2130444 9316877 PCTABS00025 The invention concerns laminates incorporating plastic layers (3, 3') and cellulose fibre layers (2) and a method for the production thereof. The plastic layers (3, 3') and the cellulose fibre layers (2) incorporated in the laminates can be separated intact from each other in aqueous defibering by virtue of a water-soluble polymer layer (1) placed adjacent to the fibrous layer (2), 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.
