Material Notes:

Melinex® ST730 is an optically clear, heat stabilized polyester film which is differentially treated on both sides. One side provides exceptional adhesion to both solvent based and UV curing inks and lacquers. The other side provides in addition to exceptional adhesion properties, unique UV Multipass exposure resilience. These characteristics make Melinex® ST730 film particularly suited for the graphics layer of membrane touch switches with a multifold exposure to UV.Approvals: UL 94 VTM-2 - for 500, 700, 1000 gauge (0.13, 0.18, 0.25mm)Information provided by DuPont.
