1060 and 3105 Painted Aluminum for ROPP Cap

Aluminum sheet is one of the commonly used bottle cap material to make ropp caps ( roll-on-pilfer-proof), Aluminum bottle caps can be used to package various alcoholic, beverage and pharmaceutical and health care products. It can meet special requirements such as high-temperature cooking and sterilization and has beautiful appearance.

Compared with traditional plastic bottle caps, aluminum bottle cap materials have good sealing properties and do not leak. The bottle cap made of 3105 painted aluminum sheet can be used for large-area precision printing, multi-color printing, side roll printing, etc. The design space is large, the colors are easy to match, the saturation is good, and the smoothness is high. In addition, low cost, good food safety, and recyclability are also the advantages of aluminum ROPP caps.

1060 aluminum sheet is more often used in the cosmetics industry, and some is also used in the pharmaceutical industry. The thickness is generally 0.17- 0.5mm. For applications requiring high elongation, excellent conductivity, high formability or other conventional processing (stamping, drawing) conditions, as well as the price of 1060 aluminum alloy, 1060 aluminium sheet is one the ideal choices.

Commonly used coatings for roller coating of painted aluminum

Commonly used coatings for roller coating of aluminum sheets include epoxy resin paint, polyester resin paint and fluorocarbon resin paint.

Food contact materials have dual significance for food safety: firstly, compliant materials can protect food from contamination from the external environment and keep the moisture, composition, quality and other characteristics of the food from changing; secondly, the chemical components of the material itself may migrate into food. When the migration exceeds a certain amount, it will affect the hygiene and safety of the food in contact with it.

What is the difference between food grade testing and general chemical testing?

General chemical testing mainly focuses on the amount of harmful substances contained in materials and products, while food-grade testing focuses more on the amount of harmful substances that migrate from materials and products to foods that come into contact with them under normal use conditions.

Haomei Aluminum’s bottle cap material all adopts food grade coating. It does not contain harmful substances such as formaldehyde, heavy metals, benzene, etc. Food-grade environmentally friendly paint also performs well in terms of painting effects, providing a wide range of color choices and gloss to meet different painting needs.

Haomei Aluminum controls the chemical composition of the aluminum bottle cap material, rolling temperature, time and annealing temperature to provide the best product material to meet the customer's performance needs, such as its opening performance and ear-making rate.
