Description

  The present invention relates to a product packaging body and a packaging bag, and in particular, includes a packaging bag including a front sheet portion, a back sheet portion, and a bottom sheet portion, and a three-dimensional product accommodated in the product accommodating portion of the packaging bag. The present invention relates to a product packaging body and a packaging bag used for the product packaging body.

  For example, as a product packaging body that accommodates small articles such as cosmetics and stationery and can be easily displayed, a package containing a commodity in a packaging bag made of a transparent film material, preferably made of synthetic resin, is often used. In such a product package, the packaging bag is configured to include a front sheet portion and a back sheet portion, and the peripheral edge portion is cut by heat sealing or the like, or while thermally welding the film material. By simply joining together, a product storage section for storing products is formed in the packaging bag.

  Further, when a three-dimensional product is accommodated in the packaging bag, a space having a size corresponding to the thickness of the product is easily formed in the product accommodating part sandwiched between the front sheet part and the back sheet part. It is desirable to make the bottom sheet portion folded so as to have a flat V-shaped cross-sectional shape, with the open side of the V-shaped cross-section facing downward and the front sheet portion and the back sheet. There is also known a product package using a packaging bag sandwiched between and attached to the bottom part of the part (see, for example, Patent Document 1).

  In the product packaging body using the packaging bag including these bottom sheet portions, the edge portions on both sides of the bottom sheet portion are provided between the side edge portions on both sides of the front sheet portion and the side edge portions on both sides of the back sheet portion. A product container is formed in the packaging bag by sandwiching them and joining them together, and a bottom surface having an inverted V-shaped cross-section when a three-dimensional product is stored in the product container The portion between the edge portions on both sides joined to the front sheet portion and the back sheet portion of the seat portion is spread outward and deformed, so that the portion between the edge portions on both sides of the display shelf As a flat state that can be placed on the placement surface, the product package can be displayed independently.
