The closed end includes an end gusset wherein there are two lateral edge heat seals. The lateral edge heat seals are formed by a four-fold gusset. The outer surface of one of the folds can be provided with a metallic surface whereas the outer surface of a mating fold in the gusset possesses a non-metallic surface. As a result of the present invention, a metallized end-fold gusset can be provided with a capability of heat sealing the lateral edges in the metallized area.
