Bayfol® CR polycarbonate (PC)/polyethylene terephthalate (PET) polyester film provides a gloss/micro-matte finish for membrane switch applications—such as kitchen appliance control panels with see-through windows—that reportedly allows easier embossing and improved ink adhesion. The Bayfol CR film is said to be the first material in the membrane switch market to compete with PET films for use in see-through window applications found on microwaves, ranges, washers, and medical IV monitoring equipment. The Bayfol material is reportedly able to overcome problems that have affected PET-only membrane switch overlays, such as faceplate cracking.
