<p>The three-fold opaque laminate for production of documents, tickets, labels and packing papers, comprises a foil for carrying metal-/color layer and papers or fleeces for allowing uneven shining through the metal layer. The three-fold laminate structure is paper-foil-paper or fleece-foil-paper or fleece-foil-fleece. The foil exhibit a thickness of 12-100 mu m, shows positions on the outside surfaces of the papers or fleeces, have a color deviation delta (E) of 1.0 to the average coloration value measured from 30 randomly distributed measuring points on DIN A4-sheet.

The three-fold laminate structure is paper-foil-paper or fleece-foil-paper or fleece-foil-fleece. The foil exhibit a thickness of 12-100 mu m, shows positions on the outside surfaces of the papers or fleeces, have a color deviation delta (E) of 1.0 to the average coloration value measured from 30 randomly distributed measuring points on DIN A4-sheet. The thin metal layer is applied on the foil by a vacuum evaporation process. The papers or fleeces exhibit a weight per unit area of 10-50 g/m 2> and shows a small total opacity and high fluctuations of the opacity over the surface, and exhibits a coating, which is printable by ink jet-, thermal-, thermal transfer- or laser printer. A varnish has a dye and is applied between the foil and an adhesive. The opacity of the laminate is 99%, measured according to DIN 53146 (ISO 2471). The breaking load of the laminate lies between 40-3000 N/15 mm, measured according to ISO 1924. The adhesive between the metallization and the paper, exhibits an uneven structure, which is visible through the paper.</p> |
