Abstract
The present invention provides a surface-treating agent for a metal can, which has an effect of elevating smoothness of the metal can, shows a low foaming property and high thermal stability, but not uneasiness at safety, and thereby contributes to elevate a transferring speed of a metal can body in producing the metal can. A surface-treating agent for a metal can, comprising an emulsion containing a sorbitan fatty acid ester in a concentration of 100 to 2000 mg/l in a water medium, is sprayed to a metal can body in the final stage of a rinsing process which is carried out after a converting process.
