Dow introduces new CANVERA coating polymer

New technological developments from Dow Coating Materials have facilitated the application of thermoplastic polyolefins in plastic food packaging to can coatings. The new CANVERA includes a specially designed mix of functionalized and non-functionalized polyethylene or polypropylene in an aqueous dispersion.

Without materials such as styrene, epoxides and phenolic crosslinkers, CANVERA Polyolefin Dispersions from Dow offer a water-borne, spray-applied replacement for epoxy coating systems, according to Dow.

CANVERA eliminates BPA use and provides a new approach to safe, sustainable can coating that may appeal to health-conscious consumers, the company claims.

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 color, taste or appearance.

According to Dow, the technology can be used on existing lines and applied directly to metal surfaces by the same equipment used for current epoxy coatings.
