The self-adhesive label is a composite material made of paper, film, or special materials, with the adhesive agent on the back and silicone-coated paper as the base layer. There are normally two types of self-adhesive labels, namely the paper-type self-adhesive label which is used mainly on liquid detergent products and personal care products, and the film-type self-adhesive label which is normally made from PE, PP, PVC, and other synthetic materials. Film materials are mainly white, matt, and transparent.
