constituting the peelable portion forming section 110' has no step with the forming surface of the strong adhesion portion forming section 112, and the two can form a substantially uniform surface.

[0046] On the other hand, the outer surface of the concave portion 134 included in the peelable portion forming section 110' is recessed by a length corresponding to the step d lower than the surface constituting the strong adhesion portion forming section 112. When a flat material (for example, the constituent material of the base fabric for the delivery level) is arranged on the surface constituting the strong adhesion portion forming section 112, it is designed to generate a gap corresponding to the step d. As a result, in the concave portion 134 of the peelable portion forming section 110', the pressing force from the pressing roll is not transmitted to the flat material due to the gap. As a result, the pressing force received from the entire peelable portion forming section 110' can be reduced by an amount corresponding to the outer surface of the concave portion 134 with respect to the outer surface of the entire peelable portion forming section 110'. Such a step d is preferably 0.5 mm to 3 mm, and more preferably 1 mm to 2 mm.

[0047] In addition, in the peelable portion forming section 110' shown in Fig. 3(b), by changing the combination of the convex portion 132 and the concave portion 134, the average value of the surface hardness of the peelable portion forming section 110' per unit area of the peelable portion forming section 110' (hereinafter referred to as the average surface hardness) can be varied.

[0048] For example, a case will be described where both the convex portion 132 and the concave portion 134 in the easily detachable portion forming section 110’ have a rectangular (square) shape having the same sectional area when viewed from above.

[0049] Assuming that the average surface hardness per unit area of the easily detachable portion forming section 110 as shown in FIG. 1 (the average surface hardness of the rectangular region R composed of the four convex portions 132 as shown in FIG. 4(a)) is 100%, when the convex portion 132 and the concave portion 134 are arranged in a checkered pattern as shown in FIG. 4(b), the average surface hardness of the rectangular region R including two convex portions 132 and two concave stripes 134 is 50%. Alternatively, as shown in FIG. 4(c), when one rectangular region R is composed of three convex portions 132 and one concave portion 134, the average surface hardness of the rectangular region R is 75% with respect to the average surface hardness (100%) of the rectangular region R. Alternatively, as shown in FIGS. 4(d) and (e), when one rectangular region R or R is composed of two convex portions 132 and two concave portions 134 arranged side by side, the average surface hardness of the rectangular regions R and R is both 50% with respect to the average surface hardness (100%) of the rectangular region R. Alternatively, as shown in FIG. 4(f), when one rectangular region R is composed of one convex portion 132 and three concave portions 134, the average surface hardness of the rectangular region R is 25% with respect to the average surface hardness (100%) of the rectangular region R. a b c c a d e d e a f f a

[0050] In the above, the case where both the convex portion 132 and the concave portion 134 constituting the easily detachable portion forming section 110’ are rectangular and have the same sectional area has been described, but the present invention is not limited thereto. The convex portion 132 and the concave portion 134 that can constitute the easily detachable portion forming section 110’ may each independently have an arbitrary shape and size.

[0051] Figure 5 is a perspective view of the pressure roll of the present invention showing another example of the roll.

[0052] The pressure roll 200 shown in Figure 5 includes a roll body 202, and the roll body 202 is also arranged to be rotatable around the shaft 104. The roll body 202 preferably includes a base portion 106 and a coating portion 208 as a plurality of layered structures from around the shaft 104 to the outer periphery.

[0053] The coating portion 208 is arranged to cover the outside of the base portion 106 and constitutes the outermost periphery of the roll body 202. The coating portion 208 has a roll surface 214 composed of an easily peelable portion forming portion 210 and a strongly adhering portion forming portion 212.

[0054] In Figure 5, the easily peelable portion forming portion 210 is provided along a direction parallel to the shaft 104. The number of the easily peelable portion forming portions 210 constituting the roll surface 214 is not necessarily limited. For example, considering manufacturing a plurality of delivery labels from a base material for delivery labels obtained using such a pressure roll, it is preferably provided with at least two. When a plurality of easily peelable portion forming portions 210 are provided on the roll surface 214, their intervals are preferably substantially equal along the circumferential direction of the coating portion 208 because a large number of delivery labels of the same size can be manufactured.

