Disclosed is a multilayered shrink label with a core layer comprising a continuous phase of a water soluble polymer and a skin layer which are printable and solvent seemable.
Problem and Opportunity
Current shrink labels cannot be removed from bottles in the pre-wash cycle of reclaimers recycling processes. It has been proposed by the industry that perforating the labels along the label parallel to the bottle axis will enable such labels to break off the bottles during the prewash. Tests have shown, however, that such perforations do not help to efficiently remove the labels in those processes.
The subject matter of the present invention solves the current recycling issues with a specifically designed shrink label. The current invention allows the hot water in a pre-wash cycle of reclaimers’ processes to dissolve the specially designed core layer of the film, wherein the core layer forms a bridge between perforations during the process step. Hot water weakens the film bridges sufficiently to enable more efficient tearing along the perforations, which ultimately enables efficient removal of the labels.
