A thermoplastic multilayer film having improved processability and sealability comprises: a) a core layer comprising a polyolefin selected from the group consisting of isotactic PP homopolymer, EP copolymer, HDPE, and LLDPE; b) a first transition layer external to the core layer wherein the first transition layer comprises a polyolefin selected from the group consisting of syndiotactic PP, EP copolymer, PB copolymer, EPB terpolymer, MDPE, LLDPE, LDPE, metallocene-catalyzed PE, EVA copolymer, EMA copolymer, and ionomer; and c) a first skin layer external to the first transition layer and the core layer wherein the first skin layer comprises a polyolefin selected from the group consisting of PP homopolymer, HDPE, EP copolymer, PB copolymer, EPB terpolymer, MDPE, and LLDPE, the first skin layer being at least 0.5 micron in thickness with a melting point at least 5° C. greater than the first transition layer. |
