随着环保法规的严格和环保意识的增强以及制造软包装材料的环保要求,环保型复膜胶备受青睐。虽然水性复膜胶无毒不污染,但因干燥速度慢、复合强度低、耐水性较差,而使推广应用受限。传统的溶剂型复膜胶多含苯类溶剂,有害健康,污染环境。目前,欧洲一些发达国家都已普遍采用环保型复膜胶,在40%的溶剂型复膜胶中醇溶性复膜胶超过95%。醇溶性复膜胶以乙醇为溶剂,对人体危害
With the stringent environmental regulations and environmental awareness and the environmental protection requirements of manufacturing flexible packaging materials, environmentally friendly adhesive is favored. Although water-based adhesive non-toxic non-polluting, but due to slow drying, low composite strength, poor water resistance, but to promote the use of limited. The traditional solvent-based adhesive plastic compound containing benzene, harmful to health, pollute the environment. At present, some developed countries in Europe have generally adopted environmentally-friendly laminating adhesive, more than 95% of the alcohol-soluble laminating adhesive in 40% solvent-based laminating adhesive. Alcohol-soluble adhesive to ethanol as a solvent on the human body hazards
