A self-adhesive label is a label that uses a special adhesive to adhere to the surface of a substrate. The main material of the label is composed of three parts: surface material, glue and backing paper.

Surface materials include:

Plastics: PVC, PET, PP and PE, etc. PVC has high transparency and high tensile strength, making it one of the better materials. PET has good toughness, high transparency, and good resistance to strong pressure and friction. PP has excellent chemical stability and good physical stability, and performs well in high and low temperature environments. PE is soft, has excellent insulation properties and stable power consumption performance.

Paper type: thermal paper, coated paper, white card and other types. Cellophane is suitable for most labels and has stable tearing properties. Coated paper has a smooth surface and is suitable for high-speed printing. The white cardboard has a smooth surface and is suitable for labels on high-end products.

Glue is divided into water-based glue, oil-based glue and hot melt glue, and the color is mostly transparent or yellow. Ordinary self-adhesive labels usually use hot melt glue and oil-based glue, while water-based glue is used for labels in some environmentally friendly or special application fields. The main function of glue is to stick the label firmly to the substrate.

To sum up, self-adhesive labels are mainly composed of three parts: surface material, glue and backing paper. Different combinations of materials can be suitable for different usage environments and application scenarios.
