bag

Abstract

This product is a bag with an expandable function. The zipper is located near the edge of the bag, not in the center, and by opening the zipper, the width of the gusseted bag can be further expanded. Unlike bags without a gusset that have a zipper in the center and can be expanded, this product allows the gusseted bag to be expanded. For example, as shown in the reference diagram showing the bag in use, even a gusseted bag with a PET bottle holder pocket on the side can be further expanded in width, thereby increasing the storage space inside the bag.
