AI Technical Summary
Traditional thick silicone lettering films are prone to tearing or deformation when subjected to significant external forces, and have a short service life in applications involving frequent bending or stretching. The lack of effective reinforcement measures leads to severe wear and aging.
A reinforcing layer is set in the silicone layer, using ultra-high molecular weight polyethylene fiber as the reinforcing fiber, and elastic structures and double transparent protective layers are set on both sides to increase tear resistance and deformation resistance. At the same time, the outer protective layer can be peeled off when worn, extending the service life.
It improves the tear and deformation resistance of silicone lettering film, meets the needs of frequent bending or stretching, extends service life and maintains aesthetic effect.
