  • Patent number: 8409679
    Abstract: A non-foil packaging laminate for liquid food packaging comprises a core layer of paper or paperboard, outermost liquid tight, heat sealable layers of polyolefin and, applied onto the inner side of the layer of paper or paperboard, an oxygen gas barrier layer formed by liquid film coating of a liquid gas barrier composition and subsequent drying, the liquid composition containing a polymer binder dispersed or dissolved in a liquid medium. The laminate further comprises a layer of a polyolefin-based matrix polymer with inorganic filler particles distributed therein and inorganic particles dispersed also in the gas barrier layer from the liquid gas barrier composition. Also disclosed is a method for manufacturing the packaging laminate and a packaging container made from the packaging laminate.

  • Patent number: 8268915
    Abstract: The present invention relates to a liquid mixture comprising a first polymer, which is a poly(acid), a second polymer, which is a poly(ether), and at least one salt, wherein the molecular weight of the poly(acid) is in the range of 1000-100,000 Da. The second polymer is selected to be capable of forming immiscible aqueous phases in the presence of the poly(acid) and salt. The poly(acid) may be selected from the group consisting of poly(acrylic acid) and poly(methacrylic acid), and the second synthetic polymer may comprise ethylene oxide. The invention may be used for separation of biomolecules, cells or particles.
