Autoclavable, non-adherent, heat sealable polymer films for fabricating monolayer and multiple layered films and containers

The present invention provides polymer blends having a first component of a polymeric material capable of being cross-linked and selected from the group consisting of an ethylene containing polymer, the first component present in an amount by weight of the blend from about (50 %) to about (95 %), the first component having a first melting point temperature determined by DSC; and a second component of a non-readily cross-linkable polymeric material and selected from the group consisting of propylene containing polymers and methyl pentene containing polymers, the second component being present in an amount by weight of the blend from about (50%) to about (5 %), the second component having a second melting point temperature determined by DSC; and a portion of the first component being crossed-linked and the second component is essentially free of cross-linking.