[0055] Furthermore, in the pressure roll 200, one strongly adhering portion forming portion 212 is arranged between one easily peelable portion forming portion 210 and the adjacent easily peelable portion forming portion 210. Therefore, in Figure 5, the strongly adhering forming portion 212 is also provided along a direction parallel to the shaft 104. The number of the strongly adhering portion forming portions 212 constituting the roll surface 214 is not necessarily limited. For example, considering manufacturing a plurality of delivery labels from a base material for delivery labels obtained using such a pressure roll, it is preferably provided with at least two.

[0056] Figure 6 is a cross-sectional view of the pressure roll 200 shown in Figure 5.

[0057] As shown in Fig. 6(a), the base 106 that constitutes the roll body 202 has its interior in contact with the shaft 104, and the covering portion 208 is arranged to cover the outer surface of the base 106. An intermediate layer (not shown) may be provided between the outer surface of the base 106 and the inner surface of the covering portion 208.

[0058] In Fig. 6(a), the covering portion 208 is provided with a peelable portion forming portion 210 that extends parallel to the axial direction of the shaft 104. On the other hand, in the cross-section taken along the A'-A' direction in Fig. 6(a), the base 106 and the strong adhesion portion forming portion 212 are arranged around the shaft 104, and a groove 216 having a trapezoidal cross-sectional shape is provided in a part of the outer surface of the strong adhesion portion forming portion 212, and the peelable portion forming portion 210 is arranged in the groove 216 (Fig. 6(b)). Although the groove 216 has a trapezoidal cross-sectional shape in Fig. 6(b), it is not particularly limited, and as long as a part of the peelable portion forming portion 210 is exposed to the outside and together with a part of the strong adhesion portion forming portion 212 constitutes the roll surface 214, it may have any cross-sectional shape such as a rectangle, a triangle, a semi-circle, a semi-ellipse, or other arbitrary geometric shapes. Since the pressure roll 200 has such a configuration, the roll surface 214 constitutes a portion (surface) that can contact the peelable portion forming portion 210 and a portion (surface) that can contact the strong adhesion portion forming portion 212 around the axis of the shaft 106.

[0059] The size of the pressure roll 200 is not particularly limited because it is set depending on the size of the desired base material for the delivery label, and it is designed to have the same size as the pressure roll 100 shown in Fig. 1. The overall thickness of the covering portion 208 and the depth of the groove 216 (that is, the thickness of the peelable portion forming portion 210) are not particularly limited, and an appropriate length can be appropriately selected by those skilled in the art.

[0060] The materials that constitute the base 106 and the covering portion 208 are the same as the materials that constitute the base 106 and the covering portion 108 shown in Fig. 1 above.

[0061] Fig. 7 is a perspective view of the roll showing still another example of the pressure roll of the present invention.

[0062] The pressure roll 300 shown in FIG. 7 includes a roll body 302, and the roll body 302 is also arranged to be rotatable around the shaft 104. The roll body 302 preferably includes a base portion 106 and a covering portion 308 as a plurality of layered structures from around the shaft 104 to the outer periphery.

[0063] The covering portion 208 is arranged to cover the outside of the base portion 106 and constitutes the outermost periphery of the roll body 302. The covering portion 308 has a roll surface 314 composed of an easily peelable portion forming portion 310 and a strongly adhesive portion forming portion 312.

[0064] In FIG. 7, the easily peelable portion forming portion 310 is configured such that a region portion 310a provided along a direction parallel to the shaft 104 and a region portion 310b provided along a direction parallel to the circumference of the shaft 104 intersect each other at, for example, a substantially right angle. The number of each of the region portions 310a and 310b on the roll surface 314 is not necessarily limited. However, for example, considering manufacturing a plurality of delivery labels from a base web for delivery labels obtained using such a pressure roll, it is preferable that at least two of each are provided independently.

[0065] Furthermore, in the pressure roll 300, one strongly adhesive portion forming portion 312 is arranged in a portion surrounded by one easily peelable portion forming portion 310 (that is, a portion surrounded by two opposing region portions 310a and two opposing region portions 310b). The number of strongly adhesive portion forming portions 312 constituting the roll surface 314 is not necessarily limited. However, for example, considering manufacturing a plurality of delivery labels from a base web for delivery labels obtained using such a pressure roll, it is preferable that at least two are provided.

