Safety and security window films are polyester films that are applied to glass and glazing in order to hold them together if the glass is shattered (similar to laminated glass). The main difference between film and laminated glass is that the film can be applied to the glass or glazing after manufacture or installation, i.e., it is a retrofit product. These films are used widely all over the world; they can be found on trains, buses, cars, and buildings.The films are adhesive coated to bond them to the glass. The better safety films are smooth-coated, because they have far superior optical clarity.Safety and security window films are designed to perform under adverse conditions.

It is advisable for any prospective user to ensure that his or her supplier can produce certification for such codes and standards.
