Labeling innovation for beverage bottles
Labels have to stick securely to glass bottles under the most adverse conditions, for example when a chilled bottle is also wet. Nevertheless, the label has to be easily detachable when the bottle is being cleaned. Henkel Adhesive Technologies has developed a new polymer for its glass bottle labeling adhesives that not only delivers outstanding performance features but is also casein-free. Casein, which is commonly used to manufacture labeling adhesives, is a protein contained in cow’s milk and is subject to high volatility in availability and price.
The new Aquence XP generation of labeling adhesives for multi-use bottles is based on synthetic materials. The multinational AB InBev brewery group uses this water-based solution on the production line for its famous Beck’s brand at the Bremen site in Germany. The novel series of casein-free adhesives reduces the material usage, makes the process more efficient and enables Beck’s to apply all the labels and film/foil materials in its factory with just one adhesive.
The new formulation with its synthetic polymer component is an effective solution that offers the following advantages:
- Optimal adhesion even under difficult conditions and easy wash-off in the bottle cleaning bath
- Reduced material usage and improved process efficiency
- Complete independence from the price and volume volatility of casein
- Enables Beck’s to process all its labels and film/foil materials using just one adhesive
