摘要： A multilayer film is disclosed in which at least one layer thereof comprises a blend of: a first styrene butadiene copolymer having a butadiene content of 50 weight percent or more; and a second styrene butadiene copolymer having a butadiene content of 50 weight percent or less, wherein, the total butadiene content of the blend ranges from about 30 weight percent to about 50 weight percent. When used as an outer layer of an overwrap material, such blend provides an improved overlap heat seal.
