Abstract
Disclosed are an easy-cleavage shrink laminate film which is harmless to the environment, easy to tear and moderately shrinkable, and a bag made of the laminate film. The easy-cleavage shrink laminate film,has a basic, two-layered structure composed of an easy-cleavage shrink film,and a sealant film,and may optionally comprise an additional sealant film,and/or a substrate film,to have a multi-layered structure. The easy-cleavage shrink film,comprises from 40 to 85 parts by weight of Ny 6 and from 15 to 60 parts by weight of MXD 6, and this is drawn at an orientation ratio of not smaller than 2.8 times both in the MD direction and in the TD direction and thermally fixed at a heat-treating temperature falling between 120 and 195° C. to thereby have a degree of shrinkage of from 15 to 40% when it is put in hot water at 120° C. under pressure of about 2.0 kg/cm,for 20 minutes.
