Beschreibung
Zusammenfassung:	Film and sheet materials, and articles made therefrom, such as bags pouches, trays etc., comprise one or more layers of homogeneous alpha-olefin vinyl aromatic copolymer, preferably an ethylene/styrene copolymer. The alpha-olefin/vinyl aromatic copolymer has properties which can provide a desired performance characteristics such as impact resistance, printability, RF sealability, free shrink, optics, high permeability, etc. The homogeneous alpha-olefin/vinyl aromatic copolymer may be present in a monolayer film, either alone or in a blend, or may be included in one or more layers of a multilayer film. Also included is a multiplayer thermoformable article comprising a web having a film of such alpha-olefin/vinyl aromatic copolymers thereto.
