Abstract
A sleeve label having an open top and bottom for sleeving a product such as a bottle, jug, or drum. The sleeve label comprises a plastic film printed on one surface with a solvent base ink. The printed surface is coated with a UV curable coating, covering the printed side including the solvent base ink. Upon curing with UV energy, the coating protects the ink from smearing in contact with solvents. The coating also protects the ink from mechanical damage such as scratching or abrasion. The UV curable coating may be applied to the film with a flexographic print station, or other roll or blade coaters. The coating may be of the free radical acrylate or cationic epoxy types.
