TEAR-RESISTANT LAMINATE STRUCTURE

摘要

A laminate structure including a substrate, a single ply, oriented polyethylene film having a cross-sectional thickness ranging from about 1 to about 4 mils, and a tie layer positioned between the substrate and the polyethylene film, wherein the laminate structure has a machine direction and absorbs at least 1.5 inch-lbforce of energy before failing and stretches at least 15 percent before failing, as measured at any angle relative to the machine direction using the Graves tear test modified with an initial jaw separation of 2 inches.
