Polyethylene films having high resistance to deformation or elongation

摘要

Disclosed is a method for producing polyethylene films which have high resistance to deformation or elongation under loading in tension. The method comprises orienting in the machine direction (MD) a high density polyethylene film at a draw-down ratio effective to give the film an MD tensile strength at yield greater than or equal to 50,000 psi, wherein the HDPE has a density greater than 0.940 g/cm3.
