Abstract:
1. A method of making a packaging material, comprising the steps of: providing a substrate comprising at least one sheet of plastic material, the substrate comprising a first side and a second side; printing ink on the first side of the substrate; applying an energy-curable coating to the first side of the substrate over the ink, the energy-curable coating comprising a slip agent; curing the energy-curable coating and reacting-in the slip agent by exposing the energy-curable coating and slip agent to a suitable energy; and applying a cold-seal cohesive coating to at least a portion of the second side of the substrate, the energy-curable coating providing a surface for temporary adhesion of the cold seal cohesive coating to the first side of the substrate when the substrate is stored in a roll, without blocking of the cohesive coating upon removal of the cohesive coating from the energy-curable coating.
