Aluminum bottle cap is widely used for food, beverage, medical bottle packaging. The color coated aluminum sheet is a commonly used aluminum bottle cap material. Its coating must meet food grade.
There is no exact definition of what a material is "food safe". However, some requirements must be met in any case. These include, for example, the food compliance requirements of the US Food and Drug Administration (FDA), the Federal Office for Risk Assessment, and the requirements of EU Regulation No. 10.2011. In principle, a material is considered food safe if it can come into direct contact with food without posing any health risk. This means:
1. It does not release any taste or odor to food.
2. Consuming food after contact with the material will not endanger human health.
3. The material does not release or releases very little free components into food

3. Spray within 4 hours after surface treatment is completed to avoid other quality problems.
What is adhesive lacquer
The adhesive lacquer is a food-grade adhesive designed specifically for screw bottle caps. It has good adhesion to paste PVC, and excellent anti-corrosion performance and surface strength. It is used with FC3100-0 / FC3100-2 adhesive primer.
