LAMINATED METAL SHEET FOR CAN LID AND CAN LID MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a laminated metal sheet for a can lid excellent not only in general processability such as score processing or the like but also in processability in local bending processing performed after heat treatment. SOLUTION: The laminated metal sheet for the can lid has an organic resin layer formed by superposing a main layer comprising a polyester resin and a sub-layer comprising a resin with a glass transition point (Tg) of 5°C or below one upon another in a laminar state directly or through an adhesive layer. Since the organic resin layer is formed by superposing the main layer comprising the resin satisfying general processability such as rivet processing or score processing and the sub-layer comprising a resin excellent in local bending processability one upon another, excellent local bending processability is obtained almost without damaging general processability when the organic resin layer is adapted to an easy open end type can lid material.