[0066] As shown in FIG. 8(a), the base portion 106 constituting the roll body 302 has an inner surface in contact with the shaft 104, and the covering portion 308 is arranged to cover the outer surface of the base portion 106. An intermediate layer (not shown) may be provided between the outer surface of the base portion 106 and the inner surface of the covering portion 308.

[0067] In FIG. 8(a), in the covering portion 308, a region portion 310a of an easily peelable portion forming portion 310 extending parallel to the axial direction of the shaft 104 is arranged. On the other hand, in the cross section taken along the A''-A'' direction in FIG. 8(a), a base portion 106 and a strong adhesion portion forming portion 312 are arranged around the shaft 104, and further, a region portion 310b of the easily peelable portion forming portion 310 is arranged thereon (FIG. 8(b)). Also, in the cross section taken along the B''-B'' direction in FIG. 8(a), a base portion 106 and a strong adhesion portion forming portion 312 are arranged around the shaft 104, and a groove 316 having a trapezoidal cross-sectional shape is provided on a part of the outer surface of the strong adhesion portion forming portion 312, and the region portion 310a of the easily peelable portion forming portion 310 is arranged in the groove 316 (FIG. 8(c)). Although the groove 316 has a trapezoidal cross-sectional shape in FIG. 8(c), it is not particularly limited, and as long as a part of the easily peelable portion forming portion 310 is exposed to the outside and forms the roll surface 314 together with a part of the strong adhesion portion forming portion 312, it may have any cross-sectional shape of a rectangle, a triangle, a semi-circle, a semi-ellipse, or any other geometric shape. Since the pressure roll 300 has such a configuration, the roll surface 314 constitutes a portion (surface) that can contact the easily peelable portion forming portion 310 and a portion (surface) that can contact the strong adhesion portion forming portion 312 in both the length direction of the shaft 106 and the direction around the shaft.

[0068] The size of the pressure roll 300 is not particularly limited because it is set depending on the size of the base web for the delivery label desired, and it is designed to have the same size as the pressure roll 100 shown in FIG. 1. The overall thickness of the covering portion 308, the depth of the groove 316, etc. are not particularly limited, and an appropriate length can be appropriately selected by those skilled in the art.

[0069] The materials constituting the base portion 106 and the covering portion 308 are the same as the materials constituting the base portion 106 and the covering portion 108 shown in FIG. 1 above.

[0070] (Method for producing a base web for a delivery label) The base web for the delivery label can be produced by laminating the base material layer and the thermoplastic resin layer with the above-mentioned pressure roll. A method for producing such a base web for the delivery label will be described with reference to the drawings.

[0071] FIG. 9 is a schematic diagram showing an example of an apparatus for producing a base web for a delivery label using the pressure roll of the present invention.

[0072] As shown in FIG. 9, in the apparatus 500 for producing a base web for a delivery label, the pressure roll 100 of the present invention shown in FIG. 1 and the cooling roll 570 are arranged with a gap (air gap) k of, for example, 90 to 120 μm therebetween. A backup roll 560 is provided in contact with the pressure roll 100 behind the pressure roll 100.

[0073] In such an apparatus 500, the base material layer 510 and the thermoplastic resin layer 520 are supplied in an overlapping manner into the gap k between the pressure roll 100 and the cooling roll 570. When the overlapping of the base material layer 510 and the thermoplastic resin layer 520 passes through the gap k, they are sandwiched (pressed by the pressure roll) between the pressure roll 100 and the cooling roll 570 and formed into a first laminate 530 as shown in FIG. 10(a).

[0074] Here, the base material layer 510 that can constitute the first laminate 530 is composed of paper, synthetic resin, etc. that can be printed or written on. From the viewpoint of being usable as the printing surface of the delivery label described later, the base material layer 510 is preferably thermal paper or inkjet paper.

