  • Oxygen generating materials, carbon dioxide absorbing materials, and transport system and transport method of live fishery products
    Patent number: 6612259
    Abstract: The present invention provides an effective oxygen generating materials, carbon dioxide absorbing materials, and transport system and transport method of live fishery products for use upon transporting live fishery products. An oxygen generating materials of the present invention is prepared by packaging solid peroxide and peroxide decomposition catalyst with a moisture-permeable material having a cup method moisture permeability (40° C., 90% RH) of more than 20 g/m2/24 hr and being impervious to water at normal pressure. Furthermore, a carbon dioxide absorbing materials are prepared by packaging alkaline earth metal hydroxide and/or oxide with a gas-permeable material having a Gurley method gas permeability (JIS P8117) of 0.1˜3000 sec./100 ml of gas and being impervious to water at normal pressure.
    Type: Grant
