US 10,943,513 B2 · Fixing wrap-around labels with LED-curable adhesives

Abstract

Provided herewith are methods of preparing a labeled article comprising curing an LED-curable adhesive on a film label such as a shrink film label, wherein at least portions of the LED-curable adhesive are disposed in the overlap formed between a leading edge and trailing edge of the film label. The curing can be conducted at a temperature below 70° C. and is suitable for labeling 500-720 articles per minute in a sequential manner. Also provided herewith are apparatus for labeling articles with film labels, such as shrink film labels comprising an LED station. Further, a method of retrofitting an existing hot-melt labeling system for use in labeling articles with film labels such as shrink film labels is also provided.
