Hongchang Aluminum supplies aluminum sheets and coils for the manufacture of bottle caps, which are ideal materials for PP caps for whiskey bottles and other beverage bottles. It has exnt moisture-proof, anti-seepage and anti-counterfeiting properties, making it truly safe, healthy, fast and environmentally friendly, increasing the added value of the product.
The production of PP bottle caps has strict requirements on the strength, elongation and dimensional deviation of the material, otherwise cracks or creases will appear during the processing. In order to ensure the convenience of printing after the bottle cap is formed, the surface of the bottle cap material is required to be smooth. No roll marks, scratches and stains. Commonly used alloys include 8011-H14, 8011-H16, etc. Aluminum bottle cap materials can be produced by hot rolling, continuous casting, continuous rolling or cold rolling.
