What Material Are Bottle Caps Made of

Aluminum bottle cap materials are a a new type of bottle cap sealing material. They are not only beautiful and easy to open, but also have the function of preventing counterfeit goods. Therefore, it is widely used to the sealing packaging of beverage bottles, wine bottles, cosmetic bottles, medicines, etc. at home and abroad.

The heat seal aluminium foil uses heating to seal the film to the mouth of the container to keep the product fresh, prevent leakage and volatilization, and ensure the safety of product transportation. It is suitable for various containers, like PET, PE, PP, PVC, PS, acrylic, glass, ceramics, etc.

8011 aluminum foil is a commonly used packaging aluminum foil. It has the characteristics of heat preservation, moisturizing, freshness preservation, light protection and anti-penetration. It is used as a food packaging material and has good stability and packaging effect. It is not only safe and hygienic when used for the bottle sealing, but also has beautiful printing and is easy to tear, so it is deeply loved by consumers and cover film suppliers.

Features of the heat seal aluminum foil

1. Safety and health: The surface of aluminum foil is very clean, and no bacteria or microorganisms will grow on the surface of aluminum foil. Compared with other materials, the sealing film made of aluminum foil is safer and healthier for food.

2. No odor: Aluminum foil is a relatively healthy and hygienic packaging material, which is harmless to the human body and will not cause product odor.

3. High quality and low price: The raw material for manufacturing aluminum foil is widely sourced and has high cost performance.

Color coated aluminum sheet for bottle caps mainly uses sheet coating and roller coating processes. Sheet coating refers to DOS pre-treatment first, and then cross-shearing and slitting. Roller coating refers to roller coating directly on the surface of the aluminum coil after cleaning without DOS treatment.

It can be used directly or after cross-cutting. At present, from the perspective of technical process adaptability and large-scale production, roller coating has obvious advantages in the production of color-coated aluminum sheets. Our white painted aluminum sheet is produced by this method.

The aluminum content of 3105 aluminum coil reaches 98%, which can be classified as a pure aluminum alloy. It is slightly stronger than the 1 series alloy with an aluminum content of about 99%. Similarly, 3105 aluminum alloy cannot be strengthened by heat treatment, but its corrosion resistance, formability and welding characteristics are also excellent. Therefore, 3105 aluminum alloy is often used in the manufacture of bottle caps for carbonated beverages.

Haomei Aluminum adopts roller coating process. Even aluminum sheets are rolled and then sheared, which not only ensures thorough cleaning, uniform coating, and consistent film thickness, but also reduces losses and waste. The coating is PPG, VALSPAR, ICI food grade epoxy resin. Welcome to leave message below to inquire what you need.
