随着国内啤酒行业的发展,其包装档次及生产速度都不断提高,以往的聚乙烯醇类及淀粉类商标粘合剂存在耐水性能差,不适合冰柜存放,特别是铝蒸镀纸及金属箔作标签时,毫无耐水性。另外,国内啤酒生产线由原来的20000瓶/时,现提高到30000-40000瓶/时,国外生产线已达到40000-60000瓶/时的速度,这就要求标签胶具有优良的初粘性及高速作业性,淀粉类及聚乙烯醇类均适应不了高速生产的要求,所以,国内外啤酒厂家逐渐转向使用酪蛋白系列粘合剂。
With the development of the domestic beer industry, the packaging grade and production speed are continuously increasing. In the past, polyvinyl alcohol and starch trademark adhesives had poor water resistance and were not suitable for freezer storage, especially for aluminum vapor deposition paper and metal foil For labeling, no water resistance. In addition, the domestic beer production line from the original 20000 bottles / hour, is now increased to 30000-40000 bottles / hour, foreign production lines have reached 40,000-60000 bottles / hour speed, which requires the label adhesive has excellent initial viscosity and high speed operation , Starch and polyvinyl alcohol can not meet the requirements of high-speed production, therefore, domestic and foreign beer manufacturers gradually shift to use casein series adhesives.
