With its Optal XP product series, a German company has developed a completely new generation of synthetic adhesives for glass bottle labeling that offers an excellent performance spectrum. The brewing industry has relied for many years on tried and trusted waterbased casein adhesives to label its glass bottles. Constantly rising prices for casein are, however, driving up the costs for these conventional labeling adhesives. Given that casein is a raw material derived from cow's milk, the beverage industry's adhesives budgets are also affected by sharp periodic swings. The logical alternative is to use adhesives based on synthetic polymers, which offer the additional advantages of longer storage stability and lower consumption. Up to now, however, the products available on the market showed certain limitations when compared directly with casein adhesives.
