Abstract
Disclosed is a olefin resin composition comprising a propylene resin (PP) and an ethylene resin (PE) at a PP:PE mixing ratio of 97 to 60:3 to 40 by weight, the propylene resin and the ethylene resin having such dynamic melt viscoelasticity that the PE to PP viscosity ratio, i.e., .eta.r=.eta.PE/.eta.PP, is more than or equal to 0.1 and less than 1 at 1 rad/sec and more than or equal to 0.70 at 100 rad/sec and that the difference of modulus of melt elasticity between PP and PE, i.e., .DELTA.G'=GPP-GPE, is 10000 Pa or more; an olefin sheet comprising the olefin resin composition; and an olefin resin laminated sheet having a surface layer and an intermediate layer in which the intermediate layer comprises the olefin resin composition.
