Document Type and Number:
WIPO Patent Application WO/2023/145760
Kind Code:
A1
Abstract:
The present invention pertains to a non-oriented film, a laminate, and packaging. The non-oriented film has a base material layer and a sealant layer formed from a resin composition comprising, at prescribed ratios, a propylene polymer (A), a 1-butene/α-olefin copolymer (B), and a propylene/α-olefin copolymer (C). The propylene polymer (A) has a melting point (Tm) of 120-170°C, inclusive, as measured using differential scanning calorimetry (DSC). The copolymer (B) has a melting point of less than 120°C as measured using DSC, and contains 51-99 mol% constituent units derived from 1-butene and 1-49 mol% constituent units derived from an α-olefin. The copolymer (C) has a melting point of less than 120°C as measured using DSC, and contains 51-95 mol% constituent units derived from propylene and 5-49 mol% constituent units derived from an α-olefin.
