FIXING OF WRAPPING LABELS WITH ADHESIVES CURED BY LIGHT-EMITTING DIODES (LEDs) Russian patent published in 2021 - IPC B65C3/16 

FIELD: product labeling.

SUBSTANCE: this document proposes methods for producing a labeled product, including curing an adhesive cured by LED on a film label, such as a heat shrink film label, with at least sections of the adhesive cured by the LED being located on the overlap formed between the front edge and the back edge of the film label. Curing can be carried out at temperatures below 70°С, and it is suitable for sequential marking of 500-720 products per minute. Also in this document, devices for marking products with film labels, such as heat shrink film labels, which contain a LED section, are proposed. In addition, a method for upgrading the existing system for applying labels with a hot-melt adhesive for use in marking products with film labels, such as labels made of heat shrink film, is also proposed.

EFFECT: improving the methods of marking products with the help of heat shrink film labels.
