  An embodiment of a label with a wrap film opening function according to the present invention will be described with reference to the drawings. FIG. 1 is a top view showing an example of a label with a wrap film opening function according to the present invention, and FIGS. 2 (a), 2 (b), and 2 (c) are views of FIG. Is a schematic cross-sectional view taken along line XX, YY, and ZZ. Here, the label 90 with a wrap film opening function as a product label on which the printed matter A is mainly printed will be described as an example. However, the present application is not limited to this, and the purpose is to open the wrap film 10 only. It can also be applied to unsealed labels.

  As shown in FIGS. 1 and 2, the label 90 with a wrap film opening function according to the present invention includes a synthetic resin sheet layer 22 and an adhesive layer 20 provided on the back side of the sheet layer 22. Have. The label 90 with a wrap film unsealing function is formed with a knob portion 30, and the non-sticking region 32 is formed on the inner side of the knob portion 30, that is, on the sheet layer 22 on the extension line of the terminal end P of the knob portion 30. Is formed with a predetermined length up to the end Q. Moreover, when the label 90 with a wrap film opening function is a product label, the printed matter A is printed on the surface side of the sheet layer 22. 1A shows an example in which the knob 30 is formed so as to protrude from the side (outer periphery) of the label 90 with a wrap film opening function, and FIG. 1B shows the side of the label 90 with a wrap film opening function. An example is shown in which two notch portions 36 are formed inwardly from the side (outer periphery) and the knob portion 30 is formed by the notch portions 36.

  Further, the pressure-sensitive adhesive layer 20 in the knob part 30 and the non-sticking area 32 part is subjected to a non-sticking process, and a paste-killing layer 24 is formed as shown in FIG. As a result, the label 90 with the wrap film opening function is attached to the wrap film 10 via the pressure-sensitive adhesive layer 20 so that the non-adhesive treatment-adhering region 34 is adhered thereto, and the knob portion 30 subjected to the non-adhesive treatment. The non-sticking region 32 portion is not stuck to the wrap film 10. In addition, it is preferable to form the paste-killing layer 24 by printing and applying a well-known release material such as a silicon-containing varnish to the portions of the knob part 30 and the non-sticking region 32.

  There is no particular limitation on the outer shape of the label 90 with a wrap film opening function. In addition to general label shapes such as rectangles, rounded rectangles, ellipses, etc., various designs according to the demands and products of the orderer should be used. Can do. Further, the shape of the picking portion 30 is not particularly limited, but it is preferably a semi-ellipse or a rounded quadrangular shape that is easy for the unsealed person to pick. However, as shown in FIGS. 3A to 3D, it is preferable that the angle θ formed between both sides of the knob 30 and the outer periphery of the label 90 with the wrap film opening function is a right angle.

  3A and 3B show an example in which the knob 30 is formed so as to protrude from the outer periphery of the label 90 with a wrap film opening function, as in FIG. 1A. 3C, two notches 36 are formed from the outer side of the side 90 of the sheet layer 22, that is, the label 90 with a wrapping film opening function, to the inside as in FIG. 1B. The example which formed the knob | pick part 30 by the notch part 36 is shown. As shown in FIG. 3 (d), the knob portion 30 of the label 90 with a wrap film opening function forms the main body of the knob portion 30 by the two notch portions 36, and You may form a front-end | tip part slightly so that it may protrude from the outer periphery of the label 90 with a wrap film opening function. In addition, in the structure of Fig.3 (a), (b), since the knob | pick part 30 protrudes, an unsealing person can pick the knob | pick part 30 easily. Moreover, according to the structure of FIG.3 (c), since the knob | pick part 30 exists inside the outer periphery of the label 90 with a wrap film unsealing function, bending of the knob | pick part 30 at the time of transport of goods or a display is carried out. Breaking and the like can be prevented. Moreover, the margin part of the sheet | seat material at the time of manufacturing the label 90 with a wrap film opening function can be reduced, and the improvement of a picking number and the reduction of material cost can be aimed at. Moreover, according to the structure of FIG.3 (d), the label 90 with a wrap film opening function which has both advantages can be obtained.

