Pre Painted Aluminum Sheet Metal for Screw Cap

Aluminum's barrier properties are the primary reason it is used in threaded bottle caps to prevent food spoilage. Blind taste tests by wine experts have proven that aluminum screw caps preserve wine more consistently than cork stoppers without adversely affecting the quality of the wine.

Aluminum bottle caps come in a variety of styles and widths. It offers stability and stiffness compared to other bottle cap material. Aluminum caps and closures are frequently used in the food and beverage industry. The raw material of aluminum covers is pre painted aluminum sheet metal or printed aluminum sheet. Aluminum covers of different specifications need to be produced with aluminum alloy plates of different specifications.

It usually choose 8011 aluminum alloy. It satisfies the following requirements like high dimensional accuracy, low flatness, smooth surface, low ear rate, and good strength after baking. It is suitable for liquor bottle caps, red wine bottle caps, cosmetic bottle caps, milk powder caps, medical caps, beverage caps, yogurt caps, etc.

No matter it is the coated or printed aluminum sheet, Haomei Aluminum uses harmless, low-volatile organic solvents and does not contain harmful substances such as formaldehyde, heavy metals, benzene, etc. It has passed multiple quality and safety certifications, such as European REACH regulations and US FDA certification.

Because bottle cap materials have very strict quality requirements for aluminum sheet surface and shape, uring the hot rolling process, it is necessary to control product quality by controlling processing parameters, optimizing processes, and manual inspection. In terms of rolling, based on our many years of experience in producing bottle cap materials and equipment performance, and according to different blank widths and finished product thicknesses, the rolling passes of cold rolling and foil rolling are specified to ensure the surface and shape of the finished product.

The elongation of the printed alu sheet determines the degree of deformation of the side pattern. No matter how high-quality the aluminum plate is, it will deform to a greater or lesser extent. The higher the height of the bottle cap, the more serious the downward deformation of the pattern will be, so try to place the pattern upward and avoid knurling, cuts, and spiral patterns. It is recommended to choose the side roll printing process for bottle caps with a height exceeding 35mm. For bottle caps with a height higher than 24mm like 24mm aluminium screw cap, try not to design a straight pattern. You can design a diagonal pattern so that no stretch deformation is visible visually.
