Product Details
The tin can screw-on cap is a type of bottle cap with four or six threads, which is a classic packaging component that combines functionality and aesthetics. Its production integrates metal processing, coating chemistry, and precision mold technology. It has wide applicability and continues to be dynamic in the mid-to-high-end food, beverage, and pharmaceutical sectors today, where consumers increasingly value sustainability, usage experience, and product quality. It can be used for glass bottles, ceramic bottles, and plastic bottles, etc., and has become an important green alternative to plastic screw caps. The main difference between the four-threaded cap and the three-threaded cap lies in the number of threads; the four-threaded cap offers better sealing functionality.
Precautions for using the bottle caps
The tinplate twist off caps of our company have been baked at a temperature of around 200℃, meeting the national food hygiene requirements. Generally, they do not need to be cleaned. In special cases, such as in cold filling, if they are soaked in water at a temperature above 80℃ for 5 to 10 minutes before sealing, the sealing effect will be better. The surface of the sealing glue of the twist off caps has a lubricating effect of wax. The melting point of the wax is 82-85℃. The selected wax is in line with the hygiene and safety of food packaging materials. If you need to remove it, soak it in water at a temperature above 90℃ for 5 to 10 minutes. The bottle cap that has been soaked in water needs to be capped within half an hour. Avoid keeping the bottle cap in a humid environment for a long time, as this may cause rusting at the cutting edge of the cap.
