Material Notes:
Melinex® ST328 is an exceptionally white, opaque film with a satin finish. It is pretreated on both surfaces to promote adhesion to a wide range of solvent-based and UV-curable graphics inks and varnishes, silver conducting inks and dielectrics, and has been heat stabilized to give excellent dimensional stability at temperatures up to 302°F. Typical Applications: Melinex® ST328 has been developed for use in screen-printed medical test strips where a white background appearance is required. The tight thickness control of this film ensures reliable insertion into reading devices.Information provided by DuPont.
