A natural flavor component used in food products reportedly can make EPS bead foam packaging degrade rapidly when exposed to sunlight. SunBrite Packaging Co. in Largo, Fla., proposes to dissolve the additive in the blowing agent used to make EPS beads. No change would be necessary in molding cups and other food containers, but when exposed to sunlight, the EPS would turn brown and brittle and break down into a fine powder and eventually to CO2 and water. SunBrite is looking to license the technology and supply the additive. SunBrite has completed most of the FDA testing of the material for indirect food contact (it was already approved as a direct food additive). SunBrite also has to be sure the additive won’t affect the flavor of food contained in cups or other packaging. (866) 329-9262 • www.sunbritecups.com
