Abstract:
This invention relates to an anisotropic multilayer film and the process of making a multilayer film, wherein a supercritical blowing agent is introduced to at least one layer, wherein at least one layer comprises 10 to 100 percent by weight LLDPE with a melt index of 0.2 to 2 g/10 min. The film in this invention can have a surface with an average Sheffield smoothness, according to TAPPI T 538, of less than 100. The film in this invention can have a puncture propagation tear resistance, in accordance with ASTM D2582, greater than 500 g/mil.
