LAMINATE STEEL SHEET FOR CAN BODY OF TWO-PIECE CAN AND TWO-PIECE CAN COMPRISING LAMINATE STEEL SHEET |
摘要 |
A laminated steel sheet for use in the manufacture of a two-piece can body that satisfies the following three formulae includes a polyester resin layer on at least one side of the steel sheet, the polyester resin layer containing 3% to 30% by volume of dispersed incompatible subphase resin having a glass transition point of 5°C or less and a cross section aspect ratio of 0.5 or less:
wherein R denotes the radius of a circular laminated steel sheet that has the same weight as that of the two-piece can body before processing, h denotes the height of the can body, r denotes the maximum radius of the can body, and d denotes the minimum radius of the can body. A high strain two-piece can, such as a two-piece aerosol can, formed of the laminated steel sheet is free from delamination and breakage of the resin layer. |
