Packaging bags

Abstract

As shown in [Reference Figure 2, showing the state of use], this product is a packaging bag that can stand on its own even after opening and can be used as a container as is. In addition, as shown in [Partially enlarged view of the lower side of the side 1] and [Partially enlarged view of the lower side of the side 2], the legs of this product are welded only at the semicircular crimped areas on both sides, and the areas above and below are non-crimped areas that are not welded. This relieves stress caused by distortion of the packaging bag, improving stability when it stands on its own. Furthermore, further stability can be obtained by peeling off the semicircular crimped areas and spreading the legs to support them as shown in [Reference Figure 3, showing the state of use].
