摘要： A laminated resin film having a thickness of from 7 to 25 .mu.m comprised of (A) a poly(4-methylpentene-1) resin layer having a thickness of from 1 to 10 .mu.m having laminated on one or both sides thereof (B) a crystalline propylene copolymer resin layer comprising from 1 to 10% by weight of ethylene, from 74 to 96% by weight of propylene, and from 3 to 25% by weight of an .alpha.-olefin containing from 4 to 8 carbon atoms and having a thickness of from 2 to 20 .mu.m, provided that the total thickness of layers (B) when provided on each side of layer (A) is in the range of from 4 to 20 .mu.m. The laminated film has excellent cutting properties and high heat resistance sufficient for use in microwave cooking.
