包装袋はしっかりと自立する。The product packaging bag of the present invention has a solid bag body,
It is preferable to print only on the tongue. By making the bag plain and printing only on the tongue, you can easily observe the products stored in the bag without being obstructed by the printing, and the letters printed on the tongue You can read clearly without being disturbed by. In the product packaging bag of the present invention, the tongue may be a tongue with synthetic paper. By using the tongue piece with the synthetic paper, the appearance and handleability of the product packaging bag can be improved. In the product packaging bag of the present invention, it is preferable that the inner surface of the bag body be subjected to antifogging treatment. By carrying out the antifogging treatment on the inner surface of the bag body, even if a product having a high water content is stored, the inner surface of the bag body will not be fogged and the stored product can be easily observed. The antifogging treatment method is not particularly limited, but for example, 6 parts by weight of colloidal silica, 2 parts by weight of colloidal alumina, and 0.1 parts by weight of anionic surfactant are added to 100 parts by weight of water, and further necessary. According to the above, a viscosity modifier may be added to improve the coating performance, and the film surface can be coated by spraying. In the product packaging bag of the present invention, at least one surface of the tongue piece is laminated with the same kind of plastic as the bag body surface, and on the laminated surface, one film in the upper edge opening of the bag body is heated over the entire width direction of the bag body. It is welded. By making the laminated surface of the tongue piece and the surface of the bag body of the same kind of plastic, the tongue piece and the bag body can be firmly heat-welded. The bag body can be made of non-laminated plastic film and the bag material and tongue laminate material can be the same type of plastic, or the outer surface of the bag body and at least one side of the tongue piece can be laminated with the same type of plastic. You can also do it. When the product packaging bag of the present invention is used, the upper edge opening of the bag is opened to store the product, the release film covering the pressure-sensitive adhesive layer is removed, and the tongue piece is folded back to the upper edge opening. , A pressure-sensitive adhesive layer for sealing is used for sealing. When the bottom edge of the bag is provided with a V-shaped gusset fold, the V-shaped gusset fold is opened to form a flat bottom, so that the product packaging bag is firmly self-supporting.
