Process instrumentation & controls offer coding inks. These controls are specially developed for coding and marking on aluminium foils used in various drug packing and pharma industries. These coding inks work on plastic, varnish-coated paper, laminated surfaces, blisters/strips and other non-porous surfaces. They are used to code batch number, date of manufacturing, expiry date, retail price, shipment number, etc, on the packed drugs. The blister-pack coding inks are free-flowing, high-gloss, limpid and have optimum resistance to lubricants and other liquids. The print/impression from these inks is very sharp and indeliable. These inks do not dry on cartridges/rollers for a long time, but are fast drying on printing substrates with clear and precise impressions. The coding inks are available in all major colours and packing sizes at very competent prices.
