LAMINATE STEEL SHEET FOR TWO-PIECE CAN, METHOD FOR PRODUCTION OF TWO-PIECE CAN, AND TWO-PIECE LAMINATE CAN

摘要

A laminated steel sheet for a two-piece can body with a high strain level satisfying the following formulae, the polyester resin layer composing the laminated steel sheet having a center line surface roughness (Ra) of 0.2 µm to 1.8 µm: r 1 ‰¤ r , 0.1 ‰¤ r 1 / R ‰¤ 0.25 , and 1.5 ‰¤ h / R - r ‰¤ 4 wherein h is the height of the two-piece can body, r is the maximum radius, r 1 is the minimum radius, and R is the radius of the circular laminated steel sheet before forming having the same weight as the can body.
