摘要：
A multilayer film is herein provided. The film, which is useful for packaging, comprises: - a core barrier layer having an outer side and an inner side, said core barrier layer comprising one or more barrier polymers that exhibit moisture and/or oxygen barrier properties, wherein said barrier polymer is optionally coupled to a slow crystallizing polyamide or a polymer blend thereof; - an outer layer bonded to the outer side of the core barrier layer comprising a rigid polymer having an inherent viscosity (IV) in the range of about 3.2 to 4.7, wherein the outer layer optionally comprises slow crystallizing polymer (SCP) or a polymer blend thereof; and - a sealant layer bonded to the inner side of the core barrier layer comprising one or more polyolefins sufficient to provide a seal.
