Food label stickers are used on food packaging to explain and decorate. Different packaging boxes or bags use labels of different materials, usually PET, PVC, coated paper, kraft paper, and synthetic paper. Color printing, hot stamping, embossing and other processes can be used in printing. Various materials have their own characteristics and advantages. The stickers all use environmentally friendly glue, which is waterproof, oil-proof and anti-corrosion.
