The adhesive type is a core technology of PE protective film. The three mainstream types are water-based, solvent-based, and silicone-based adhesives. Their chemical properties determine the film's performance in different applications.
Water-based adhesive uses water as a solvent, making it highly eco-friendly. It provides stable adhesion and clean removal on most smooth surfaces like acrylic sheets and high-gloss metal sheets, making it an ideal choice for general purpose. Solvent-based adhesive generally offers higher initial tack and better weather resistance, making it suitable for outdoor use or environments with temperature fluctuations. Silicone adhesive, known for its excellent high-temperature resistance and low tack, is widely used in the optical and electronics sector, ensuring zero residue on delicate surfaces like screens and lenses.
When choosing an adhesive type, consider the material being protected, environmental conditions, and how long the protection is needed. For products stored outdoors long-term, solvent-based films may be more reliable.
