Gusseted bag made of a composite plastic tissue

摘要

A side-gusset bag has a front panel, a rear panel, and side gussets between the front panel and the rear panel and connected to the front panel and rear panel by edge folds. The plastic film/fabric laminate has a polymer film on an outer surface of the bag and a fabric connected to the polymer film and made of polymer ribbons on an inner surface of the bag. A flap of the front panel and side gusset flaps between the flap of the front panel and the rear panel are folded onto the rear panel to form a bottom gusset to which they are connected. Corner weld seams bond the fabric surfaces of the side gussets on the inner surface of the bag to the adjacent fabric surfaces of the front panel or rear panel and an acute angle toward the bottom gusset.
