Abstract: The present invention relates to a new, adhesively bonded packaging system for foods, more particularly for dairy products.

Abstract: Provided herein is a binder composition for heat-sealable film coatings including from 10 to 65 weight-% of a polymeric binder. The polymeric binder includes, as monomers, keto- or aldehyde containing monomers, monoolefinically unsaturated monomers, and copolymerizable surfactants. The monoolefinically unsaturated monomers contain less than 0.4 weight-% of the monomers with acidic functional groups or amides of acidic functional groups with respect to the total weight of the monomers. The polymeric binder furthermore contains from 2.5 to 100 mole-% dihydrazide crosslinker with respect to the keto- or aldehyde-containing monomers, optionally from 0 to 3.0 weight-% non-reactive surfactant, from 35 to 90 weight-% water, optionally from 0 to 20 weight-% other additives, and optionally from 0 to 20 weight-% humectant. Further provided herein is a process for preparing an aqueous sealing coating that includes applying a binder composition on a heat-sealable film including corona treated polyolefins.

Abstract: Described is paper or cardboard packaging produced from mineral oil contaminated, (e.g., recycled) paper, wherein the packaging includes a barrier layer obtainable by applying an aqueous polymer dispersion comprising a copolymer obtainable by emulsion polymerization of C1-C4 alkyl (meth)acrylates, acid monomers, e.g., acrylic acid or methacrylic acid, 0-20 wt % of acrylonitrile and 0 to 10 wt % of further monomers in an aqueous medium in the presence of a carbohydrate compound, preferably in the form of a degraded starch, wherein the glass transition temperature of the copolymer is in the range from +10 to +45° C. The barrier layer may be situated on one of the surfaces of the packaging or form one of multiple layers of a multilayered packaging coating or be situated as a coating on one side of an inner bag situated within the packaging.
