PURPOSE:To enlarge a draw ratio range by specifying a first and a second components to be placed in side by side type or eccentric type. CONSTITUTION:A composition comprising polypropylene (<5 Q value and <=15-<200 melt flow rate at 190-300 deg.C) as a first component 1 and 60-100wt.% ethylene-propylene random copolymer (<=137 deg.C-<145 deg.C melt peak temperature), 0-40wt.% ethylene-butene-propylene terpolymer (<=133 deg.C-<145 deg.C melt peak temperature) and 0-20wt.% polypropylene as a second component 2 is arranged in a side by side type or eccentric sheath core type. The blending ratio of the first component/the second component is (60/40)-(30/70). |
