Description

  The present invention relates to a packaging bag made of a resin film used for packaging confectionery or the like, which has an enhanced appeal to consumers.

  Conventionally, in Patent Document 1 below, a resin film is used as a raw material, a bag body in which a product is stored, and a band material covering a part of the surface thereof are formed, and the bag body and the band material are welded at both ends. In addition, a packaging bag in which a label for displaying a product name or the like is attached to a band is described.

Japanese Utility Model Publication No. 6-354 (Claims 3, 7 and 8)

  However, in the case of packaging bags such as those mentioned above, even when a campaign with a limited period of time is used, even if a label printed with a product advertisement is affixed to the band material, the appeal will be poor and the printing of the bag will be completely changed. Then, there is a problem that it takes a great deal of cost to remake the printing plate.

  Then, this invention makes it a subject to provide the packaging bag made from the resin film excellent in the appeal property to a consumer at low cost.

  In order to solve the above-mentioned problems, the present invention is a resin film packaging bag comprising a bag body in which a product is stored and a band material covering a part of the surface thereof, and the bag body and the band material are welded at both ends. In this case, different patterns are printed on the bag body and the band material, and the overlapping portion of these patterns moves relatively with the displacement of the bag body and the band material, and the pattern appearing on the surface of the band material changes. I did it.

  In this packaging bag, when the band material is shifted with respect to the bag body, the pattern that appears on the surface of the band material changes dynamically, so it can be visually interesting and attract consumers' interest. Can be obtained, and an excellent appeal effect can be obtained.

  Further, since the pattern can be changed by simply applying a partial printing to the bag body and adding the band material by utilizing the conventional bag making process, it is possible to suppress an increase in cost.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  As in the first embodiment shown in FIG. 1, this packaging bag is made of a resin film such as polyethylene or polypropylene, and a bag body 1 in which a product is accommodated and a band covering a part of the surface thereof. It is comprised from the material 2.

  In manufacturing the packaging bag, as shown in FIG. 7, the film s forming the bag body 1 is unwound from the take-up roll A, and the film t forming the band material 2 is unwound from the take-up roll B to be folded in half. The film t is overlaid on the surface of the film s.

  Then, the films s and t are thermally welded at the longitudinal seal portions 3 which are both ends of each packaging bag, and at the same time, the films s and t are cut at the center of the seal portion 3.

  Thereafter, as shown in FIG. 1, the upper and lower portions of the bag body 1 are sequentially sealed with a lateral seal portion 4 before and after the product is stored in the bag body 1.

  Here, prior to bag making, the bear face 5 is printed on the film of the band material 2 so that the eye hole portion 6 and the mouth hole portion 7 are transparent, and the film of the bag body 1 The bear's open eyes 6a and mouth 7a and closed eyes 6b and mouth 7b are printed side by side.

  In this packaging bag, as shown in FIG. 1 (a), when the bag body 1 and the band material 2 are not displaced, the eyes 6a and the mouth 7a opened from the eye hole portion 6 and the mouth hole portion 7 of the bear are transmitted. The closed eyes 6b and the mouth 7b are blocked by the printing of the face 5 and cannot be seen.

  On the other hand, as shown in FIG. 1 (b), when the consumer holds the packaging bag and shifts the band 2 laterally with respect to the bag body 1, the bag is closed from the eye hole 6 and the mouth hole 7 of the bear. The eyes 6b and the mouth 7b are seen through, and the opened eyes 6a and the mouth 7a are blocked by the printing of the face 5 and become invisible.

  In this way, in the packaging bag, when the band material 2 is shifted with respect to the bag body 1, the facial expression of the bear that appears on the surface of the band material 2 dynamically changes, so that the visual feeling is interesting, It is possible to attract consumers' interests and obtain an excellent appeal effect.

  Moreover, since the design can be changed by simply printing the bag body 1 by using the conventional bag making process and adding the band material 2, the cost increase can be suppressed.

  By the way, various variations of the pattern applied to the packaging bag are conceivable. For example, as in the second embodiment shown in FIGS. 2 and 3, the appearance 8 a before peeling the oranges is printed on the film of the strip 2, and the orange cuts 8 b are printed on the film of the bag 1. You may keep it.

  In this packaging bag, as shown in FIG. 3 (a), the orange cut 8b is not obstructed by the outer appearance 8a in a normal state, and as shown in FIG. When 2 is shifted to the side, the cut 8b appears, and the change in the purchase can increase the willingness to purchase the product.

  Also, as in the third embodiment shown in FIGS. 4 and 5, the birdcage 9 is printed on the film of the band material 2, and the vertical stripes 10 corresponding to the distance between the bars of the birdcage 9 on the film of the bag 1, The bird 11 may be printed.

  In this packaging bag, as shown in FIG. 5A, between the bars of the birdcage 9 is normally closed with vertical stripes 10 as shown in FIG. 5B, and as shown in FIG. When 2 is shifted to the side, the bird 11 appears from between the bars of the birdcage 9, so that the change can increase the willingness to purchase goods.

  Further, as in the fourth embodiment shown in FIG. 6, vehicle division diagrams 12 and 13 in which the Shinkansen train and the cruiser are divided into horizontal stripes may be printed on the film of the band material 2 and the bag body 1. .

  In this packaging bag, as shown in FIG. 6 (a), the symbol of the Shinkansen train is normally displayed, and as shown in FIG. 6 (b), the band 2 is shifted vertically with respect to the bag body 1. At that time, the cruiser's design is displayed, so that the change can increase the willingness to purchase the product.

  In each of the above embodiments, a four-side sealed packaging bag is exemplified, but a three-sided or two-side sealed packaging bag or a pillow type packaging bag is also added with a band material sticking process to the conventional bag making process. And the same structure which changes the pattern which appears on the surface of a strip | belt material with the shift | offset | difference of the bag body and strip | belt material which printed the different design is applicable.
