electromagnetic shielding  film

EMS (Electromagnetic shielding) film is a kind of transparent shielding material, which blocks electromagnetic wave penetrates the glass, prevent electromagnetic radiation, protect the electronic information from disclosure, resistance to electromagnetic interference. Through the vacuum sputtering method, high conductive surface layer containing silver, copper and other metal deposits on the transparent polyester film, which is how electromagnetic shielding film is produced. It can be directly sticked on common glass or organic glass surface, to shield EMI electromagnetic interference and protect electromagnetic radiation; since the film itself has protective layer, it can be used in bad working environment
