The corrosion resistance of easy open end canned food

Orange, pineapple and other easy open end canned food, use plain iron, in order to keep the food in the jar pop flavor and color. These foods are acidic, required to cover can have high corrosion resistance. The main factors related with corrosion can have used tin plate materials, content types, canning conditions, storage conditions etc..

From the tin plate material, in the oxygen free acidic environment, tin was first dissolved by corrosion and protected the iron. In order to improve the corrosion resistance of tinplate, strict production control is required, with high corrosion resistance plate.

In order to reduce the cost and save precious tin resources, people no longer use increased tin layer to improve the corrosion resistance of the way, but with low tin coating paint to improve EOE canned life; paint can prevent sulfur protein food to drink, sulfide blackening; beer flavor is very sensitive to a small amount of dissolved metals, the use of paint cans. But the film flawed EOE canned shelf-life than painting is much shorter, so to prevent the film scratches, flinging parts damage, or cover film produced in the stamping of off. In order to ensure the quality of the film, sometimes several times for painting; strong acidic drinks in cans must be carried out after spraying, to prevent corrosion soon, even leakage.
