摘要：
A label essentially comprises a top layer which can be printed and/or inscribed and a water-soluble adhesive layer. The adhesive layer can also be protected by a covering layer. The top layer is formed from polyvinyl alcohol which is preferably insoluble in cold water but soluble in hot water. The adhesive layer comprises a synthetic adhesive which is soluble in water and represents, in particular, a contact adhesive or permanent adhesive. The label is resistant to the action of cold water but is soluble in hot water, and is suitable for labeling containers with a smooth surface.
