Document Type and Number:
WIPO Patent Application WO/2019/131168
Kind Code:
A1
Abstract:
A multilayer film which comprises superposed layers including a surface layer (A), an interlayer (B), and a sealing layer (C), wherein the surface layer (A), interlayer (B), and sealing layer (C) each comprise a propylene-based resin and the interlayer (B) includes plant-derived biomass polyethylene (b1), the biomass polyethylene (b1) having a melt flow rate of 1.5 g/10 min or higher. The multilayer film, although including a plant-derived resin ingredient, renders not only suitable sealing strength and impact resistance but also satisfactory fusion-sealing strength in a wide temperature range possible.
