Abstract
Multilayer cast films with an ethylene/α-olefin copolymer core layer, and inner and outer layers containing low density polyethylene homopolymers, and multilayer cast films with an ethylene polymer core layer, and inner and outer layers containing ethylene/α-olefin copolymers, are described. These cast films have a reduced tendency to block, and are useful in various food packaging applications.
