Description

  The present invention relates to a label attached to a packaging film for packaging a product, and more particularly to a label with a film opening function that tears the packaging film to form an opening end.

  Conventionally, there is a packaging form where products such as food are placed on a tray such as polystyrene foam, plastic, paper, etc., covered with a transparent wrap film from above, and fixed on the back side by sticking the content display label or adhesiveness of the wrap film Generally done. In addition, as a packaging form for desserts such as yogurt and pudding and cup noodles, a packaging form in which the end of the shrink film is thermally welded after wrapping the product with a transparent shrink film is also generally performed. It has been broken. However, these packaging films have a certain degree of strength and stretchability, and in particular, the shrink film has a certain degree of thickness and a high strength because of thermal welding. For this reason, there is a problem that the person who opened the product cannot easily tear it and feels stress at the time of opening. In addition, particularly elderly people with weak power may not be able to open unless they use a blade. Regarding this problem, the following [Patent Document 1] discloses an invention in which an opening label is attached to a wrap film and the opening label is pulled left and right to break the wrap film.

  An embodiment of a label with a film opening function according to the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a usage example of a label with a film opening function according to the present invention. Moreover, Fig.2 (a) is a front view which shows an example of the label with a film opening function which concerns on this invention, FIG.2 (b) is a schematic cross section in the state XX stuck to the packaging film. is there. 2 (a) and 2 (b) show a label 90 with a film opening function that also serves as a product label having a printed matter A, but the present invention is not limited to this. For example, FIG. As shown to c), you may stick the label 90 with a film opening function which concerns on this invention to the packaging film 10 separately from a product label.

  The label 90 with a film opening function according to the present invention is affixed to a packaging film 10 for wrapping a product 1, and a sheet layer 22 made of a synthetic resin having an adhesive layer 20 on the back surface side, and the sheet layer 22. The film tearing part 30 comprised by the cutting line 36 formed in this. And since the adhesive layer 20 of the label 90 with a film opening function sticks to the packaging film 10, the label main-body part 34 and the film tearing part 30 of the label 90 with a film opening function hold | maintain the packaging film 10 closely. . The outer shape of the label 90 with the film opening function is not particularly limited, and in addition to a general label shape such as a rectangle, a rounded quadrangle, an ellipse, etc., it has various designs according to the orderer's request and product. be able to.

  Further, the label 90 with the film opening function is the film of the label 90 with the film opening function at a portion where the inner surface of the packaging film 10 is separated from the product 1, that is, a portion where a gap exists between the packaging film 10 and the product 1. It is preferable to attach so that the tearing part 30 may be located. In addition, as a specific example of the part in which a gap exists between the product 1 and the packaging film 10, a cup between the product 1 and the product 1 in the packed product shown in FIG. It is a bottom surface of noodles, etc., and is a portion where a gap is generated in the packaging film 10 due to the irregularities of the outer shape of the product 1 or the like.

  Further, the film tearing portion 30 includes a tearing end portion 32 that becomes a tearing end of the packaging film 10, a side edge 33 that extends from both sides of the tearing end portion 32, and a tearing end portion 32 of the side edge 33. Has a stopper portion 38 formed at the opposite end. And it is preferable to form the length of the tearing edge part 32 which comprises the film tearing part 30 a little longer than the width | variety of a person's finger | toe. The length of the film tearing portion 30, that is, the length from the tip of the tearing end portion 32 to the end of the side 33 is preferably the length of a human fingertip, that is, about 1 cm to 2 cm. Moreover, the stopper part 38 formed in the edge part of the side edge 33 inhibits tearing of the sheet | seat layer 22, and is formed when the cutting line 36 curls outside. The film tearing portion 30 is preferably substantially arc-shaped as shown in FIG. 2, but is not particularly limited to this, and is substantially U-shaped as shown in FIG. Also good. Also, other shapes may be used. However, the tearing end portion 32 is positioned in a direction substantially equivalent to the easy tearing direction of the packaging film 10 to be described later, and has a shape in which the packaging film 10 is easily torn by pressing against the tearing end portion 32. Furthermore, it is preferable to have a cut line 37 of about 1 mm to 2 mm formed on both sides of the tearing end portion 32 toward the outside (the label main body portion 34 side).

  Here, the anisotropy of the packaging film 10 to which the label 90 with a film opening function is attached will be described. A general synthetic resin sheet is formed by stretching a synthetic resin slurry, and there are an easy tear direction that easily breaks due to the direction and strength during stretching, and a difficult tear direction that is difficult to tear. 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 aligned in the stretching direction and the strength is increased, and many of them include the packaging film 10 (wrap film, shrink film). In the synthetic resin sheet, the short direction is the easy tear direction.