[0075] Thermal paper is printing paper that reacts to heat and is processed to develop a predetermined color such as black, and is easy to print and widely used. In the present invention, commercially available thermal paper can be used. Representative thermal papers include DL82AS Thermal manufactured by Oji Imaging Media Co., Ltd., and FI paper manufactured by Nippon Paper Industries Co., Ltd. Inkjet paper is surface-treated so that inkjet printing is easy, the ink develops well, the ink is easily arranged on the surface, the absorption of the ink is good, and the drying is fast. Commercially available inkjet paper can be used.

[0076] The thermoplastic resin layer 520 that can form the first laminate 530 is a layer made of a thermoplastic resin composed of at least one layer, and preferably has a thickness of 13 μm to 20 μm, more preferably 16 μm to 17 μm. Examples of the thermoplastic resin that forms the thermoplastic resin layer 520 include polyolefins (for example, polyolefin resins such as polyethylene and polypropylene), polystyrene resins, polyester resins, and polyamide resins. It is preferably a polyethylene resin film because of its high versatility and good heat sealability.

[0077] The polyethylene resin that can be used for the thermoplastic resin layer enhances the adhesion to the adhesive applied to kraft paper or the like used as a packaging material, enables the release of the thermal paper during the delivery of the delivered goods, and allows the thermal paper portion described by printing or the like on the surface to be used as a receipt. As the polyethylene resin, commercially available resins such as high-density polyethylene, medium-density polyethylene, low-density polyethylene, ultra-low-density polyethylene, and other modified polyethylenes can be used. It is preferably medium-density polyethylene, low-density polyethylene, or ultra-low-density polyethylene because it has appropriate adhesion to the above substrate and good peelability can be obtained.

[0078] Referring to FIG. 9 again, the first laminate 530 obtained by the nip pressure between the pressure roll 100 and the cooling roll 570 is superposed with a separately provided release layer 540 and supplied to the gap between the pinch rolls 580 and 590. The superposition of the first laminate 530 and the release layer 540 is performed such that the arrangement surface of the thermoplastic resin layer 520 that forms the first laminate 530 is in direct contact with the release layer 540. Further, this superposition is preferably performed in a state where the first laminate 530 has appropriate residual heat by nip pressure between the pressure roll 100 and the cooling roll 570 in order to enhance the adhesiveness between the first laminate 530 and the release layer 540.

[0079] The release layer 540 is, for example, as shown in FIG. 10(b), a second laminate formed by sequentially laminating a release agent layer 544 such as a silicone release agent and an adhesive layer 546 such as an acrylic adhesive, a rubber adhesive, or a urethane adhesive on a release paper 542.

[0080] Referring again to FIG. 9, from the first laminate 530 and the release layer 540 thus overlapped, a base web 550 for a delivery label is produced by pressing between the pinch rolls 580 and 590. That is, the base web 550 for a delivery label has the first laminate 530 disposed on the release layer 540, and has a structure in which, for example, a release agent layer 544, an adhesive layer 546, a thermoplastic resin layer 520, and a base material layer 510 are laminated in this order on the release paper 542 (FIG. 10(c)).

[0081] FIG. 11 is a schematic diagram showing the relationship between the pressure roll 100 shown in FIG. 2(a) and the arrangement of the easily peelable portion and the strongly adhesive portion in the base web 550 for a delivery label obtained using the same.

[0082] In the base web 550 for a delivery label shown in FIG. 11, it has two parallel edges 551 and 551' along the supply direction (also referred to as the machine direction or the longitudinal direction (MD); indicated by the white arrow in FIG. 11), and at least two easily peelable portions 552 are preferably provided along a direction parallel to the edges 551 and 551'. In other words, in the base web 550 for a delivery label shown in FIG. 11, one or more easily peelable portions 552 and one or more strongly adhesive portions 554 are alternately arranged side by side.

[0083] The easily peelable portion 552 is a portion pressed through the easily peelable portion forming portion 110 of the pressure roll 100 during the pressing between the pressure roll 100 and the cooling roll 570 shown in FIG. 9 above. In contrast, the strongly adhesive portion 554 is a portion pressed through the strongly adhesive portion forming portion 112 of the pressure roll 100 during the pressing between the pressure roll 100 and the cooling roll 570 shown in FIG. 9 above.

