To provide a laminated film which has a lower temperature heat seal property, and can safely perform the direct heating cooking in the state a pillow type bag of the film containing fresh vegetables by a microwave oven or the like.
The polyolefin based laminated film for package is produced by laminating a layer (C), a layer (B), and a layer (A) which are layers of the following resins on one surface of a lengthwise and crosswise stretched substrate layer (D) by a crystalline propylene: the layer (C) is a three-base copolymer resin consisting primarily of propylene and consisting of ethylene and a 4C-6C olefine (the olefine is abbreviated to Of); the layer (B) is a blend resin in which low density polyethylene of 15-40 pts.mass is blended into a two-base copolymer resin of ethylene and Of of 100 pts.mass; and the layer (A) is a blend resin of a noncrystalline two-base copolymer resin by propylene and Of of 50-75 mass% and a crystalline two-base copolymer resin of propylene and Of of 50-25 mass%. In addition, a single resin of Of of 5-45 pts.mass is blended into the layer (A).
