Beschichtete Metallplatte für Dosen und daraus hergestellte falznactlose Dozen

摘要

A polyester laminated draw-formed can which suppresses frothing phenomenon when a carbonated beverage is contained therein and exhibits excellent corrosion resistance, and a coated metal plate used for the production of the cans. The coated metal plate for cans comprises a laminated material of a metal plate, a polyester film layer consisting chiefly of ethylene terephthalate units and, as required, an adhesive primer layer interposed between the metal plate and the polyester film, wherein the polyester film layer that is on the inner surface side of the can has a surface that is molecularly oriented in at least the biaxial directions, and larger protrusions on the surface over a visual field of 100 mu m x 100 mu m as observed using an interatomic force microscope (AFM) have an average height (H) of three points of 0.20 mu m or smaller.
