Abstract: A proposal is made for a label (1) which can be adhered to an article (5), more particularly to a beverage bottle, and can be detached again in a washing liquid at a washing temperature of at least 5O° C., in the form of a laminate at least with the following layers: a biaxially stretched polymeric film layer (9) which shrinks at the washing temperature, a printed decoration layer (11), and an adhesive layer (13), more particularly a pressure-sensitive adhesive layer, for adhering the label (1) to the article (5). The polymeric film layer (9) is designed in such a way that in the laminate at the washing temperature within a maximum time span of less than 5 minutes, in particular less than 3 minutes, it attains degrees of contraction in its two stretching directions which differ from one another by less than 50% and are lower than 50%. As a result of this, whereas the adhesive force between the label (1) and the article (5) is high, the label (1) can be washed off from the article (5) without splitting.
