The present invention relates to a laminated foil, the raw materials of which can be separated and recovered. The bond (14) between the layers (12, 16) of the laminate keeps the layers together when no external force is exerted on the layers, but allows the layers to be separated from each other either by hand or mechanically. Bondless edges (22) have been formed on the foil, i.e. the bonding material has been removed from the edge in order to facilitate the separation of the layers. A foil like this can be cut into blanks to be used as wrappings in packing. Preferably the bondless edges are formed at the packing machine. Thereby it is easy for the consumer to get a hold of the pre-separated edges (32) of the layers and to separate the layers from each other by pulling them apart by hand. |
