Title
(EN) Waterborne polymers for heat seal adhesive
(ZH) 用于热密封粘合剂的水性聚合物
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 DEG C and an ethylene-vinyl acetate copolymer dispersion in water, blocking resistance up to 50 DEG C, heat seal-ability under reasonable conditions of contact time, temperature and pressure, good adhesive properties, and approval for food contact.
(ZH) 本发明涉及用于中至高水分食品包装的可热密封粘合剂组合物。粘合剂包含具有接近或25℃以下的最小成膜温度的在水中的胶乳,乙烯‑乙酸乙烯酯共聚物水分散体,其具有达50℃的抗粘连性,在合理的接触时间、温度和压力条件下的热密封性,良好粘合性能并批准用于食品接触。