  Still further, the label 90 with a wrap film unsealing function is, as shown in FIG. 3 (e), an anti-peeling piece connected to the sticking region 34 at a part of the side of the knob 30 formed by the notch 36. 37 may be provided. According to this configuration, the peeling preventing piece 37 can prevent the knob 30 from being lifted, and can further prevent or suppress the bending, tearing, or the like of the knob 30 during transportation or display of the above-described product. . In addition, this peeling prevention piece 37 is easily torn when the unsealing person picks the picking portion 30 and lifts it. Furthermore, the label 90 with the wrap film opening function may be formed on the inner side with a predetermined interval from the side of the label 90 with the wrap film opening function, as shown in FIG. good. According to this configuration, in addition to preventing the bent portion 30 from being bent or torn at the time of transportation or display of the product, the sticking region 34 is present in all directions of the picking portion 30 and the non-sticking region 32. It is possible to more effectively hold the wrap film 10 by the sticking region 34.

  For the pressure-sensitive adhesive layer 20 constituting the label 90 with a wrap film opening function, a well-known pressure-sensitive adhesive can be used, and among these, a CHR (homopolymer) -based aqueous acrylic emulsion pressure-sensitive adhesive is preferably used. Moreover, it is preferable to use the adhesive layer 20 with strong adhesiveness, and the adhesive strength is a test method according to JIS Z0237, and the adhesive strength to the plastic plate is about 7.6 N / 25 mm (6) .6 N / 25 mm to 8.6 N / 25 mm), and those having an adhesive strength of about 10.8 N / 25 mm (9.8 N / 25 mm to 11.8 N / 25 mm) in terms of interfacial fracture are particularly preferable. . And by this adhesive layer 20, the sheet | seat layer 22 and the wrap film 10 adhere | attach and integrate with a strong force, and the drawability of the wrap film 10 is inhibited. As a result, the wrap film 10 cannot be freely stretched and contracted, and is easily torn with a weak force substantially equal to that of the sheet layer 22 without exhibiting stretchability.

  Moreover, the sheet layer 22 which comprises the label 90 with a wrap film opening function can use a well-known synthetic resin sheet material. When the printed material A is formed on the sheet layer 22, the sheet layer 22 capable of printing the printed material A by a general printing method is used.

  The sheet layer 22 is preferably an anisotropic sheet having an easy tear direction that easily tears and a difficult tear direction that is difficult to tear. Many synthetic resin sheets are formed by stretching a synthetic resin slurry, and an easy tear direction and a difficult tear direction are formed by the direction and strength of the stretch. This manufacturing method is also used for a general wrap film 10, and thus the above anisotropy exists in many wrap films 10. This anisotropy is thought to be due to the fact that when the synthetic resin film is stretched in one direction while being heated to some extent, the molecules are arranged in the stretching direction and the strength increases, and many synthetic resin sheets including the wrap film 10 are included. In general, the short direction is the easy tear direction.

  And when an anisotropic sheet is used for the sheet layer 22, as shown in FIG. 1, the side of the knob part 30 of the label 90 with a wrap film opening function and the side of the non-stick area 32 are easily teared. It forms so that it may become a direction. A black arrow in FIG. 1 indicates the easy tear direction of the sheet layer 22. Thereby, the tearing direction in which the knob portion 30 is picked and pulled becomes the easy tear direction of the sheet layer 22. For this reason, when the knob | pick part 30 is pulled in the tearing direction, the sheet | seat layer 22 tears easily from the terminal P of the knob | pick part 30 as the starting point.

  In the case where a sheet material having no anisotropy or a sheet material having a weak anisotropy is used for the sheet layer 22, as shown in FIGS. It is preferable to provide a cut line 38 ′ along the side edge of the knob 30 or a cut line 38 ′ along both sides of the non-stick area 32. According to this configuration, even when a sheet material having no anisotropy or a sheet material having a low anisotropy tendency is used, the sheet layer 22 can be easily torn in the tearing direction. However, in this case, it is preferable to form the label 90 with the wrap film opening function so that the side of the knob portion 30 is in the easy tear direction of the wrap film 10. This will be described in detail later.

