Abstract: A process to increase resistance to tearing in a heat-resettable material involves extruding a polymer of a specified crosslinking density to produce a plastic web. After cooling the plastic web is heated by creating a temperature decreasing towards its core and stretched at core temperature below crystalline melting temperature of partially crystalline and crystalline polymers resulting in a distribution of orientation over the full section of the plastic web. Resistance to tearing will be essentially increased in this manner based on a simple, low-cost production process.

Abstract: An exemplary method for measuring the impact resistance of polymeric film-based laminates involves a falling dart test using laminates that are essentially fully adhered to an inclined mortar block in emulation of stone impacts in backfill situations.
