d) If thermal paper touches anything which includes phthalic acid ester
plasticizer for a long period, it can reduce the image formation ability of the
paper and can cause the printed image to fade. When storing thermal
paper in a card case or sample notebook, be sure to use only products
made from polyethylene, polypropylene, or polyester.
