  • GAS PERMEABLE MEMBRANE
    Publication number: 20080202262
    Abstract: A gas permeable membrane comprising a thin polymeric coating on a microporous backing, said gas permeable membrane being permeable permitting for oxygen and carbon dioxide at different flow rates, wherein the gas permeable membrane is made from a copolymer of a polyether and a polyamide enables the achievement of a controlled atmosphere in a cargo region, wherein the membrane is able to obtain and hold low concentrations of carbon dioxide and of oxygen in the atmosphere in the cargo region and to produce an “ideal” or optimum storage atmosphere which will ensure a retardation of respiratory activity within the container.
    Type: Application
    Filed: September 28, 2007
    Publication date: August 28, 2008
    Inventors: Richard Schmidt, Gert Jorgensen, Dorothea Catharina Nymeijer, Hendrikus Henry Maria Rolevink
