Painted aluminium coil for PP bottle caps

[xuanxuan geng]

The aluminium coil for pp caps produced by Huawei Aluminum have passed the Dos oil treatment and painting procedures. In order to increase the demand for aluminum deep drawing of bottle cap materials, the use of aluminum bottle cap materials in the wine industry is gradually increasing. The working environment of the wine industry is very strict, and the pp cap material is required to have certain tensile strength, yield strength, elongation, compression resistance, deep drawing and other properties. In addition, considering the structure and use environment of the wine industry, wine bottle materials are also required to have better food safety. However, the ordinary aluminum plate used for pp bottle cap material is difficult to meet the performance and safety of this high-strength bottle cap material.

In response to the needs of this industry, Huawei Aluminum has developed enameled aluminum coils for pp caps. This product has high quality, good deep drawing performance, high strength, beautiful appearance and food-grade safety. The hot selling aluminum closure polypropylene cap is 3105 aluminum closure plate. The thickness of the main body of the 3105 aluminum closing plate for bottle cap material is 0.15-0.3 mm, and the state is O, H12, H14, H16, etc. The product advantages of 3105 aluminum for pp caps are:
1. The 3105 aluminum sealing sheet has good electrical conductivity. Due to the addition of 0.3% copper, the conductivity can reach 41%;
2. 3105 aluminum alloy has good anti-rust performance and can be used for various bottle caps and can lids to achieve the effect of long-term beauty of bottles and cans;
3. 3105 aluminum coil is used for pp bottle cap material with good processing performance, novel product shape and long service life;
4. Huawei Aluminum strictly controls the processing quality, texture, particles, and composition of the aluminum seals of pp cap products, and the product performance has reached the international level.
The aluminum bottle cap has strict requirements on the strength, elongation and dimensional deviation of the enameled aluminum coil that closes the pp bottle cap material during the processing, otherwise cracks or creases will occur 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 and free from crazing, scratches and stains. The alloys of painted aluminum commonly used to close pp lids are 8011H14, 3105H16, etc. , The thickness of the material specification is generally 0.20mm ~ 0.23mm. The width is 449mm ~ 796mm.
