Abstract

A continuous chain of multilayered flexible container pouches is produced by combining two continuous strips of thermoplastic film to form the walls of an inner bag, sandwiching them between another two continuous strips of thermoplastic film to form an encasing outer bag, and heat welding inner and outer film layers longitudinally and transversely. The bags can also be produced using longitudinally folded film strips so that only one pair of longitudinal edges require sealing or tubular film can be used, the outer tube being extruded about the inner. - A spout zone is provided on one edge of each bag where the outer bag is not welded to the inner. Pref. the spout zone is formed in conjunction with an overlapping welded portion containing a cut-out to facilitate carrying. Pref. the transverse seals are spaced apart to provide a web portion which can be perforated or severed during mfr. - The pouches can be used for packaging milk and wine but more partic. are intended for liquids which must be packaged under stringently sterile conditions. The inner bag remains in a sealed condition until the moment of filling when it is punctured in the spout zone. After filling, the puncture is resealed by heat welding.
