Abstract

The invention relates to an adhesive system for labeling containers, more especially hollow containers, with wrap-around labels. The adhesive system comprises a pick-up adhesive and an overlap adhesive. It is characterized in that, in the wet state, the pick-up adhesive has sufficient wet bond strength for labeling and, in the dried state, does not adhere to at least one of the substrates. The pickup adhesive contains 5 to 85% by weight and preferably 5 to 60% by weight of at least one water-soluble polymer based on casein, starch, dextrin, glucose, polyvinyl alcohol, polyurethane or polyacrylic acid, 0.00 to 1.00% by weight and preferably 0.01 to 0.30% by weight of at least one defoamer, 0.00 to 1.00% by weight and preferably 0.01 to 0.30% by weight of at least one preservative and water as the balance to 100% by weight.
