Document Type and Number:
Japanese Patent JP2017100807
Kind Code:

Abstract:
PROBLEM TO BE SOLVED: To provide a bag container that facilitates bag-making processing such as heat welding and creasing, has optimal rigidity (flexibility) with a desired film thickness, and has high transparency, in other words, that imparts luxury compared to a conventional bag container.SOLUTION: A bag container 100 is formed of at least one sheet. The sheet contains a non-stretched PET film layer of which at least one surface is exposed as at least any one of a base material layer and an adhesive layer, and has a joined portion 182 formed by joining the non-stretched PET film layers. The bag container is formed by folding and joining at least one sheet containing the non-stretched PET film layer. In the bag container, the non-stretched PET film has adequate rigidity (flexibility) and high transparency, and accordingly can achieve functions of the bag container which films formed of other synthetic resin materials cannot achieve, in other words, characteristic functions such as high toughness, self-supporting, folding and advertisement use.SELECTED DRAWING: Figure 1
