Abstract:
A propylene based resin composition comprising:(i) about 70 to 90% by weight of a propylene block copolymer; and(ii) about 30 to 10% by weight of an ethylene based resin, wherein:(a) the relation between its die swelling ratio (SR.sub.1) at a shear rate of 6.08 sec.sup.-1 and its die swelling ratio (SR.sub.2) at a shear rate of 608 sec.sup.-1 satisfies the following formula (1); and(b) the relation among its Izod impact value (kJ/m.sup.2) at a temperature of 0.degree. C., its flexural modulus (MPa) at a temperature of 23.degree. C. and its haze value (%) satisfies the following formula (2)SR.sub.2 /SR.sub.1.ltoreq.about 1.10 (1)Izod impact value.times.Flexural modulus/Haze value.gtoreq.about 200 (2).