  Next, a configuration of a sheet material particularly suitable for the sheet layer 22 of the present invention will be briefly described. A sheet material suitable for the present invention comprises a polypropylene resin as a main component, and is composed of a base layer and three layers of two surface layers formed above and below the base layer. A sheet material suitable for the present invention is a sheet in which the base layer is stretched in the longitudinal direction (longitudinal direction), and then the surface layer is formed on the upper and lower surfaces of the base layer and is stretched in the lateral direction (short direction) together with the base layer. It becomes. Therefore, the base layer is stretched in both the long and short directions, and the upper and lower surface layers are stretched only in the short direction. Further, the base layer and the surface layer before stretching have fine voids, and these voids are also stretched in the stretching direction. Therefore, in particular, the voids in the upper and lower surface layers are stretched only in the short direction and become fine voids elongated in the short direction. Due to the presence of the fine gaps long in the short direction, the short direction of the sheet material becomes an easy tear direction in which the sheet material is easily broken. And in this sheet material suitable for this invention, the label 90 with a wrap film opening function is formed so that the side part of the knob | pick part 30 and the non-sticking area | region 32 may follow along the short direction which is an easy tear direction.

  In addition, the label 90 with a wrap film opening function according to the present invention is formed by firmly attaching the adhesive region 34 of the sheet layer 22 to the wrap film 10 and integrating them, and extending from the knob 30 and the non-adhesive region 32. The wrap film 10 stuck to the sticking area 34 is torn together with the sheet layer 22 from the disconnection as a starting point. Therefore, a certain area is required for the sticking region 34. Here, the preferable dimension of the sticking area | region 34 is demonstrated using FIG. In addition, FIG. 5 is the figure which applied the label 90 with a wrap film opening function based on this invention to the opening label. As a preferable dimension of the sticking area | region 34, the width L1 of the sticking area | region 34 of the both sides of the non-sticking area | region 32 shall be 15 mm or more. Moreover, Preferably length L2 from the terminal Q of the non-sticking area | region 32 in the tearing direction to the outer periphery of the label 90 with a wrapping film opening function shall be 30 mm or more. If it has the sticking area | region 34 about this dimension, it will become possible to ensure a sufficient area for holding | maintenance of the wrap film 10, the stretchability of the wrap film 10 will be prevented, and the wrap film 10 with the sheet | seat layer 22 will be prevented. It can be easily broken. In addition, this dimension value is the same also in the label 90 with a wrap film opening function as a product label.

  Moreover, in addition to forming the side part of the pick part 30 and the non-sticking area | region 32 along the easy tear direction of the sheet | seat layer 22, the label 90 with a wrap film opening function which concerns on this invention is a sticking destination. It is preferable to form the wrap film 10 so as to be along the easy tear direction. However, the packaging of the product 1 and the sticking of the label with the wrap film 10 are often performed at the delivery destination. Therefore, the easy tear direction of the wrap film 10 packaging the product and the sticking direction of the label at the delivery destination are grasped in advance, and the side of the knob part 30 and the non-sticking area 32 is the wrap film 10 side. It is preferable to form the label 90 with a wrap film opening function so that it may become the same as an easy tear direction.

  Here, it is assumed that a label 90 with a wrap film opening function having a printed matter A as shown in FIG. 6 is manufactured. For example, when the easy tearing direction of the wrap film 10 at the time of product packaging is the direction of the white arrow in FIG. 6A, the side portions of the knob part 30 and the non-sticking region 32 are easy on the wrap film 10. The direction of the printed material A is set so as to be the tear direction, that is, the short direction of the product 1. At this time, the easy tear direction of the sheet layer 22 indicated by the black arrow in FIG. 6 is the same as the easy tear direction of the wrap film 10. Therefore, when the easy tear direction of the sheet layer 22 is the short direction of the sheet material, the printing direction of the label 90 with the wrap film opening function is the direction shown in FIG. Moreover, when the easy tear direction of the wrap film 10 at the time of product packaging is the direction of the white arrow in FIG. 6C, the side portions of the knob portion 30 and the non-stick area 32 are easily teared. The direction of the printed matter A is set so as to be the direction, that is, the longitudinal direction of the product 1. At this time, the easy tear direction of the sheet layer 22 indicated by the black arrow in FIG. 6 is the same as the easy tear direction of the wrap film 10. Therefore, when the easy tear direction of the sheet layer 22 is the short direction of the sheet material, the printing direction of the label 90 with the wrap film unsealing function is the direction shown in FIG. In addition, as shown in FIG. 6, it is preferable to form the knob | pick part 30 along the pattern of the printed matter a so that the design property of the printed matter A of the label 90 with a wrap film opening function may not be impaired.

