Product Description

Role and requirements of tinplate metal ear cover coating, metal material for tinplate, upper and lower cover metal packaging materials can be tinplate, chromium plated iron and aluminum, in addition to aluminum will not rust, tinplate and chromium plated will rust when exposed to moisture, the use of coatings can isolate the metal material from the outside world, avoid scratches on the metal substrate, and prevent the erosion of the substrate by corrosive factors in food.

The role of tinplate metal earmuff coating:
a. Container protection.
b. decoration, brand promotion.
c. Help paint iron processing molding.

Requirements For Tinplate Cladding

1. Good storage stability;
2. Solvents in coatings and less harmful to the human body;
3. The coating inside the tank should meet the relevant national health standards;
4. Convenient construction, simple operation, baking and curing to form a good film;
5. After the film is formed, the coating should have the required adhesion and hardness, impact resistance, chemical resistance, compactness and welding resistance together with the substrate to meet the process requirements of can making and lid making
6. Canned food sterilization after cooling, the film should be good appearance, do not fall off;
7. Inner coating shall not affect the flavor and color of food;
8. The inner coating and substrate shall be effective in preventing corrosion of the contents.
