Abstract

The multilayer film serves as a laminate. In some embodiments, the film is a multilayered structure that, in its base form, encompasses an intermediate layer with first and second outer layer affixed to opposing sides of the intermediate layer. In some embodiments, the first outer layer is a semi-crystalline fluoropolymer. In some embodiments, the intermediate layer includes a polyester and the second outer layer is an olefinic polymer.
