Abstract (en)
[origin: WO2012163749A2] A description is given of paper or cardboard packaging made from recycled paper with mineral oil contamination, the packaging having a barrier layer which can be produced by applying an aqueous polymer dispersion comprising a copolymer which is preparable by emulsion polymerization of C1 to C4 alkyl (meth)acrylates, acid monomers, such as acrylic acid or methacrylic acid for example, 0-20% by weight of acrylonitrile and 0% to 10% by weight of further monomers, the glass transition temperature of the copolymer being situated in the range from +10 to +45°C. The barrier layer may be located on one of the packaging surfaces, or may form one of a plurality of layers in a multi-layer packaging coating, or may be located as a coating on one side of an inner pouch situated within the packaging.
