Product Description
Tinplate coil is available in food grade and non-food grade. The main grades are MR and SPCC. The chemical composition requirements of MR materials are stricter than those of SPCC materials and have fewer impurities. T wo layers of food yellow will be applied to the meat wall of the tinplate coil in contact with the food. This food yellow is resistant to solvents and general acid and alkali, thus ensuring the safety of the food. There is no absolute safety in using iron packaging to hold food. Current technology can fully guarantee the safety of food. MR tinplate coil is a little more expensive than SPCC's. Because MR food grade tinplate coil has very good heat conductivity, many people choose to use it to make kitchen utensils such as cooking pots, baking pans, and steamers. However, special treatments, such as rinsing, frying or boiling water, are required to remove impurities and grease on the surface to avoid harm to the human body before using tinplate for cooking.
