EASILY-OPENABLE LAMINATED FILM, EASILY-OPENABLE LID MATERIAL AND EASILY-OPENABLE CONTAINER USING THE SAME, AND FOOD PACKAGE MATERIAL FOR EXTRUSION LAMINATION USED FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an easily-openable laminated film which is excellent in high-speed moldability in extrusion laminate molding, is comparatively simple and can be inexpensively produced, has a sufficient seal strength and proper easy openability, and can obtain excellent peeling appearance.;SOLUTION: An extrusion lamination film of a thermoplastic resin composition has a lamination structure which has at least a support and a seal layer provided on one surface side of the support in this order, where the seal layer contains at least the following components (A) to (C), and the seal layer contains, with respect to 100 pts.mass of the total of the component (A), the component (B) and the component (C), 15-45 pts.mass of the component (A), 25-40 pts.mass of the component (B), and 25-45 pts.mass of the component (C). Component (A): a thermoplastic styrenic elastomer formed from a cross copolymer. Component (B): a polystyrene-based resin. Component (C): a polyethylene-based resin.;SELECTED DRAWING: None;COPYRIGHT: (C)2019,JPO&INPIT
