A wrap-around labeler is a machine used in the packaging industry to apply labels to round or cylindrical products such as bottles, jars, or cans. The labeler consists of a conveyor system that moves the product through the labeling process and a labeling head that applies the label.The labeling head applies the label by wrapping it around the product as it moves through the labeling station. The label is dispensed from a roll and is held in place by a backing paper or a pressure-sensitive adhesive.
