<p>The invention provides a multilayered thermoplastic film which may be utilized to form storm windows or packaging material. The film comprises a core layer consisting essentially of either (a) a copolymer of ethylene and vinyl acetate or (b) a three component blend of (a) a linear low density polyethylene, (b) a linear medium density polyethylene and (c) an ethylene vinyl acetate copolymer. The film also comprises two intermediate layers each consisting essentially of a linear low density polyethylene, and two surface layers each consisting essentially of either of a four component blend of (1) a linear low density polyethylene, (2) a linear medium density polyethylene, (3) a copolymer of ethylene and vinyl acetate and (4) one or more light stabliizers, or a three component blend in which light stabilizers are not present.</p> |
