A recently granted patent (Publication Number: US11858163B2) discloses a method and apparatus for making a shrink label for covering a receptacle from a strip of flexible tubular material. The method involves puncturing the shrink label or the strip to form a puncture spaced apart from the ends of the label, cutting the strip at an open region to separate the label, and then moving the label apart from the rest of the strip before puncturing. Additionally, the method includes providing at least one perforation line in the shrink label, along with the puncture, for added functionality.

Furthermore, the patent claims describe various aspects of the method and apparatus, such as the puncture being performed on a flat region of the label or strip, the inclusion of peripheral and longitudinal perforation lines, and the configuration of the puncture with a central slit and end perforations. The apparatus includes a puncturing means, an opening device for separating inner peripheral portions of the strip, a cutting means for separating the label from the strip, and a perforation means for forming additional perforation lines. These innovations aim to improve the efficiency and functionality of shrink labels for covering receptacles, offering a novel approach to label manufacturing in the packaging industry.
