Abstract
Multilayer films comprising three or more layers have improved properties for a variety of applications. The multilayer films often have a total thickness of from about 10 to about 50 microns. Blown multilayer film properties may include excellent cling with reduced unwinding noise levels. Cast multilayer film properties include improved elasticity, impact, puncture, and tear properties.
