LAMINATED STEEL SHEET FOR TWO-PIECE CAN BODY, METHOD FOR MAKING TWO-PIECE CAN BODY, AND TWO-PIECE CAN BODY MADE OF LAMINATED STEEL SHEET

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: r1 <= r, 0.1 <= r1/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, 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.
