LAMINATED METAL PLATE FOR TWO-PIECE CANS AND TWO-PIECE LAMINATED CAN BODY

摘要

This laminated metal plate comprises: a metal plate; a first polyester resin layer that is formed on a surface of the metal plate, said surface forming the outer surface of a container; and a second polyester resin layer that is formed on another surface of the metal plate, said another surface forming the inner surface of the container. The first polyester resin layer contains: from 30% by mass to 60% by mass (inclusive) of a polyethylene terephthalate or a copolymerized polyethylene terephthalate that has a copolymer content of less than 6% by mole; from 40% by mass to 70% by mass (inclusive) of a polybutylene terephthalate or a copolymerized polybutylene terephthalate that has a copolymer content of less than 5% by mole; and from 0.01% to 3.0% (inclusive) of a polyolefin wax relative to the total amount of the other components. The second polyester resin layer is formed of a copolymerized polyethylene terephthalate that has a copolymer content of less than 22% by mole. The first and second polyester resin layers have a residual orientation degree of less than 30%.
