    摘要: Compositions are provided comprising a propylene-ethylene copolymer containing about 1 to about 7 weight percent ethylene and an ethylene-alkyl acrylate copolymer containing at least about 20 weight percent ethylene, wherein the composition contains about 10 to about 25 weight percent alkyl acrylate, based on the combined weight of propylene-ethylene copolymer and ethylene-alkyl acrylate copolymer. Films made from these compositions have good RF sealing properties, as well as good flexibility at low temperatures.
