What is the difference between food grade tinplate and ordinary chemical tinplate? What is the difference between MR material and SPCC?

Answer:

Tinned food grade and non food grade. The main brands are MR and SPCC. because the meat food will be wall mounted in contact with food tin coated with two layers of yellow food, the food is yellow anti solvent, anti general acid-base, thus ensuring the safety of food packaging containing iron. The food there is no absolute security argument, now the technology has been fully capable of ensuring the safety of food containing.MR's impurity is a little more than SPCC, and the price is a little high. It's OK to use SPCC to spread two layers of food on the outside
No general food grade and ordinary chemical tinplate tinplate. There are some major is not mature in domestic tin (MR, L, D) the production of tinned steel substrate outside, technology is not mature, not environmental protection, so there is a risk for food cans, can only be used for chemical tank.
The chemical composition of MR material is more strict than that of SPCC material, and the impurities are fewCanned fish must be made of good quality MR material, which reduces the risk of canning
