Title:
LAMINATED BODY, PACKAGING BODY, AND METHOD FOR PRODUCING LAMINATED BODY
Document Type and Number:
WIPO Patent Application WO/2023/176468
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a laminated body which includes a polyolefin resin substrate, is dense, and has good barrier properties; a packaging body; and a method for producing the laminated body. The solution to this problem is a laminated body comprising a polyolefin resin film, a metal layer and/or an inorganic compound layer, and a coating layer being disposed in this order on at least one surface of the polyolefin resin film. The ratio P1/P2 between peak intensities P1 and P2 is 3.5-8.0, the peak intensities being determined by measurement with a FT-IR-ATR method. P1 is the intensity of the greatest peak present in the 1,050 to 1,080 cm-1 range; and P2 is the intensity of the greatest peak present in the 920 to 970 cm-1 range.
