Document Type and Number:
Japanese Patent JP3781596
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a polyolefin laminated film which shows heat sealing properties and also outstanding tear directional property in a transverse direction and suitability to packaging machine.
SOLUTION: This film is composed of a biaxially stretched layer A and a monoaxially stretched layer B laminated on one of the faces of the former and a heat sealable layer C laminated on the other non-laminated face of the layer B. In addition, the film is characterized in that the melt point(ATm) of a resin making up the layer A is the same as the melt point(BTm) of a resin making up the layer B or the melt point(ATm) of the resin making up the layer A is higher within a range of 15°C or less than the melt point(BTm) of the resin making up the layer B. Further, the thickness of the layer A accounts for 65-95% of the entire thickness of the polyolefin laminated film.
