Title: HEAT SEALABLE PACKAGING MATERIAL COMPRISING MICROFIBRILLATED CELLULOSE AND PRODUCTS MADE THEREFROM
Abstract:
The present invention is directed to a packaging material comprising a layer of microfibrillated cellulose (MFC) and an aluminium layer having a thickness of 0.1-20 µm, wherein the layer comprising MFC and/or the aluminium layer has been laminated or extrusion coated on at least one side with a thermoplastic polymer and wherein the amount of aluminium is sufficient to make the packaging material heat sealable by induction. The MFC layer contains at least 60% by weight of microfibrillated cellulose.
