DuPont Teijin Films manufacturers several types of film for the screen-printing of the top and bottom circuits of membrane switches. Melinex ST® is heat treated for low shrinkage and dimensional stability and is pretreated for adhesion to multiple passes of a wide range of conductive inks, dielectric inks, varnishes and solvents.

All polyester films from DuPont Teijin Films are resistant to moisture, gas, heat and chemical attack, making them perfectly suited for use in medical equipment. These films are also conditioned for excellent handling and accurate screen-printing. DuPont Teijin polyester films are also engineered to resist edge shatter for cleaner die cutting.
