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.

Tear-resistant laminate structure

A thermo-mechanically stable, heat sealable mono-axially oriented polymer substrate film includes polymers based on low density polyethylene. The thermo-mechanically stable, heat sealable mono-axially oriented polymer substrate film can consist essentially of the polymers based on low density polyethylene. The disclosure also describes a vapour deposition coated substrate film, especially such a film which is metallised, a packaging laminate comprising the vapour deposition coated polymer substrate film, and a packaging container produced from such a packaging laminate. Also disclosed is a method for the production of the thermo-mechanically stable, heat sealable polymer substrate film and a method of vapour deposition coating the film.
