Title:
PROPYLENE RESIN MULTI-LAYER SHEET, AND PACKAGING BODY FOR HEAT TREATMENT USING SAME
Document Type and Number:
WIPO Patent Application WO/2012/036063
Kind Code:
A1
Abstract:
Provided are a propylene resin multi-layer sheet and a packaging body for heat treatment which have excellent characteristics such as transparency, flexibility, and impact resistance at very low temperatures; reduced thickness fluctuation during laminating; reduced interface roughness and other appearance defects; and improved reduction in thickness during secondary processing. A propylene resin multi-layer sheet having at least two layers comprising an inner layer (1) and an outer layer (2), wherein the inner layer (1) comprises a resin composition containing 40−89 wt% of a specific propylene resin composition (A), 10−40 wt% of a specific ethylene-α-olefin copolymer (B), and 1−20 wt% of a specific propylene resin (C); and the outer layer (2) comprises a specific propylene resin composition.
