Title:
FILM, METHOD FOR PRODUCING FILM, AND PROPYLENE-BASED POLYMER COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2022/209190
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a film which has a relatively high tensile modulus of elasticity (Young's modulus) in both the MD direction and the TD direction, has a relatively low thermal shrinkage rate in the TD direction, and has relatively excellent uniform stretchability in the TD direction during production.　The film contains a propylene-based polymer or a propylene-based polymer composition, and satisfies formula (I) or the like. 0.35
