ABSTRACT:
Film and sheet materials, and articles made therefrom, such as bags, pouches, trays, etc., comprise one or more layers of a thermoplastic, homogeneous alpha-olefin/vinyl aromatic copolymer, preferably an ethylene/styrene copolymer. The alpha-olefin/vinyl aromatic copolymer has properties which can can provide a desired performance characteristics such as impact resistance, printability, RF sealability, free shrink, optics, as well as many others. 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 multilayer thermoformable article comprising a web having a film of such alpha-olefin/vinyl aromatic copolymers therto. Finally, also included is an RF-sealable film comprising such copolymers.
