Abstract
The multilayer film serves as a laminate. 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. The first outer layer is a semi-crystalline fluoropolymer. The intermediate layer includes a polyester and the second outer layer is an olefinic polymer. The layers are bonded together in the noted order to provide the multilayer film.
Claims13
A multilayer film comprising:
- a first outer layer of a semi-crystalline fluoropolymer with a tensile modulus of less than 100,000 psi;
- an intermediate layer of a polyester having at least two planar directions and a first and second surface, wherein the intermediate layer has a shrinkage of less than about 1% in each planar direction when held for 15 minutes at 150° C. measured in accordance with ASTM 2305-02;
- and
- a second outer layer of an olefinic polymer, wherein the first outer layer and the second outer layer are bonded to opposing sides of the intermediate layer.
