摘要
A method of making the a multilayer, biaxially oriented, heat shrinkable thermoplastic film includes a layer having between 50 and 100 parts by weight ethylene/alpha-olefin C4-C12 copolymer, and between 0 and 50 parts by weight of a polymer selected from polyolefin, and modified polyolefin, the layer having more than one melting point when detected by diffential scanning calorimetry according to ASTM D-3418; wherein the total thickness variation in the multilayer film is lower than ±10%.
