Title
(EN) Waterborne polymers for heat seal adhesive
Abstract
(EN)

This invention relates to a heat sealable adhesive composition for packaging for moderate to high moisture food products. The adhesive comprises latex in water with a minimum film formation temperature near or below 25° C. and an ethylene-vinyl acetate copolymer dispersion in water, blocking resistance up to 50° C., heat seal-ability under reasonable conditions of contact time, temperature and pressure, good adhesive properties, and approval for food contact.
