The application of PVD coating technology in food products is mainly related to food safety and hygiene. In food production and processing, PVD can be used to make food contact materials such as food packaging, tableware, kitchenware, etc. PVD coatings in these applications can offer the following advantages:
1) Safety: PVD coatings do not release hazardous substances into food and comply with food safety regulations.
2) Hygienic: PVD coatings have good corrosion resistance and antimicrobial properties, helping to reduce bacterial growth and maintain food hygiene.
PVD coating technology has a wide range of applications, not only limited to food grade, but also in many other fields such as decorations, knives, moulds, architectural glass, flat panel displays, solar energy utilisation, anti-counterfeiting technology, protective coatings for aircraft and so on. In food-grade applications, the main advantage of PVD coatings is their safety and hygienic properties, which provide food safety protection and at the same time meet the high demand for food safety and hygiene. This technology uses physical vapour deposition methods, such as multi-arc ion plating, to form a uniform, dense coating on the surface of the material, thereby enhancing the durability and hygienic properties of the product.