[0084] In the base web 550 for a delivery label, the adhesive strength between the base material layer and the thermoplastic resin layer is different between the easily peelable portion 552 and the strongly adhesive portion 554, and preferably, the adhesive strength of the strongly adhesive portion 554 is designed to be higher than the adhesive strength of the easily peelable portion 552. Here, the comparison between the adhesive strength of the strongly adhesive portion 554 and the adhesive strength of the easily peelable portion 552 is made as follows: taking a sample long in the machine direction, a sample of the strongly adhesive portion obtained from the base web for a delivery label is 150 mm × 50 mm, and a sample of the easily peelable portion is 150 mm × 10 mm. The adhesive strength of these samples is measured in accordance with JIS K6854-1977, and further, the adhesive strength of the obtained sample of the easily peelable portion is multiplied by 5.

[0085] In the base web 550 for a delivery label, the difference between the adhesive strength of the strongly adhesive portion 554 and the adhesive strength of the easily peelable portion 552 is preferably 180 mN / 50 mm to 950 mN / 500 mm, more preferably 190 mN / 50 mm to 750 mN / 50 mm. When the difference in the adhesive strength satisfies such a range, the base web 550 for a delivery label of the present invention can easily peel the base material layer from the thermoplastic resin layer with less force in the easily peelable portion 552 as compared with the strongly adhesive portion 554.

[0086] As described above, in FIG. 11, the relationship between the arrangement of the easily peelable portion and the strongly adhesive portion of the base web for a delivery label obtained by using the pressure roll 100 shown in FIG. 2(a) (that is, the pressure roll 100 shown in FIG. 1) was described, but the relationship of the arrangement is not particularly limited thereto. For example, when the pressure roll 200 shown in FIG. 6(a) (that is, the pressure roll 200 shown in FIG. 5) is used, in the obtained base web for a delivery label, an easily peelable portion is formed in a direction perpendicular to the two opposing edges (that is, the width direction of the base web for a delivery label). Alternatively, when the pressure roll 300 shown in FIG. 8(a) (that is, the pressure roll 300 shown in FIG. 7) is used, in the obtained base web for a delivery label, easily peelable portions are formed in both a direction parallel to the two opposing edges (that is, the width direction of the base web for a delivery label) and a direction perpendicular to the two opposing edges (that is, the width direction of the base web for a delivery label).

[0087] (Shipping Label) The shipping label of the present invention is produced, for example, by cutting out the portion 556 enclosed by the broken line from the original sheet 550 for the shipping label shown in FIG. 11.

[0088] FIG. 12(a) is a schematic diagram showing an example of the shipping label 556 obtained from the original sheet 550 for the shipping label of FIG. 11.

[0089] The shipping label 556 has, for example, a rectangular shape and is configured to include a base material layer 510 and a thermoplastic resin layer 520. The shipping label 556 also includes a peelable portion 552 formed by a surface including at least one side of the rectangle, and a strong adhesive portion 554 formed by the other surface, and these adhesive strengths are configured to be different from each other.

[0090] In the shipping label 556, the difference between the adhesive strength of the strong adhesive portion 554 and the adhesive strength of the peelable portion 552 is the same as that of the original sheet 550 for the shipping label shown in FIG. 11. That is, the difference in the adhesive strength is preferably 180 mN / 50 mm to 950 mN / 50 mm, more preferably 190 mN / 50 mm to 750 mN / 50 mm. When the difference in the adhesive strength satisfies such a range, the shipping label 556 of the present invention can easily peel the base material layer 510 from the thermoplastic resin layer 520 with less force in the peelable portion 552 compared to the strong adhesive portion 554, as shown in FIG. 12(b) for example, and can prevent the base material layer from curling after peeling.

[0091] According to the shipping label of the present invention, printing such as a name and address is made on the base material layer. On the other hand, the release paper of the release layer is peeled off and directly attached to a cardboard box or the like storing the shipping goods. In this state, the cardboard box containing the goods is delivered by the delivery person to the customer's designated address. When the delivery person finishes delivering to the customer, the base material layer or a part thereof can be peeled off by the delivery person from the above-mentioned peelable portion as a preparation for delivery. In addition, since the peeled base material layer is prevented from curling when a plurality of sheets are bundled and taken home, it is possible to reduce the bulkiness of the bundle and the annoyance of taking it home.

