Title:
延伸フィルム及び微多孔フィルム
Document Type and Number:
Japanese Patent JP7427955
Kind Code:
B2
Abstract:
To provide a film excellent in film formability and thermal shrinkage resistance, to provide a stretched film and to provide a microporous film.SOLUTION: The film is formed of a silane crosslinked body produced by subjecting a modified ethylene/α-olefin copolymer composition prepared by graft-modifying a composition including a propylene-based polymer and an ethylene/α-olefin copolymer (provided that the α-olefin excludes propylene) with an unsaturated silane compound to crosslinking reaction in the presence of a crosslinking catalyst in which the modified ethylene/α-olefin copolymer composition satisfies (1) and (2) as given below: (1) the gel fraction is 65 mass% or more and (2) the melt flow rate (MFR) at 190°C, 2.16 kg is 0.05 g/10 min to 2 g/10 min. The stretched film is produced by stretching the film. The microporous film uses the stretched film.SELECTED DRAWING: None
