Product Description:

Cans cover (ring) pre-coated plates
First, the raw materials
Aluminum lid and pull the main substrate of aluminum from the southwest andNanshan Aluminum, the use of aluminum-magnesium alloy 5182H19, 5052H19. Itsproducts in the normal substrates of manganese and magnesium components addedto increase the tensile strength and elongation. Han and the lotion by theGerman food-grade chrome HD agent, the United States PPG epoxy phenolicpackaging coatings, and high-end DOS oil
Second, applications
Division I professional production of DOS card and aluminum cans with a coatingfor cans of the lid and pull the coated aluminum is widely used in beverage,beer, rice pudding, tea, cigarettes, cans and other products packaging. U.S.imports of food ash using electrostatic spray wax, cut by large waves, transverseshear, longitudinal easily processed into the system covered the pre-coatedaluminum manufacturers. Depending on the system covers equipment can makeweight and volume of different specifications to meet customer requirements.
Third, the application prospect
Cans of food packaging as lightweight, unbreakable, easy to carry transportcharacteristics, cans packaged foods will gradually replace the glass packagingfood. As China'seconomy continues to strengthen, improve people's living standards, consumptionwill be more and more cans, cans will be growing timber. Therefore, cans withthe amount of pre-coated aluminum coil will be more and more broad prospects.

Appearance

The surface of the pop cans cover coatingdoes not allow defects such as air bubbles, scratches, missing coating,over-burning, oil spots, stains, streaks, color, piebald, roller printing,embossing, periodic prints, chemical liquid etc which impact users.

Each coil allowed a joint which does notallow loose layer or dislocation, the joint can only be overlapped, which needto make the mark in the end, and each batch coil of joint  is not morethan 10% of the total number of coils.
