<p>PCT No. PCT/FI93/00060 Sec. 371 Date Aug. 12, 1994 Sec. 102(e) Date Aug. 12, 1994 PCT Filed Feb. 19, 1993 PCT Pub. No. WO93/16877 PCT Pub. Date Sep. 2, 1993The invention concerns laminates incorporating plastic layers and cellulose fiber layers and a method for the production thereof. The plastic layers and the cellulose fiber layers incorporated in the laminates can be separated intact from each other in aqueous defibering by virtue of a water-soluble polymer layer placed adjacent to the fibrous layer whereby all components of the laminate become recyclable for reuse. The laminates can be produced using extrusion coating/laminating methods. The laminates according to the invention are suited to use as, e.g., wrapper and packaging materials.</p> |
