Title: LAMINATE, METHOD FOR MANUFACTURING SAME, AND SEALANT FILM
Abstract:
The purpose of the present invention is to provide a laminate having high adhesive strength between a polyethylene layer and a substrate layer, without using an anchor coat agent. Provided is a method for manufacturing a laminate, including a step of extrusion laminating a substrate and a resin composition including an ethylene-based polymer and an ethylene-based polymer composition containing a phosphorus-containing compound having a specific structure, so that the resin composition and the substrate are in direct contact, wherein the method is characterized in that the ethylene-based polymer contains at least one of a high pressure low density polyethylene and a copolymer of ethylene, and an α-olefin having 3 to 10 carbon atoms, and the ethylene-based polymer composition satisfies predetermined conditions.
