Multilayer labels are special labels that combine thermal paper, a PP layer, and self-adhesive materials through a composite process, commonly used in logistics, electronics, and anti-counterfeiting fields. Their core design lies in achieving functional integration through a layered structure: the top layer is used for information printing, the middle layer enhances structural stability, and the bottom layer provides adhesion.
A typical multilayer label structure consists of three layers: the top layer is thermal paper, which develops color through a thermal reaction, allowing information to be printed without a ribbon; the middle layer is a PP (polypropylene) film, which enhances tear resistance and moisture protection; and the bottom layer is a self-adhesive layer, providing adhesion. Some products also incorporate an anti-counterfeiting coating between the PP and self-adhesive layers, enhancing security through comprehensive anti-counterfeiting technologies (such as fluorescent ink and microtext). Their operating temperature range is -20℃ to 70℃, allowing them to adapt to extreme environments; and the design with a rated voltage below 440V ensures their safety in electronic device labeling scenarios.
