Coding foils are commonly used for printing information such as manufacturing dates, expiry dates, batch codes, and other product information onto packaging materials. Foils are available in various types and sizes depending on the printing technology and the width of the printing equipment.
Types: Coding foils are typically classified based on the printing technology used, which can be thermal transfer or hot stamping. Thermal transfer foils use heat to transfer ink onto the packaging material, while hot stamping foils use pressure and heat to transfer a pre-printed image onto the material. There are also specialty foils available, such as UV-readable foils, that allow for additional security features and anti-counterfeiting measures.
Sizes: Coding foils come in different widths to accommodate different types of packaging materials and printing equipment. Common widths include 25mm, 30mm, 35mm, and 50mm.
In summary, coding foils are used to print important product information onto packaging materials and come in different types and sizes based on the printing technology and width of the printing equipment.
