Abstract
A packing bag is formed by sealing longer side edges, and by sealing V shaped folded sheets to the shorter sides. A portion of the longer side edges is left unsealed to form an inlet port. A protected cylinder or handle may be attached to overlie the inlet port. Opposed notches are formed on both sides of the cylinder or handle to facilitate opening of the bag.
