Next generation, award-winning technology from Dow Coating Materials could drive a revolution in can coatings, by facilitating health-conscious food and drink producers to turn away from epoxy coatings using bisphenol A (BPA) and other materials of concern. Whilst cans offer great consumer convenience, coatings are needed to protect containers from corrosion, and the contents from contact with metal, helping preservation, flavour quality and consumer safety. Dow has facilitated a tried and tested option for flexible and rigid plastic food packaging to be applied to can coatings too. Powered by patented BLUEWAVE™ Technology, which facilitates creation of ultra-thin, thermoplastic film coatings, CANVERA™ Polyolefin Dispersions can be spray-applied from water-borne formulations to the inside of cans, protecting contents from changes in colour, taste or appearance. The technology can be used on existing lines and applied directly to metal surfaces by the same equipment used for current epoxy coatings.
