Abstract
The present invention provides a wrap film or shrink film formed from a resin composition containing [I] a propylene polymer in an amount of 1 to 99 mass %, and [II] an olefin-based polymer in an amount of 99 to 1 mass %, wherein [I] the propylene polymer satisfies the following requirements of: (1) a meso pentad fraction (mmmm) is 0.2 to 0.6, and (2) a racemic pentad fraction (rrrr) and (1−mmmm) satisfy the following relation: [rrrr/(1−mmmm)]≦0.1. The wrap film or shrink film exhibits excellent characteristics, and does not generate a toxic gas derived from chlorine, such as hydrogen chloride gas or dioxin, when being incinerated.

A wrap film formed from a resin composition comprising [I] a propylene polymer in an amount of 1 to 99 mass %, and [II] an olefin-based polymer in an amount of 99 to 1 mass %, wherein [I] the propylene polymer satisfies the following requirements of:
- (1) a meso pentad fraction (mmmm) is 0.2 to 0.6, and
- (2) a racemic pentad fraction (rrrr) and (1−mmmm) satisfy the following relation:
- [rrrr/(1−mmmm)]≦0.1
A stretched shrink film formed from a resin composition comprising [I] a propylene polymer in an amount of 1 to 99 mass %, and [II] an olefin-based polymer in an amount of 99 to 1 mass %, wherein [I] the propylene polymer satisfies the following requirements of:
- (1) a meso pentad fraction (mmmm) is 0.2 to 0.6, and
- (2) a racemic pentad fraction (rrrr) and (1−mmmm) satisfy the following relation:
