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 mum to 1.8 mum: r1, 0.1r1/Rh/(R-r) wherein h is the height of the two-piece can body, r is the maximum radius, r1 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.
