Window film principle:

When used in automobiles, film products with various thicknesses and color specifications are generally installed on the inside of the glass, but there are also specialized exterior films. In the event of a collision or explosion, the film reduces the likelihood of glass shattering and can keep broken glass in place for safety.

The film is made from a polyester film layer with extremely high tensile and breaking strength, and is installed with a high-strength adhesive that absorbs energy. When used on cars, Londer Film insulation film can reduce harmful UV rays by 96-99.9%, depending on the film used. In addition, many films can reduce glare by more than 90% and solar gain by 77%.