  Next, the usage method of the label 90 with a wrap film opening function which concerns on this invention is demonstrated. Here, the label 90 with a wrap film opening function from which the knob part 30 protrudes will be described as an example, but this method of use is a wrap film opening function of another knob part 30 shape shown in FIGS. The same applies to the attached label 90.

  First, as shown in FIG. 7A, the label 90 with a wrap film opening function is in a state of being attached to the wrap film 10 in which the product 1 is packaged. The label 90 with a wrap film opening function is attached to the wrap film 10 with the pressure-sensitive adhesive layer 20 in the sticking region 34, and the pinching portion 30 and the non-stick region 32 are attached to the wrap film 10 due to the presence of the paste-killing layer 24. Will not stick.

  Next, as shown in FIG. 7B, the unsealing person pulls the knob 30 in the tearing direction. As a result, the sheet layer 22 is torn at the boundary between the sticking region 34 and the non-adhesive region 32 starting from the end P of the knob 30. In addition, since the tearing direction of the knob part 30 is the easy tearing direction of the sheet layer 22, the sheet layer 22 is easily torn between the sticking region 34 and the non-adhesive region 32.

  When the unsealing person further pulls the knob 30, the tear line starting from the end P reaches the end Q of the non-adhesive region 32 as shown in FIG. Then, when the unsealing person pulls the knob 30 further, as shown in FIG. 8B, the sheet layer 22 of the sticking region 34 located at the terminal end Q is between the sticking region 34 and the non-adhesive region 32. Break from the tear line. At this time, since the sticking region 34 firmly holds the wrap film 10, the stretchability, which is a feature of the wrap film 10, is prevented and cannot be stretched or shrunk easily together with the sheet layer 22. And the tearing of the lap | wrap film 10 expands by pulling the knob | pick part 30 further, The wrap film | membrane 10 can be easily opened by using this as an opening end.

  Next, an example of the manufacturing method of the label 90 with a wrap film opening function of this invention is demonstrated using FIG. In addition, the manufacturing method of the label 90 with a wrap film opening function which has the printed matter A is demonstrated here. First, an original fabric roll 94 a around which a strip-shaped sheet material 94 is wound is installed in the label manufacturing apparatus 100. The sheet material 94 includes the above-described sheet layer 22, the pressure-sensitive adhesive layer 20, and the separator 26 that has been subjected to a release treatment and is temporarily attached to the pressure-sensitive adhesive surface of the pressure-sensitive adhesive layer 20. Then, the sheet material 94 is conveyed to the back surface printing unit 40 of the label manufacturing apparatus 100 by the conveyance roller. The back surface printing unit 40 first peels off the separator 26 of the conveyed sheet material 94. Next, the sheet is conveyed to the back surface printing machine 44, where a well-known release material such as a silicon-containing varnish is printed and applied to the pressure-sensitive adhesive layer 20 of the sheet material 94 in the shape of the knob 30 and the non-sticking area 32. As a result, the paste-killing layer 24 is formed on a part of the pressure-sensitive adhesive layer 20 corresponding to the knob part 30 and the non-sticking region 32. Next, the separator 26 peeled off at the previous stage is temporarily attached to the adhesive layer 20 on which the paste-killing layer 24 is formed. Next, the sheet material 94 is conveyed to the surface printing machine 46, where a predetermined printed matter A is printed on the surface of the sheet layer 22. In the case of multicolor printing or the like, a plurality of the surface printing machines 46 are installed. The sheet material 94 on which surface printing has been performed is conveyed to a punching machine 48 and punched into the shape of a predetermined label 90 with a wrap film opening function provided with a knob 30. At this time, punching is not performed on the separator 26, and the label 90 with a wrap film opening function is carried on the separator 26. The punched sheet material 94 is wound after the unnecessary unnecessary blank portion of the sheet layer 22 'is peeled off. As a result, a label roll 92 having a plurality of wrap film opening function labels 90 carried on the separator 26 is completed. And this label roll 92 is delivered, for example to an order receiving party, and is stuck on the wrap film 10 which wrapped the goods 1 as mentioned above.

