Abstract
The 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.
