Abstract: A multilayer film has a first outer layer, an inner layer, and a second outer layer. The first outer layer comprises a homogeneous ethylene/alpha-olefin copolymer. The inner layer comprises a thermoplastic elastomer. The second outer layer comprises a second ethylene/alpha-olefin copolymer. The inner layer is between the first outer layer and the second outer layer, and is chemically different from the first outer layer and the second outer layer. The multilayer film has an O.sub.2 -transmission rate of from about 500 to 50,000 cc/m.sup.2 24hr STP, and a modulus of at least 60,000 psi. The multilayer film is especially useful for the packaging of O.sub.2 -sensitive products, such as produce. The high modulus of the film enhances its performance in form-fill-and-seal operations.

Abstract: A film includes a layer derived from PVDC-containing composition having properties such as good thermal stability, enhanced extrudability, improved oxygen barrier properties, and reduced stickiness to metal surfaces. The composition includes a three components: a vinylidene chloride-containing polymer, a processing aid polymer, and a material useful for preventing the degradation of PVDC.