  And the label 90 with a film opening function which concerns on this invention is affixed so that the direction of the tearing edge part 32 may become a direction substantially equivalent to the easy tear direction (indicated by the white arrow in FIG. 2) of the packaging film 10. To wear. For example, when the film tearing portion 30 is substantially arc-shaped, the film is attached so that the tangential direction of the substantially distal end portion of the tearing end portion 32 is substantially the same direction as the easy tearing direction of the packaging film 10. Moreover, when the film tearing part 30 is a substantially U-shaped thing, it sticks so that the direction of the tearing edge part 32 may become a direction substantially equivalent to the easy tearing direction of the packaging film 10. FIG. In addition, when packaging of the product 1 by the packaging film 10 and label sticking are performed at the delivery destination, the easy tear direction of the packaging film 10 when packaging the product, and the label sticking direction at the delivery destination It is preferable that the label 90 with the film opening function is formed so that the direction of the tear end portion 32 is the same as the easy tear direction of the packaging film 10. As described above, it is ideal that the direction of the tear end portion 32 coincides with the easy tear direction of the packaging film 10, but the direction of the tear end portion 32 and the easy tear direction of the packaging film 10 are somewhat different. Even if it is displaced, the film tearing portion 30 functions sufficiently. In particular, when the film tearing portion 30 is substantially arc-shaped, there is a width in the tangential direction of the tearing end portion 32, so that the allowable range of displacement with respect to the easy tearing direction of the packaging film 10 is wide, and for relatively large deviations. Even with an excellent opening function.

  Moreover, the sheet layer 22 which comprises the label 90 with a film opening function can use the well-known synthetic resin sheet material. In addition, when forming the printed matter A on the sheet layer 22, the sheet layer 22 that can form the printed matter A by a general printing method is used. Moreover, the sheet layer 22 used for the label 90 with a film opening function uses the anisotropic sheet | seat which has the easy tear direction which is easy to tear similarly to the above-mentioned packaging film 10, and the difficult tear direction. Is preferred. And when using an anisotropic sheet | seat for the sheet | seat layer 22, as shown in FIG. 2, the direction of the side 33 of the film tearing part 30 is the easy tear direction of the sheet | seat layer 22 (it shows by the black arrow in FIG. 2). It forms so that it becomes.

  Here, 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 film opening function is formed so that the short direction which is an easy tear direction may turn into the direction of the side 33 of the film tearing part 30. FIG.

  The pressure-sensitive adhesive layer 20 formed on the back surface of the sheet layer 22 can be a well-known pressure-sensitive adhesive, and among them, a CHR (homopolymer) 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 the sheet layer 22 and the packaging film 10 are adhered and integrated with a strong force by the pressure-sensitive adhesive layer 20, thereby inhibiting the stretchability of the packaging film 10. Thereby, the packaging film 10 cannot be freely stretched and contracted between the label main body 34 and the film tearing portion 30, and is easily torn with a weak force along the cutting line 36 without exhibiting stretchability. . By this tearing, a hole serving as an unsealed end is opened in the packaging film 10.

  Next, the usage method of the label 90 with a film opening function which concerns on this invention is demonstrated. Here, the shrink film 10 is used as the packaging film 10 for explanation. First, as shown in FIG. 1, the label 90 with a film opening function is in a state of being attached to a shrink film 10 (packaging film 10) in which a product 1 is packaged. At this time, it sticks so that the film tearing part 30 may be located in the part which a clearance gap produces between the shrink film 10 and the goods 1. FIG. The easy tear direction of the shrink film 10 at this time is the direction indicated by the white arrow in FIG. 1 and is substantially the same direction as the tear end portion 32 of the label 90 with the film opening function.

  Next, the unsealing person presses the tearing end portion 32 of the film tearing portion 30 with a finger or a coin. As described above, the label main body 34 and the broken end 32 hold the shrink film 10 with the cutting line 36 interposed therebetween. And the direction of the tearing edge part 32 is a direction substantially equivalent to the easy tear direction of the shrink film 10. FIG. Therefore, when the unsealing person depresses the tear end portion 32, the label main body portion 34 and the tear end portion 32 inhibit the stretchability of the shrink film 10, and the shrink film 10 has the tear end portion 32 in the easy tear direction. Tear easily along. In particular, when the film tearing portion 30 is substantially arc-shaped, the pressing force of the unsealing person is concentrated in the vicinity of the tip of the tearing end portion 32, so that the shrink film 10 can be torn with a weaker force. The shrink film 10 that has been torn along the broken end portion 32 is torn along the cutting line 36 on the side 33 continuously. Note that the direction of the side edge 33 corresponds to the difficult tear direction of the shrink film 10, but the shrink film 10 has already been torn at the tear end portion 32, and the label main body portion 34 and the side edge 33 are adhered. Since the stretchability is hindered, it is easily broken along the side 33. Thereby, an opening H is formed in the shrink film 10 as shown in FIG.

  Further, as shown in FIGS. 4B and 4C, the breaking end portion 32 may be formed by a broken cutting line 36 'formed intermittently. According to this structure, since the tearing edge part 32 is partially connected with the label main-body part 34 side, the accidental tearing of the shrink film 10 at the time of goods transportation or display can be prevented.

