ABSTRACT:
Super-miscible blends of nylon copolymers are provided as well as multilayered film structures made therefrom. A nylon composition is a substantially uniform blend of at least one semi-crystalline copolymer I and at least one semi-crystalline copolymer II, wherein the proportion by weight of each of copolymer I and copolymer II. The nylon compositions are extremely uniform, and have only a single melting point rather than individual melting points of the component nylon copolymer parts. Coextruded films of a layer of this nylon composition with an olefin containing polymer are suitable for use as barrier films, such as aroma barrier films, which have reduced curl.
