    摘要: The polyolefin composite film is excellent in low-temperature heat sealability, heat-sealing strength and transparency, and at least has surface layer [i]//intermediate layer [iii]//core layer [ii], wherein the surface layer [i] includes a propylene resin composition including 0-50 wt % of a specific propylene/α-olefin random copolymer (A) and/or a specific 1-butene/α-olefin copolymer (E), and 50-100 wt % of a propylene polymer (B) having a melting point of 120-170° C. ((A), (E) and (B) in the surface layer totals 100 wt %); the core layer [ii] includes a propylene resin composition including 70-100 wt % of a crystalline polypropylene (C) having a melting point of 150-170° C., and 0-30 wt % of the copolymer (A) ((C) and (A) in the core layer totals 100 wt %); and the intermediate layer [iii] includes a propylene resin composition including 50-95 wt% of the crystalline polypropylene (C) and 50-5% of the polymer (B), the copolymer (A), and/or the copolymer (E) ((C), (B), (A) and (E) in the intermediate layer totals 100 wt %).

    摘要: Propylene-based polymers (A) are provided which, when used as pressure-sensitive adhesives to various adherends, show a desired initial adhesion and will not contaminate the adherends and which have excellent pellet handling properties. Pellets of the invention contain the propylene-based polymers (A). Pressure-sensitive adhesives of the invention contain the propylene-based polymers (A). The propylene-based polymer (A) includes 65 to 80 mol % of a structural unit derived from propylene, 5 to 10 mol % of a structural unit derived from ethylene and 15 to 25 mol % of a structural unit derived from a C4-20 α-olefin (wherein these percentages are calculated based on 100 mol % of the total of the structural unit derived from propylene, the structural unit derived from ethylene and the structural unit derived from a C4-20 α-olefin) and has a heat of crystal fusion of 5 to 45 (J/g) as measured by DSC. Compositions of the invention contain the propylene-based polymers (A).
