Document Type and Number:
WIPO Patent Application WO/2023/243691
Kind Code:
A1
Abstract:
Provided is a polyethylene laminate that is highly recyclable, has excellent physical properties such as rigidity, strength, and impact resistance, and is excellent in heat sealability and transparency. A stretched polyethylene film for lamination composed of a polyethylene composition (X) that is (i) or (ii) below. (i) Polyethylene composition (X) containing 90-99.5 wt% of a polyethylene (A) having a weight average molecular weight (Mw) measured by gel permeation chromatography of 90,000-250,000 and a density measured by JIS K6922-1 (1997) of 945-980 kg/m3 and 0.5-10 wt% of a propylene polymer (B) having a lower viscosity than the polyethylene (A) or a cyclic olefin polymer (C). (ii) Polyethylene composition (X) containing 95-99.9 wt% of the polyethylene (A) and 0.1-5 wt% of a nucleating agent (D).
