PAPER/FIBROUS SUBSTRATE AND METAL LAMINATE STRUCTURES HAVING SURFACE COATING CURED BY UV RADIATIONS IN INERT ATMOSPHERE AND POUCHES/SACHETS MADE THEREOF

摘要

The flexible packaging laminate structure includes an outer fibrous layer and an inner metallic layer adhered to each other. The outer fibrous layer comprises a top surface and a bottom surface. The top surface includes at least one of text/images printed with ink, hot foil transferred text/images, or registered or un-registered holography or Fresnel lense. Further, the top surface is coated with UV curable coating and cured using UV radiations in an inert atmosphere respectively. Furthermore, the inner metallic layer is of a metal foil having a first surface and a second surface. The second surface includes at least one sealing lacquer layer employed thereon. In another embodiment, two sealing lacquer layers are disposed on the second surface, i.e. a primary sealing lacquer layer for providing bonding strength to the inner metallic layer of metal foil, and a secondary sealing lacquer layer for enabling sealing of the inner metallic layer of the metal foil to itself.
