THREE LAYER FILM HAVING A CORE LAYER OF LOW PRESSURE LOW, DENSITY POLYETHYLENE

摘要

A flexible co-extruded three layer film comprises outer layers of high pressure, low density polyethylene and a core layer of low pressure, low density polyethylene. The film is produced by conventional methods at conventional rates and yet is free of melt fracture even though the low pressure, low density polyethylene would otherwise exhibit melt fracture.
