Serious problems arise in the rapid detinning of plain tinplate cans, particularly when the cans contain are tropical fruit with high nitrate concentrations poses.An investigation found that rapid detinning does not occur in presence of high nitrate concentrations, because the tin sulfide film formed on the tinplate surface surpresses detinning.We confirmed that sulfur forming tin sulfide originates from cans contents, i.e. sulfur-containing compounds that determine fruit flavor and taste. Sulfur-containing compounds such as L-cysteine are particularly thermally unstable and decomposed by heat treatment. Tin sulfide film surpresses detinning, and tends to cause iron dissolution reaction, meaning that due care must be exercised.

Lightly tin coated steel (LTS) is widely used for the welded can, the filiform corrosion is the important performance of LTS.The tin coating weight and reflow treatment to improve the filiform corrosion resistance has been studied, and the following facts are revealedThe filiform corrosion is greatly improved by the increase of the tin coating weight and the reflow treatment. These factors increase the cathodic polarization, so that the reaction of oxygen reduction is restrained. This is considered to be the reason why the process of filiform corrosion is impeded.
