1060 and 8011 Aluminum Bottle Cap Material

There are two commonly used aluminum bottle cap materials: 8011 and 1060 alloy. What are their properties?

Aluminum foil for bottle cap material is of washing grade A and has a low ear-making rate. Compared with plastic bottle caps, aluminum bottle caps not only have better performance, but are also low-cost, pollution-free, and recyclable, so they are favored by users.

Aluminum foil 8011 is a widely used bottle cap material on the market. The tempers are H14 and H16. The thickness range is 0.15-0.27mm, and the width range is 330-1000mm. It is suitable for liquor bottle caps, red wine bottle caps, cosmetic bottle caps, milk powder caps, medical caps, beverage caps, yogurt caps, etc.

Because bottle cap materials have very strict quality requirements for aluminum sheet surface and shape. Therefore, during the hot rolling process, it is necessary to control product quality by controlling processing parameters, optimizing processes, and manual inspection. Haomei Aluminum has a control of the rolling passes of cold rolling and foil rolling according to the different blank width and the finished product thicknesses to ensure the finished plate surface and shape.

To determine whether the 1060 aluminum plate is suitable for contact with food, you first need to understand the physical properties of the aluminum plate. 1060 aluminum plate has high strength and corrosion resistance, and is easy to process and form, so it is widely used in food packaging materials.

In addition to physical properties, the chemical properties of aluminum plates also have a great influence on whether they are suitable for contact with food. The 1060 aluminum plate itself is a relatively stable metal material and will not react chemically in conventional food environments. However, if there is corrosion, oxidation and other phenomena on the surface of the aluminum plate, aluminum ions harmful to the human body may be released, thus causing food hazards.

To evaluate whether 1060 aluminum sheets are suitable for food contact, processing technology factors need to be considered. The following is an introduction to several dimensions:

1. Choose high-quality raw materials to ensure compliance with food hygiene requirements.

2. Use advanced production equipment and technology to ensure the surface smoothness of the aluminum plate and avoid scratches.

3. Use appropriate surface treatment techniques, such as polishing, sandblasting, etc., to improve the surface quality of the aluminum plate.

4. Use appropriate surface treatment techniques, such as polishing, sandblasting, etc., to improve the surface quality of the aluminum plate.

5. Strictly control the processing environment to prevent contamination and cross-contamination.

6. Detect and control the chemical composition and physical properties of aluminum plates to ensure compliance with food reliability requirements.

7. Only under the guarantee of the above-mentioned processing technology, 1060 aluminum can be reliably used in making bottle caps.

Testing is one of the important means to ensure the reliability of aluminum plates in contact with food. The testing standards for 1060 alloy usually include aluminum ion release, heavy metal content, bacterial count and other indicators. Only aluminum plates that meet testing standards can be used in food packaging materials to ensure the reliability of contact between aluminum plates and food.
