Aluminum strip for caps are widely used in the packaging of beverages, alcohol, food, cosmetics, medicines and other products.
We can provide colorful aluminum strip for bottle caps with plain surface, also can provide with surface treatment, like chrome treatment, DOS treatment, color coating, etc. The surface-treated material can completely avoid oxidative damage during transportation.
Aluminum strip is widely used in caps, especially for medicine and cosmetic bottle cap, because the good anti heat and anti wet and high elongation specification. it's very good for medicine bottle caps. Normally it's color coated aluminum strip, coating thickness is around 4~5mic.

The Performance of Aluminum Bottle Cap Strip:
After mechanical properties test, cupping test, anodizing and other tests. The elongation of the material, the punching performance, the earing rate, and the anodizing effect are obvious.
Aluminum strip for cosmetic cap has excellent characteristics such as smooth surface, bright mechanical properties, accurate dimensional tolerance, easy stamping, small ear production after punching into a bottle cap, and good anodizing effect. It is suitable for manufacturing high-grade cosmetic bottle caps.
The Advantages of Aluminum Strip For PP Caps:
1, Stable mechanical properties and good earing , less than 2% steadily or no ears for parts.
2, Good plasticity capable of drawing deepth, at most 75mm,free of "orange peel" after stamping.
3, Better surface quality and uniform fine lines.
4, High thickness precision, up to +0.005mm.
The Application of Colorful Aluminum Bottle Cap Strip:
The cap material process has to go through a number of processes such as hot rolling - cold rolling - annealing - dos oil lubrication -coating - printing- slitting - quality check- packaging, etc.
Wine bottle caps, medical caps, cosmetic caps, soft drink/juice/isotonic/energy beverage caps, cosmetic caps, can caps, vial seals caps, tear off seal caps, flip-off vial seals, aluminium closures, pharmaceutical caps, pull-off aluminum cap, injection vial caps, injection bottle caps.
8011/3105 aluminum sheet will be packed by wooden pallet with net weight 0.8-1 ton per each pallet.There are styles of packaging, which is eye to wall or eye to sky. Customers can choose either of them for their convenience.
Plastic movie and brown paper can be protected at customers’ need. Also timber case or timber pallet is adopted to shield products from harm for the duration of the delivery.
20’ GP FCL can full-load 20 tons by putting 2 layers of pallets of products.
