Clear lacquer aluminum coil and sheet for pilfer proof caps is a kind of aluminum sheet material used for manufacturing bottle caps. This kind of aluminum is lightweight, beautiful, durable and easy to process, so it is widely used in the manufacture of various bottle caps. Aluminum coil and sheet for PP caps is usually made of aluminum alloy, which has excellent mechanical properties and corrosion resistance. At the same time, lacquered aluminum coil and sheet for bottle caps also has good plasticity and ductility, can be processed into a variety of shapes and sizes of bottle caps.

During the production process, the clear lacquer aluminum coil and sheet for pilfer proof caps needs to undergo a series of processing and treatment, such as cutting, stamping, bending, etc., to get the final shape and size of the cap. These operations may leave marks and damages on the surface of the aluminum coil and sheet, and the application of varnish can protect the surface of the aluminum sheet from damage during processing and use. In addition to 3105 lacquered aluminum coil and sheet for pp caps, there are other aluminum alloy materials that can be used to manufacture bottle caps, such as 8011 alloy. These materials have different mechanical properties and corrosion resistance, and can be selected according to the actual needs.

The main reasons for applying clear varnish on clear lacquer aluminum coil and sheet for pilfer proof caps are as follows:

Protect the cap material:

Clear varnish can protect the aluminum sheet for pilfer proof caps from external environmental factors (such as ultraviolet rays, humidity) and prevent it from aging, discoloration or deterioration.

Increase the aesthetics:

Transparent varnish coating can make the bottle cap look more beautiful, bright, enhance the overall texture of the product.

Anti-skidding effect:

Transparent varnish can form a layer of smooth coating on the surface of the bottle cap, which plays the role of anti-skidding and makes it convenient for users to open the bottle cap.

Prevent liquid leakage:

For some bottles containing liquids, clear varnish can prevent liquid leakage and improve the sealing performance of the product.

Extend the service life:

Clear varnish can protect the aluminum coil and sheet for pilfer proof caps from microbial erosion, thus extending the service life of the product.

Increase adhesion:

Coating the aluminum sheet for pp caps with varnish can increase its adhesion and make it easier to adhere to other objects.

Prevent oxidation:

Varnish can prevent the aluminum coil for pp caps from being oxidized when exposed to air.

To summarize, clear varnish on clear lacquer aluminum coil and sheet for pilfer proof caps can play the role of protection, beauty, anti-slip, preventing liquid leakage and prolonging service life.