  As described above, the label 90 with a wrap film opening function according to the present invention first tears the sheet layer 22 starting from the end P of the knob 30 and then the sheet layer 22 at the end Q of the non-adhesive region 32. The wrap film 10 is torn together with the sheet layer 22 in the sticking region 34 using the tear line as a starting point (cut). At this time, since the sticking region 34 is firmly stuck and integrated with the wrap film 10, the stretchability of the wrap film 10 is prevented and plastic deformation cannot be performed, and the wrap film 10 together with the sheet layer 22. The sheet layer 22 is easily broken with a weak force substantially equal to that when the sheet layer 22 is broken.

  Moreover, the label 90 with a wrap film opening function which concerns on this invention pays attention to the easy tear direction and hard tear direction which exist in the sheet | seat layer 22 and the wrap film 10, and the side part of the knob | pick part 30 and the non-sticking area | region 32. Is formed so as to be in an easy tear direction of the sheet layer 22 and the wrap film 10. Thereby, tearing of the sheet | seat layer 22 and the wrap film 10 can be performed very easily and easily.

  In addition, the structure of the label 90 with a wrap film opening function shown in this example is an example, and the shape and dimensions of each part such as the label 90 with a wrap film opening function and the knob part 30 and the material of each layer are as described above. It is not limited. Furthermore, the present invention can be modified and implemented without departing from the scope of the present invention.

(4) The label 90 with a wrapping film opening function according to (1) or (2) above, wherein the knob portion 30 is formed inside at a predetermined interval from the side of the sheet layer 22. By providing, the above-mentioned problems are solved.
(5) Providing the label 90 with a wrapping film opening function according to (3) or (4) above, which has a peeling prevention piece 37 connected to the sticking region 34 on the side of the knob 30. Thus, the above problem is solved.
( 6 ) The sheet layer 22 is composed of a base layer and a surface layer disposed above and below the base layer, the base layer is stretched in the long and short direction and the surface layer is stretched in the short direction and formed into a sheet, The surface layer is provided with fine gaps that are long in the short direction generated during stretching in the short direction, an easy tear direction that is easily broken in the short direction is formed by the fine gaps, and the side of the knob portion 30 is By providing the label 90 with a wrap film opening function according to any one of the above (1) to (5) , which is formed along the easy tear direction, the above-mentioned problems are solved.

Further, the sheet layer 22 has a Eki裂direction to easily tear, Ru using anisotropic sheet having a tear hardly fire crack direction. Many synthetic resin sheets are formed by stretching a synthetic resin slurry, and an easy tear direction and a difficult tear direction are formed by the direction and strength of the stretch. This manufacturing method is also used for a general wrap film 10, and thus the above anisotropy exists in many wrap films 10. This anisotropy is thought to be due to the fact that when the synthetic resin film is stretched in one direction while being heated to some extent, the molecules are arranged in the stretching direction and the strength increases, and many synthetic resin sheets including the wrap film 10 are included. In general, the short direction is the easy tear direction.

Then, you have use anisotropic sheet in the sheet layer 22, as shown in FIG. 1, the sides and the Eki裂direction of wrap film opening and knob of saw unit 30 side of the functional Labeled 90 unadhesive region 32 It forms so that it becomes. A black arrow in FIG. 1 indicates the easy tear direction of the sheet layer 22. Thereby, the tearing direction in which the knob portion 30 is picked and pulled becomes the easy tear direction of the sheet layer 22. For this reason, when the knob | pick part 30 is pulled in the tearing direction, the sheet | seat layer 22 tears easily from the terminal P of the knob | pick part 30 as the starting point.

In the case of using the anisotropic tendency is weak sheet material to a sheet layer 22, as shown in FIG. 4 (a), (b) , the end of the knob portion 30, the side of the knob portion 30 It is preferable to provide cut lines 38 along the sides or cut lines 38 ′ along both sides of the non-stick area 32. According to this structure, even when the tendency of the anisotropy is used a weak sheet material, the sheet layer 22 can be easily torn in the tear direction. However, in this case, it is preferable to form the label 90 with the wrap film opening function so that the side of the knob portion 30 is in the easy tear direction of the wrap film 10. This will be described in detail later.
