发明名称 MULTI-LAYER POLYOLEFIN FILM AND PACKAGE
摘要 PROBLEM TO BE SOLVED: To provide a multi-layer polyolefin film which is excellent in low temperature heat-seal properties during packaging and in easy openability of a heat seal part and suitable for packaging, and a multi-layer polyolefin film which is excellent in low temperature heat fusion properties and easy openability without causing the lowering of fusion strength of the melt cutting seal part and gazette seal part of a bag for twist packaging. SOLUTION: The multi-layer polyolefin film excellent in low temperature heat-fusion properties and easy openability is composed of a heat fusion layer which can be obtained from 20-80 wt.% of a propylene.α-olefin random copolymer (A) 120-150 deg.C in melting point and 80-20 wt.% of a composition comprising polybutene (B) containing 5-50 wt.% of linear low density polyethylene (D), and the linear low density polyethylene (D); and a polypropylene (C) layer. In a multi-layer polyolefin film package, the contents of the multi-layer film are enclosed, and the upper or lower part of the twist part of the package is heat-fused.
