Resin-coated seamless can

摘要

A resin-coated seamless can satisfying such properties as high degree of workability, adhesiveness of film, resistance against high temperatures and wet heated condition, corrosion resistance and resistance against being dented. The resin-coated seamless can is formed of a resin-coated metal plate having substantially unoriented two layers including a surface layer and a lower layer serving as a resin layer on the inner surface side of the can, wherein the surface layer comprises a polyethylene terephthalate/isophthalate containing an isophthalic acid in an amount of from 3 to 13 mol % and having an intrinsic viscosity [eta] of not smaller than 0.7, and the lower layer comprises a polyethylene terephthalate/isophthalate containing the isophthalic acid in an amount of from 8 to 25 mol %, which is larger than that of the surface layer, and having an intrinsic viscosity [eta] of not smaller than 0.7, the resin layer of the upper part of the can on the inner surface side satisfying the following formula (1), Cs>Ca (1) where Cs=Is973/Is795, Ca=Ia973/Ia795, Is973 is an infrared absorption intensity at 973 cm-1 measured for the surface layer, Is795 is an infrared absorption intensity at 795 cm-1 measured for the surface layer, Ia973 is an infrared absorption intensity at 973 cm-1 measured for the lower layer and Ia795 is an infrared absorption intensity at 795 cm-1 measured for the lower layer, and, preferably, the coefficient of surface orientation of the resin layer on the inner surface side on the bottom of the can being not larger than 0.05.
