Bostik, a global adhesive company, introduced a copolyester heat seal coating formulation that prevents fog from building up in flexible packaging for refrigerated foods during PACK EXPO International 2018 in Chicago.
The Vitel 1922AF is a 100 percent solids formulation designed for PET lid stock and formulated to reduce fogging from moisture-containing food products that must be refrigerated. With low blocking and good slip properties, this heat seal coating features excellent clarity and seal strengths, providing a smooth yet strong peel from PET trays once sealed.
