There are two kinds of PE protective films. One is without glue, directly co-extruded by polyethylene and adhesive material. This kind is called the mucous membrane, which is unharmful. The other needs glue, generally acrylic glue. And it basically does no harm.
Among all of the protective films made from various materials, PVC film is the only non-environmental-friendly type. You can use the others without worry.
The main components of PE protective film are polyethylene thin film and acrylic glue. Basically, it does not contain substances that are harmful to human body after the production is done. Of cource, the premise is that it's properly used.
