ABSTRACT:
A packaging material, a method of making such a material, and a package made from such material, are disclosed. A substrate comprises at least one sheet of plastic material. An energy-curable coating is applied to one side of the substrate, which will be the outside of the eventual package. The energy-curable coating is cured by exposing it to an electron beam or other appropriate energy. A cold-seal cohesive coating is applied to the other side of the substrate. The package is formed by pressing together portions of the inside surface of at least one sheet of the material having the cold-seal cohesive coating on them to form a seal. Preferably, the cold-seal cohesive coating is applied only to those portions of the material that are to form seams in the eventual package.
