Our smart film product is a self-adhesive film that is applied to existing glass, transforming it into switchable glass. Electric privacy film works just like electric privacy glass, going from transparent to opaque with the flick of a switch. The adhesive film is actually the same PDLC film that is laminated within our glass product. It is ideal for situations where there is already glass in place or for those who are looking for a more economical alternative to our smart privacy glass.
