Document Type and Number:
Japanese Patent JP3630485
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a polyolefin resin multilayer film being optimum for a push-up type stretch packaging machine in particular, regarding a film used for stretch packaging or the like.
SOLUTION: In regard to a polyolefin resin multilayer film for stretch packaging which is constructed of at least four layers, i.e., two surface layers, an orientation helping layer and a core layer containing crystalline polybutene-1, the 100 & elongation load of the film in the longitudinal direction is made 250-550g/cm in width, while the 100% elongation load thereof in the lateral direction is made 50-200g/cm in width, and the ratio of the 100% elongation loads in the longitudinal direction/the lateral direction and MFR of the crystalline polybutene-1 resin in the core layer are made to be within specific ranges respectively.
