The development of glass protection films

The development of glass protection films has gone through the following stages:

1. Early stage: In the early stage, glass protection films mainly involved applying a transparent coating to the glass surface for protection. These coatings provided a certain level of scratch resistance and anti-contamination properties to protect the glass surface from external substances. However, the protective effect of these coatings was relatively limited, and they were easily damaged and difficult to repair.
2. Tempered glass protection film: With the widespread use of tempered glass, the demand for tempered glass protection films has increased. Tempered glass protection films are usually made of materials such as polyester or polyurethane, offering high abrasion resistance and corrosion resistance. These films effectively prevent scratches, stains, and UV erosion, while also providing additional safety by preventing glass splintering upon breakage.
3. Blast-resistant protection film: With the growing concerns for severe weather and safety, blast-resistant protection films have been applied to glass windows and exterior wall glass in buildings. These protection films are typically composed of multiple layers of polyester film, offering strong impact resistance. When the glass breaks, the film can effectively control the splintering of glass shards, reducing the risk of injury.
4. Smart protection film: With technological advancements, smart glass protection films have emerged. These films can adjust their transparency using electrical signals or light control technology, providing privacy protection and solar control functions. Smart protection films are widely used in architectural glass, vehicle windows, display screens, and other areas, offering enhanced convenience and comfort.
5. Self-healing protection film: In recent years, self-healing glass protection films have become a focus of development. These films are typically made of polymer materials and possess self-healing capabilities. When the film’s surface experiences minor scratches or abrasions, the molecular structure within the film can rearrange and repair itself, allowing the scratches or abrasions to be healed and restoring the film to its original state.

With ongoing technological advancements, glass protection films continue to improve in functionality, durability, and safety, providing a wider range of choices and protection for various glass applications.
