Self-adhesive, also known as self-adhesive label material, is a composite material with paper, film or special material as fabric, adhesive coated on the back and silicon-coated protective paper as backing paper. There are many kinds of coating technologies, resulting in different grades of quick-drying adhesives. At present, the development direction is from traditional roll coating, blade coating to high-pressure tape casting coating, so as to ensure the uniformity of coating, avoid bubbles and pinholes and ensure the coating quality. However, the tape casting technology is not mature in China, and the traditional roll coating is mainly used in China.
