One of the core technologies of self-adhesive printing paper is pressure-sensitive adhesive technology. The adhesive layer uses a high-molecular-weight pressure-sensitive adhesive material, achieving adhesion with light pressure at room temperature, without the need for additional heating or solvents. By improving the adhesive formulation, different adhesion requirements can be met, such as permanent adhesion, removable adhesion, or reusability, thus adapting to various surfaces and application environments, including smooth metals, plastics, paper packaging, and even low surface energy materials.
Another key technology is surface coating and printability technology. The printing surface layer of self-adhesive printing paper undergoes a special coating treatment, making it compatible with inkjet, laser, or thermal printing equipment. The coating not only ensures rapid drying and adhesion of ink or thermal materials but also prevents smudging, blurring, or fading of printed content. Self-adhesive printing paper also involves backing paper protection and release technology. The backing paper is typically coated with silicone oil or a smooth film to protect the integrity of the adhesive layer during storage, transportation, and mass use, while ensuring that the label can be easily peeled off without damaging the adhesive layer or the printing surface. Advanced release technology can also improve the efficiency of automated printing equipment and prevent labels from sticking, wrinkling or clogging during high-speed printing or automatic labeling.
