Abstract

PURPOSE:To provide the titled film containing a crystalline PP component and an ethylene-propylene random copolymer component at a specific ratio, having low content of gel and fish eye and exhibiting excellent freeze-resistance, low-temperature impact resistance and antiblocking property. CONSTITUTION:The objective film is composed of (A) 55-98wt.% of crystalline PP component and (B) 2-45wt.% of an ethylenepropylene random copolymer component. The ratio of [eta]EP/[eta]PP of the film is 0.5-2.0 wherein [eta]PP and [eta]EP are intrinsic viscosity values of the components A and B, respectively. The polymer composition is produced preferably by using a prescribed mixture of the above components as a raw material monomer and carrying out two-stage polymerization of the monomer using a stereoregular catalyst.
