Abstract

A multi-layered nanocomposite film for use in packaging is provided. More particularly, the film contains at least one core layer positioned adjacent to at least one outer layer. For example, in one embodiment, the film contains a core layer that is positioned between two outer layers. The core layer(s) and/or outer layer(s) may be formed from a polymer composition that contains an ethylene polymer, nanoclay having an organic surface treatment, and a compatibilizer that includes an olefin component and a polar component.
