Aluminium closure sheet printing process
Foundation processing(Known as a “size coat,” foundation processing is conducted to help the paint adhere better. Products that are processed using phosphoric acid chromate or zirconium are often cut.)
Exterior (interior) paint Either the public side or the product side surface may be painted first, depending on the product.
Exterior printing (The number of printing passes depends on the image to be printed on the cap).-Topcoat varnish Glossy varnish
Cutting (A single slitter method is used to cut the sheet into three equal strips. For some products, both edges are trimmed at this time).

 

Aluminium closure sheet pressing process
First pressing
The cut printing plate is run through the press to create the cap shape (straight side walls).
Second pressing
The bottom edge of the formed cap is trimmed off (broken off) or curled.
Attaching the liner to the inner surface
Adhesive joining
Knurl forming
Protrusions are formed on the sides of the cap, near the top, to prevent slippage when twisting the lid open.
Perforations
Perforations are added to ensure that when the lid is twisted open, the TE band (ring) remains behind.
