Films of Higher Impact Resistance and improved resistance to catastrophic Failure at a degree of deformation

摘要

Stressed that the Films show good resistance to perforations and impacts and to show good resistance to the Propagation of defects. The Films have a maximum pressure of at least 200 percent, a catastofica tensile force of at least 95% of the heat Breaking elongation (cf. 5 or less).The Films preferably comprise at least 3 layers and preferably contain at least 50 percent by weight of the polyethylene Polymers.
