Abstract
A liquid product carrying plastic film pouch having a straw which is free-floating in the liquid product, is described. The liquid product contained within the inner chamber of the pouch occupies from about 60% to about 90% of the volume of the inner chamber sufficient to permit the side walls of the pouch to be collapsed against one another when the pouch is grasped by the hand of a user person whereby to orient the straw at a desired location. The pouch is made of a multilayer resin film having an inner sealant layer formed of a linear low density ethylene-octene copolymer or very low density ethylene copolymer (octene or other copolymers) such that when the straw punctures the film, the inner sealant layer forms a membrane about the straw which exhibits a self-sealing behavior so as to prevent leakage in the punctured region as liquid is extracted from the pouch through the straw.