  Then, the tearing of the shrink film 10 due to the pressing of the opening person is temporarily stopped at the stopper portion 38. Here, when the stopper portion 38 is not present, the sheet layer 22 is greatly broken in the direction of the side 33 together with the shrink film 10 at the same time as the shrink film 10 is broken, and the opener's finger or the like is pushed into the shrink film 10. Therefore, there is a risk of damaging the product 1 or hurting the finger. In particular, when the product 1 is a food product and is not individually packaged, the rushed finger may come into direct contact with the food product, which is not preferable for food hygiene. Further, when the products 1 are individually packaged, no sanitary problem occurs, but it is not preferable that the fingers rush into the shrink film 10 against the will of the opener. In this respect, since the label 90 with the film opening function according to the present invention has the stopper portion 38 curled outside at the end of the side 33, the tearing of the sheet layer 22 is temporarily stopped and carelessly performed. There is no expansion.

  Then, when the person who wants to open the container desires further enlargement of the opening hole H, for example, a finger is put into the opening hole H and the label main body 34 located between the two cut lines 37 is pulled up. The pulling direction at this time is the easy tear direction of the sheet layer 22. Therefore, the sheet layer 22 is easily torn starting from the score line 37. Further, since the shrink film 10 is stuck and held on the label main body 34 of the sheet layer 22 and the stretchability is hindered, it is easily broken together with the sheet layer 22. Thereby, the opening hole H of the shrink film 10 expands, and the shrink film 10 can be easily opened using this as an opening end. Note that the method for opening the shrink film 10 is not limited to this. The finger may be put into the opening hole H to tear the shrink film 10, or the film tearing portion 30 side may be picked and pulled up, and the stopper portion The sheet layer 22 and the shrink film 10 may be forcibly broken from 38 and opened.

  Here, it is assumed that the label 90 with a film opening function having the printed matter A as shown in FIG. 5 is manufactured. For example, when the easy tear direction of the shrink film 10 during product packaging is the direction of the white arrow in FIGS. 5A and 5C, the label 90 with the film opening function is shown in FIGS. As shown in FIG. 5, the film tearing portion 30 is formed in the direction in which the tearing end portion 32 becomes the easy tearing direction of the shrink film 10. At this time, the easy tear direction of the sheet layer 22 indicated by the black arrow in FIG. 5 is the direction of the side 33 of the film tearing portion 30. 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 film opening function shown in FIG. 5A is the direction shown in FIG. Moreover, the printing direction of the label 90 with a film opening function shown in FIG.5 (c) becomes a direction shown in FIG.5 (d). In addition, as shown in FIG. 5, you may form printed matter a, such as "PUSH" and "push" which suggest the operation | movement which tears a packaging film to an opener in the film tearing part 30. As shown in FIG.

  Next, an example of the manufacturing method of the label 90 with a film opening function of this invention is demonstrated using FIG. In addition, the manufacturing method of the label 90 with a 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 a sheet layer 22 including the pressure-sensitive adhesive layer 20, and a 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 by the conveyance roller to the label surface printing machine 46 of the label manufacturing apparatus 100, 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 label surface printing machines 46 are installed. The sheet material 94 on which the label surface has been printed is conveyed to a punching machine 48 to form a film tearing portion 30 and punched into a predetermined shape of the label 90 with a film opening function. At this time, punching is not performed on the separator 26, and the label 90 with the 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. Thereby, the label roll 92 in which the plurality of labels 90 with the film opening function are carried on the separator 26 is completed. The label roll 92 is delivered to, for example, an order receiving party, and is stuck on the packaging film 10 on which the product 1 is packaged.

  As described above, the label 90 with the film opening function according to the present invention has the film tearing portion 30 formed by the cutting line 36, and the tearing end portion 32 of the film tearing portion 30 is the packaging film 10. It sticks so that it may become the easy tear direction. Then, when the unsealing person presses down the tearing end portion 32, the tearing end portion 32 and the label main body portion 34 adhered to the packaging film 10 inhibit the stretchability of the packaging film 10, and the packaging film 10 has the tearing end portion. It tears easily along the part 32. Next, the packaging film 10 is torn along the side edge 33, whereby an opening hole H is formed in the packaging film 10. Further, the tearing of the packaging film 10 is temporarily stopped at the stopper portion 38 formed at the end portion of the side 33. Thereby, the opening hole H does not expand carelessly. And a person who opens can use this opening hole H as an opening end, and can open the packaging film 10 easily and reliably.

  In addition, the structure of the label 90 with a film opening function shown in this example is an example, and the shape, dimension, layer structure, manufacturing method, etc. of each part of the label 90 with a film opening function and the film tearing part 30 are as described above. The present invention is not limited, and the present invention can be modified and implemented without departing from the gist of the present invention.
