FLUID CONTAINER POUCH

摘要

A fluid container pouch has first and second opposing side walls forming at least one enclosed chamber between them, each side wall is comprised of a laminate material having at least two layers. A first layer of the laminate is sealant layer for sealing to a sealant layer of an opposed side wall. A second layer of the laminate provides a barrier between the contents of the pouch and its environment. Each of the first and second layers comprises a material having oriented structure, such that energy sufficient to tear the material will be directed in a predetermined direction across the material, and further that the oriented structures of the first and second layers are aligned with each other. At least one design weakness in the pouch operative to direct tearing energy in a direction aligned with the oriented structure of said first and second layers.
