摘要
液体食品中含有大量的水分、小分子有机物、酸性碱性成分，包装周期中需要长时间与液体接触，这就要求铝塑包装所使用的聚氨酯粘合剂除了具有优异的粘接强度和耐热性外，还需要具有优异的抗介质、耐水解性能。
Liquid foods contain large amounts of water, small molecular organics, and acidic alkaline components.They need long periods of contact with liquids during the packaging cycle which requires that the polyurethane adhesives used in aluminum-plastic packaging have excellent adhesive strength and heat resistance. In addition, it also needs to have excellent resistance to medium and hydrolysis.
