Abstract: A permeable film or container for use in extending the storage life of a foodstuff or produce is provided. The film or container is formed from a plastics component, a porous component having a particle size smaller than the thickness of the film, and an acid component selected from at least one carboxylic acid compound in free or salt form. The permeable film is adapted for controlling the environment surrounding the foodstuff to reduce its respiration rate or senescence by controlling the transfer of gases, particularly oxygen and carbon dioxide, and build up of moisture. In one preferred embodiment the present invention provides a permeable film for use in the storage of a foodstuff, formed from a polymer component, a clay activated base component, and sorbic acid in free or salt form.

Abstract: A permeable film, sheet or package for use in extending the storage life of a foodstuff or produce is provided. The film, sheet or package is formed from a plastics component, a porous component having a particle size generally smaller than the thickness of the film, sheet or package, and an acid component selected from at least one carboxylic acid compound in free or salt form. The permeable package is adapted for controlling the environment surrounding the foodstuff to manage its turgidity or senescence by managing the transfer of gases, particularly oxygen and carbon dioxide, and build up of moisture. In one preferred embodiment the present invention provides a permeable film for use in the storage of a foodstuff, formed from a polymer component, an activated clay component, and sorbic acid in free or salt form.
