ABSTRACT:
A process of manufacturing webs of side connected bags is disclosed. A tube of heat sealable material is flattened and spaced, transverse seals are formed from one edge of the tube toward the other to delineate bag sides. Thereafter, the seals are bisected by lines of weakness to facilitate separation of sides of adjacent bags. Longitudinal lines of weakness are formed immediately adjacent the seals to delineate the tops of bag faces and backs and a separate top or lip section.
