Color coated aluminum sheet for aluminum screw caps is a material that is painted and colored on the surface of the aluminum substrate, and is usually used in the manufacture of aluminum screw caps. 3105 H14 H16 aluminum cover sheet has the advantage of high strength and can withstand sufficient air pressure. It is widely used to seal bottles and containers in various industries such as beverages, medicines and cosmetics.

MC Aluminum can customize the color of aluminum nut sheet. On the basis of ordinary sheet, 3105 aluminum screw cap sheet can be chromated with phosphate and coated with DOS to print different colors. The choice of coating color may vary depending on the brand requirements of the product, and is usually customized according to the brand logo or packaging design.

3105 Aluminum closure sheet requirements for screw caps:

1. The surface shall not have scratches, scrapes, bruises, cracks, bubbles, stains, unevenness, distortion, corrosion and other defects that are harmful to use, and shall not have oxidation.

2. The tolerances of material thickness, width, length, etc. should be controlled within a certain range to ensure that the flatness and sickle bend of the plate meet the standards.

3. Not easy to deform after shearing.

3. Strictly control the material composition, rolling temperature and time, annealing temperature, etc. to meet customer requirements for performance such as hole opening capacity and ear forming rate.
