Sun Chemical: Water-based board coatings for food contact

Sun Chemical’s new SunSys resistance coatings are a series of water-based coatings formulated to impart or enhance resistance properties to paper and board substrates while at the same time being FDA-compliant for direct food contact.

Designed to provide resistance to water, grease/oil, industrial chemicals, extreme temperatures, scuffing abrasion, and friction, the SunSys line of aqueous coatings provide converters and brand owners an option to be able to offer a more sustainable and less expensive package, replacing traditional barriers used in the market, such as polyboards and pre-coated boards, as well as wax and laminated films.

“In today’s marketplace, there is a strong demand for convenience and on-the-go meals, but retailers who stock the products packed in paper-based containers with functional and barrier coatings, also want an environment-friendly solution at a lower cost,” says Bob O’Boyle, Product Manager, Coatings at Sun Chemical. “Our new SunSys resistance coatings can be used on boxes, trays, wraps, liners, shells, and bags for fast food, fried/roasted chicken, donuts, baked goods, pastries, frozen food, deserts, microwaveable meals, clam shells, and more. The resistance coatings also allow us to minimize the package structure and are recyclable and re-pulpable, thus reducing the environmental footprint.”

SunSys resistance coatings come with additional features including release properties that block on cold seal applications in a reel, recovery from being frozen, and the ability to be glued, sealed, and formed. SunSys coatings come in a variety of finishes including gloss, satin, and matte, and can be printed on flexo, gravure, and rod coater presses.
