What Are Window Films Made Of ?

Kunlin Window films are made from different materials, depending on their specific properties and intended use. At present most window films are made of PET or PVC. 

Polyethylene terephthalate (PET) is a good and higher price material  for its performance . PET is a form of thermoplastic polyester that has excellent optical clarity, high strength, and chemical resistance. It is also highly transparent to visible light while blocking UV radiation. As such, it is often used in solar control films and anti-glare films. For example building solar film, car windows tint film.

Polyvinyl chloride (PVC) is popular, toughness, moisture resistance, and low cost material for its widely used. PVC is a thermoplastic material that has excellent flexibility, durability, and resistance to weathering. It is commonly used in privacy films and safety and security films due to its ability to hold broken glass together after impact. For example home bath glass sticker, kitechen / door decorative glitter glass film which is frosted or etched effection.

For different usage situation, Kunlin Window films may add various additives and dyes to enhance their optical, mechanical, and adhesion properties. For example, Car UV-blocking films may contain metal or organic dyes that absorb or reflect UV radiation. Anti-glare films may contain micro-embossed particles that scatter light and reduce glare. Adhesives used in window films can be either pressure-sensitive or heat-activated and are designed to provide strong and long-lasting bonding to the glass surface. 

However, as film technology is developing , more and more amazing films are creating, the exact composition and manufacturing process of window films depend on the specific type of film and its intended use. High-quality window films are typically tested and certified to meet industry standards and regulations related to safety, flammability, optical clarity, and durability.
