  • Publication number: 20140050934
    Abstract: A barrier packaging material containing a composite which comprises i) a cellulosic layer; ii) at least one metal layer which will dissolve under alkaline conditions; and iii) at least one polymer layer, in which the polymer is hydrolysable under alkaline conditions. The invention also relates to articles comprising the barrier packaging material. Further, the invention concerns the use of a polymer, which is hydrolysable under alkaline conditions, as a protective layer in barrier packaging products. In addition the present application is also concerned with a method for recycling the aforementioned barrier packaging products. Specifically the barrier packaging products are initially taken in an aqueous wastepaper suspension which is either pulped in an alkaline medium and/or treated in an alkaline medium in a deinking process and in which the metal and polymer are then separated from the cellulosic fibres contained in the cellulosic layer.