Example

[0092] Hereinafter, the present invention will be described in detail with reference to examples, but the present invention is not limited to these examples.

[0093] The test methods and evaluation methods adopted in each of the examples and comparative examples are as follows.

[0094] (Surface hardness of the coated part) The surface hardness of the coated part of the produced pressure roll was measured by the durometer A test according to JIS K6253.

[0095] (Adhesion strength) Regarding the produced delivery label, as a sample long in the machine direction, samples of the strongly adhesive part obtained from the delivery label were cut out to be 150 mm × 50 mm, and samples of the easily peelable part were cut out to be 150 mm × 10 mm. Arbitrary 6 points were selected from these samples respectively, and their adhesion strengths were measured according to JIS K6854-1977. In addition, in order to compare with the results of the samples of the strongly adhesive part, the adhesion strength of the samples of the easily peelable part was calculated by multiplying the measured value by 5. Also, the average value of the measurement results of these 6 points was calculated, and this was taken as the adhesion strength.

[0096] (Stability of the lamination line) The stability of the lamination line when laminating the release layer on the first laminate (a laminate of a base material layer and a thermoplastic resin layer) obtained in the examples and comparative examples was visually evaluated. Those in which no meandering or peeling occurred during this lamination were represented by "〇", and those in which meandering or peeling occurred were represented by "×".

[0097] (Peeling workability) For the delivery labels obtained in the examples and comparative examples, the release paper on the release layer side was peeled off, and after being attached to corrugated cardboard for packaging, it was left for a whole day and night. Then, the end of the easily peelable part of the thermal paper, which is the base material layer, was grasped by hand, and the thermal paper was peeled off to evaluate the ease of peeling. Those with easily graspable ends and capable of performing a large number of peeling operations in a short time were evaluated as "〇", those with easily graspable ends but requiring time-consuming peeling operations for damage prevention and curling prevention were evaluated as "△", and those with difficult-to-grasp ends or requiring laborious peeling operations were evaluated as "×".

[0098] (Comparative Example 1: Preparation of Pressing Roll (R-1)) 100 parts by mass of chlorosulfonated polyethylene (TOSO-DSMR manufactured by Tosoh Corporation), 0.5 parts by mass of vulcanization accelerator (di-2-benzothiazolyldisulfide), 2 parts by mass of vulcanization accelerator (dipentamethylenethiuram tetrasulfide), 40 parts by mass of reinforcing material (SFR carbon black), and 27.8 parts by mass of vulcanization aid (lead oxide with a purity of 90%) were mixed, and at a vulcanization temperature of 150 °C and a vulcanization pressure of 0.4 MPa, it was placed as a coating part on a rubber base previously arranged on the surface of a roll core metal, thereby obtaining a pressing roll (R-1) with an effective width of 1700 mm and a coating part thickness of 35 mm. A total of 5 such pressing rolls (R-1) were prepared.

[0099] The surface hardness of the coating part in this pressing roll (R-1) was 80.

[0100] (Comparative Example 2: Preparation of Pressing Roll (R-2)) For 4 of the pressing rolls (R-1) prepared in Comparative Example 1, 3 grooves with a rectangular cross-section shape of 15 mm in width and 10 mm in depth were provided on the entire circumference of the coating part at positions equally divided in the width direction on the surface of the coating part so as to be parallel to each other, thereby obtaining a pressing roll (R-2) with an effective width of 1700 mm and a coating part thickness of 35 mm.

[0101] The surface hardness of the coating part (the part other than the grooves) in this pressing roll (R-2) was 80.

[0102] (Example 1: Production of Press Roll (R-3)) 100 parts by mass of chlorosulfonated polyethylene (TOSO-DSMR manufactured by Tosoh Corporation), 0.5 parts by mass of a vulcanization accelerator (di-2-benzothiazolyldisulfide), 2 parts by mass of a vulcanization accelerator (dipentamethylenethiuram tetrasulfide), 35 parts by mass of a reinforcing material (SFR carbon black), and 27.8 parts by mass of a vulcanization aid (lead oxide with a purity of 90%) were mixed, heated at a vulcanization temperature of 150°C under a vulcanization pressure of 0.4 MPa, and processed into the form of a string-like rubber, which was placed in all the grooves within the coating portion of one of the rolls of the press roll (R-2) obtained in Comparative Example 2. As a result, a press roll (R-3) with an effective width of 1700 mm and a coating portion thickness of 35 mm was obtained. At that time, it was visually confirmed that there were no irregularities between the roll surface other than the grooves and the outer surface of the string-like rubber placed in the grooves, and a substantially uniform surface was formed.

