Patent

CA 2199541

A plastic packaging material which, when formed as a package having seams, will provide a predictable line of failure along a seam when the package is opened to prevent the package from tearing down the side. The predictable failure path is provided through a lamination process involving specific resins or blends of resins laminated in three (or more) layers in which an extruded inner layer forms a weak inner bond wholly within that inner layer to create the predictable line of failure and in which the process of forming the material does not inhibit processing speed, efficiency, and economics of materials used to provide this reliable openability.
