Method for removal of label e.g. paper label shrunk around product packaging e.g. polyethylene terephthalate drink bottle, involves enabling single or multiple splitting of label by using laser beam to remove label from packaging

摘要

The method involves enabling the single or multiple splitting of a label (2) by using a laser beam (11) such that the label is removed from a product packaging (1). The wavelength, power, surface power density and induction period of the laser beam are set to specific values for removing the label from the product packaging. An independent claim is included for device for removal of label shrunk around product packaging.
