Safety and security film is manufactured from single or multiple layers of tough, optically clear polyester film laminated together in a variety of constructions. One side of the film is coated with an extremely powerful adhesive formula that is applied to the interior surface of the glass, whilst the exterior (room facing) side is protected with a special scratch-resistant coating.  Safety and security window films adhere to the glass and act as a protective layer to make the glass stronger and harder to break. The film also helps to secure shards and splinters if the glass should shatter.
