Abstract
A bag of tubular form closed at one end and partially closed at the other end by a first rear wall portion being folded over and sealed to a front wall. The opening between a second rear wall portion and opposed front wall forms the valve which is sealed after filling by folding the longitudinally extending second rear wall portion over and sealing it to the opposed front wall using the folded first rear wall portion as a reference. Adjacent lateral termination of the plural ply rear wall portions are oppositely stepped so as to overlap when sealed to the front wall.
