LAMINATED SEAMLESS CAN

摘要

PROBLEM TO BE SOLVED: To provide high-quality film coated steel two-piece cans with high productivity. SOLUTION: The laminated seamless can obtained by subjecting a laminated steel sheet having chemical conversion treatment films mainly composed of an organic resin of 20 to 2,000 mg/m2 as the coating build-up per side on both surfaces of a steel sheet and 1 to 100 mg/m2 as the weight of C on the upper layers thereof and having polyester resin film on the upper layer thereof to drawing-ironing. The film on the inside surface side of the can is the two-layered films of (A) a thickness 10 to 45μm, a melting point 215 to 245 deg.C and cold crystallization heat 8.5 to 35.0 j/g and (B) a thickness 5 to 20μm and a melting point 235 to 260 deg.C. The can is coated with the film (A) so as to come into contact with the steel sheet and the entire part of the film is made amorphous.
