Abstract
The invention relates to a transfer label comprising a backing layer and a transfer layer which is releasably attached to the backing layer. From transfer to a container, the transfer layer is detached from the backing layer. After attachment to a container, the transfer layer can be removed in an aqueous liquid under turbulent soaking conditions at a temperature of not more than 100° C., preferably not more than 70° C. During these conditions, the transfer layer breaks up in at least four parts wherein each part is not smaller than 5 micrometers. The transfer layers is detached from the container with a soaking time of not more than 20 minutes, preferably not more than 10 seconds. The transfer label according to the present invention has a very high adherence during storage and use conditions, and can be rapidly removed from a container such as a reusable crate for bottles, in an economic manner.