[0103] The surface hardness of the portion where the string-like rubber was placed in the coating portion of this press roll (R-3) was 70, and the surface hardness of the other portions was 80.

[0104] (Example 2: Production of Press Roll (R-4)) 100 parts by mass of chlorosulfonated polyethylene (TOSO-DSMR manufactured by Tosoh Corporation), 0.5 parts by mass of a vulcanization accelerator (di-2-benzothiazolyldisulfide), 2 parts by mass of a vulcanization accelerator (dipentamethylenethiuram tetrasulfide), 30 parts by mass of a reinforcing material (SFR carbon black), and 27.8 parts by mass of a vulcanization aid (lead oxide with a purity of 90%) were mixed, vulcanized at a vulcanization temperature of 150°C under a vulcanization pressure of 0.4 MPa, and processed into the form of a string-like rubber, which was placed in all the grooves within the coating portion of one of the rolls of the press roll (R-2) obtained in Comparative Example 2 through a rubber adhesive. Then, by slightly machining it until the entire surface of the roll became smooth, a press roll (R-4) with an effective width of 1700 mm and a coating portion thickness of 35 mm was obtained.

[0105] Among the coated parts of this pressure roll (R-4), the surface hardness of the part where the string-shaped rubber was placed was 60, and the surface hardness of the other parts was 80.

[0106] (Example 3: Production of Pressure Roll (R-5)) A pressure roll (R-5) with an effective width of 1700 mm and a coated part thickness of 35 mm was obtained in the same manner as in Example 1, except that the addition amount of the reinforcing agent (SRF carbon black) was changed to 25 parts by mass.

[0107] Among the coated parts of this pressure roll (R-5), the surface hardness of the part where the string-shaped rubber was placed was 50, and the surface hardness of the other parts was 80.

[0108] (Comparative Example 3: Production of Delivery Label (C1)) Using the rubber roll (R-2) produced in Comparative Example 2, the lamination of the low-density polyethylene resin onto the heat-sensitive paper was carried out as follows.

[0109] As a pressure roll, the pressure roll (R-2) produced in Comparative Example 2 was attached to a T-die extruder for lamination with a diameter of 115 mm and a die width of 1600 mm. The low-density polyethylene resin (SumikaSen (registered trademark) CE4009 (L405) manufactured by Sumitomo Chemical Co., Ltd.) was laminated onto the pressure-sensitive paper (roll-shaped heat-sensitive paper DL82AS Thermal: basis weight 82 g, width 910 mm) at a resin temperature of 235 °C, a rubber roll pressure of 1.5 Kg / m 2 (original pressure) and a line speed of 100 m / min to obtain a first laminate.

[0110] On the other hand, an appropriate amount of a silicone-based release agent was applied to a roll-shaped base paper for release paper with a width of 900 mm, dried in a dryer to form a release agent layer, and then an appropriate amount of an acrylic-based adhesive was applied onto the release agent layer and dried in a dryer to form a release layer.

[0111] Thereafter, while there is still residual heat in the first laminate obtained above, the first laminate and the release layer are arranged such that the low-density polyethylene resin layer of the first laminate and the application surface of the acrylic adhesive of the release layer are in contact with each other, and pinched with pinch rollers to obtain a base web for a delivery label.

[0112] Next, a delivery label (C1) was obtained by cutting out a size of 220 mm × 150 mm from this base web for a delivery label. In addition, it was confirmed that a peelable portion formed by passing through the groove (10 mm) of the pressure roll (R-2) was arranged on the short side (150 mm) side of this delivery label (C1) with a width of about 10 mm.

[0113] Table 1 shows the evaluation results for this delivery label (C1).

[0114] (Example 4: Production of Delivery Label (E1)) Using the rubber roll (R-3) produced in Example 1, lamination of the low-density polyethylene resin onto the thermal paper was carried out as follows.

