In optics and electronics, the requirements for PE protective film are extremely high. Any residue or scratch can scrap the product. Several key metrics determine film performance for this sector.
Low-tack, residue-free removal is fundamental. Micro-tack or low-tack silicone-based products are often preferred for screen protection, ensuring zero damage to fragile coatings. Anti-static properties are also critical to prevent dust attraction during peeling. Furthermore, the film's own cleanliness is vital; it must be free of gels or impurities that could mark the protected surface. Matte PE film is also widely used for temporary screen protection to reduce glare or fingerprints.
