But maybe you will find that some customers don’t need to do the Internal Coating Tin Cans for Air Freshener product, but some customers must need to do the Internal Coating Tin Cans for Air Freshener product.

The Effect for Internal Coating

The inner coating of tin can is a special material, which is suitable to prevent the solvent inside the tin from eroding the inner wall of the tin to prevent the contents from being polluted, and to prolong the storage time more effectively. The internal coating is not only to prevent corrosion, but also to protect the tin can from scratch and rust. For this kind of internal coating, it is non-toxic and harmless, tasteless, with good adhesion, absorption, flexibility, corrosion resistance and high temperature resistance. In the case of high temperature heating, it will not produce harmful substances and lustre and performance.