[0115] As a pressure roll, the pressure roll (R-3) produced in Example 1 was attached to a T-die extruder for lamination with a diameter of 115 mm and a die width of 1600 mm. Low-density polyethylene resin (Sumika Sen (registered trademark) CE4009 (L405) manufactured by Sumitomo Chemical Co., Ltd.) was laminated onto thermal pressure-sensitive paper (roll-shaped thermal paper DL82AS manufactured by Oji Imaging Media Co., Ltd.: basis weight 82 g, width 910 mm) at a resin temperature of 235°C, a rubber roll pressure of 1.5 Kg / m 2 (original pressure) and a line speed of 100 m / min to obtain a first laminate.

[0116] On the other hand, an appropriate amount of a silicone-based release agent was applied to a roll-shaped base paper for release paper with a width of 900 mm, dried in a dryer to form a release agent layer, and then an appropriate amount of an acrylic adhesive was applied onto the release agent layer and dried in a dryer to form a release layer.

[0117] Thereafter, while there is still residual heat in the first laminate obtained above, the first laminate and the release layer are arranged such that the low-density polyethylene resin layer of the first laminate and the application surface of the acrylic adhesive of the release layer are in contact with each other, and pinched with pinch rollers to obtain a base web for a delivery label.

[0118] Next, a delivery label (E1) was obtained by cutting out from this base web for a delivery label in a size of 220 mm × 150 mm. It was confirmed that on the short side (150 mm) of this delivery label (E1), there was arranged a peelable portion formed by a string-like rubber (10 mm) arranged in the groove of the above-mentioned pressure roll (R-3) passing through with a width of about 10 mm.

[0119] Table 1 shows the evaluation results for each of this delivery label (E1).

[0120] (Example 5: Production of Delivery Label (E2)) A base web for a delivery label was obtained in the same manner as in Example 4, except that a first laminate obtained by laminating low-density polyethylene on thermal paper using the rubber roll (R-4) produced in Example 2 was used.

[0121] Next, a delivery label (E2) was obtained by cutting out from this base web for a delivery label in a size of 220 mm × 150 mm. It was confirmed that on the short side (150 mm) of this delivery label (E2), there was arranged a peelable portion formed by a string-like rubber (10 mm) arranged in the groove of the above-mentioned pressure roll (R-4) passing through with a width of about 10 mm. Table 1 shows the evaluation results for each of the delivery label (E2).

[0122] (Example 6: Production of Delivery Label (E3)) A base web for a delivery label was obtained in the same manner as in Example 4, except that a first laminate obtained by laminating low-density polyethylene on thermal paper using the rubber roll (R-5) produced in Example 3 was used.

[0123] Next, by cutting out from this original sheet for delivery labels in a size of 220 mm × 150 mm, a delivery label (E3) was obtained. In addition, it was confirmed that on the short side (150 mm) of this delivery label (E3), there was arranged a peelable portion formed by a string-shaped rubber (10 mm) arranged in the groove of the above-mentioned pressure roll (R-5) passing through with a width of about 10 mm. Table 1 shows the evaluation results for the delivery label (E3).

[0124] (Comparative Example 4: Production of Delivery Label (C2)) An original sheet for delivery labels was obtained in the same manner as in Example 4, except that a first laminate obtained by laminating low-density polyethylene on thermal paper using the rubber roll (R-1) produced in Comparative Example 1 was used.

[0125] Next, by cutting out from this original sheet for delivery labels in a size of 220 mm × 150 mm, a delivery label (C2) was obtained. In addition, it was confirmed that no peelable portion was arranged on either the short side (150 mm) or the long side (220 mm) of this delivery label (C2), and that the thermal paper and the low-density polyethylene resin were adhered substantially uniformly over the entire label surface. Table 1 shows the evaluation results for the delivery label (C2).

[0126]

Table 1

[0127] As shown in Table 1, it can be seen that for the delivery labels (E1) to (E3) of Examples 4 to 6 obtained using the pressure rolls (R-3) to (R-5) produced in Examples 1 to 3, the stability of the lamination process was good and the peeling of the thermal paper (base material) through the peelable portion could be easily performed with a small force.
