Application of plastic coating-Barrier function
In order to improve the circulation cycle and shelf life of commodities, the role of commodity packaging is increasingly important, especially for food, medicine, cosmetics, washing products and other goods with high quality requirements, the use of high-barrier packaging materials is often the most effective means of packaging. The commonly used high barrier packaging film is usually coated with a layer of aluminum on the plastic film by vacuum evaporation or vacuum sputtering.
Recently, people not only require the commodity packaging film to have heat resistance and high resistance, but also require good transparency and excellent microwavability. One of the methods of making high barrier transparent film is vacuum plating SiOx on the plastic film. The inorganic layer of the silicon oxide film is dense and has high barrier property. At the same time, it is high temperature resistant, transparent and has good microwave transmission performance. In addition to SiOx, there are Al2O3, MgO, TiO2, Gd2O3, Y2O3 and other materials that can be used for evaporation and plating.
