摘要

Disclosed is a side seam-coated welded can comprising a welded can body having a seam on the side face and a resin coating layer covering at least one surface side of the seam, wherein said coating layer comprises a thermosetting resin and a thermoplastic resin having a softening point of 50 DEG to 300 DEG C. as determined according to the ring and ball method, at a volume ratio ranging (A) from 95/5 to 25/75 or (B) from 20/80 to 1/99, and one of said two resins is present in the coating in the form of a continuous phase and at least a part of the other resin is present in the coating in the form of fine dispersed particles. This can is excellent in corrosion resistance and processability.
