20100215925 | PRINTED THERMOPLASTIC FILM HAVING A PVB INK LAYER AND A RADIATION-CURED OVERPRINT COATING - A printed thermoplastic film having a radiation-curable overprint coating is disclosed. The thermoplastic film is printed with an ink system that comprises a polyvinyl butyral carrier resin, a pigment dispersed in the carrier resin, a solvent, a plasticizer, and a coupling agent. The polyvinyl butyral based ink system provides better adhesion to the thermoplastic film than conventional nitrocellulose-based inks when used in conjunction with the radiation-curable overprint coating. | 08-26-2010 |
20110049002 | FILM FOR THERMAL ADHESION TO A RIGID BIOPOLYMER STRUCTURE - A film formed from biopolymer lamination for thermal lamination to a rigid biopolymer structure including a polymer layer; a biopolymer layer; and an adhesive layer joining the polymer layer to the biopolymer layer. The biopolymer layer is thermally adherable to the rigid biopolymer structure. | 03-03-2011 |
20110171461 | HIGH BARRIER FILM - A high barrier film and method of forming a high barrier film. The film includes a biopolymer and metallization layers. A primer layer is applied to one of the metallization layer and the biopolymer layer and a nanocomposite barrier coating is disposed between the primer layer and the metallization layer. The film includes a second biopolymer layer and an adhesive layer, the adhesive layer disposed between the second biopolymer layer and the metallization layer, where the second biopolymer layer is adhered to at least one of the biopolymer layer, the metallization layer, the primer layer and the nanocomposite layer. | 07-14-2011 |
