In the modern packaging industry, wide-mouth bottle aluminum cap has become an important packaging component in the fields of food, medicine, cosmetics, etc. Its light weight, beautiful appearance and strong sealing properties are due to the reasonable selection of aluminum alloy materials, mainly 1xxx, 3xxx, 8xxx series aluminum alloy plates, and the most commonly used is 8011 aluminum foil.

Wide-mouth bottle aluminum cap mainly uses 8011 aluminum alloy. This alloy is widely used in life because of its light weight, good sealing effect, beautiful appearance and easy printing. Specifically, wide-mouth bottle aluminum cap is generally made of 8011-H14 and 8011-H16 aluminum foil, which requires the aluminum foil surface to be smooth, clean and oil-free, without cracks, bubbles, through pores, metal and non-metallic indentation, light and dark stripes and other defects.

Compared with plastic bottle caps, aluminum bottle caps have the advantages of simple appearance, fine workmanship, no pollution, and recyclability.

8011 aluminum alloy bottle cap material specifications:

Basis for selecting alloy models for wide-mouth bottle aluminum caps:

1. Sealing: prevent contents from leaking or being contaminated by the outside world.

2. Corrosion resistance: anti-oxidation, adapt to the acidic and alkaline environment of food, beverages or chemicals.

3. Strength and toughness: It must have sufficient strength to resist impact and good ductility for easy processing and molding.

4. Decorativeness: The surface is easy to paint and anodize to meet the aesthetic needs of the brand image.

5. Processability: Aluminum alloys are easy to stamp, stretch and form, so they are very suitable for making aluminum caps of various shapes.
