Abstract
A thermal plastic film bag structure having front and rear walls, gusseted side walls and a sealed bottom. This bag which has a tendency to form holes in the bottom at the seal transition point between the four layers of the gusset and the two layers of the central region of the bag is improved by providing seal areas, e.g. circular seals which are located slightly above the bottom seal line and slightly inside of the vertical line formed by the innermost reach of the gussets on both sides of the bag. The seal areas relieve strain at the weak regions in the bottom of the bag.
