Abstract
PURPOSE:To improve the formability, strength, rigidness and gas permeability of partition film and prevent the lowering of the function of a freshness retaining agent by forming the partition film of plastic sheet, providing the partition film with projecting film portions, with the thickness of the latter smaller than that of the former and specifying the oxygen permeability of the partition film. CONSTITUTION:In this example (embodiment), a freshness retaining agent 2 is placed in a space defined by partition film for receiving the same, i.e. by the partition film 1 formed of a gas permeable film and a bottom lid 41 of a container. This gas permeable partition film 1 and the bottom lid 41 of the container are sealed at the bottom of the container 4 by forming crimped portions 411, with their peripheral edges arranged in coincidence. The partition film for receiving freshness retaining agent is provided with a single or plurality of projection film portions, with the thickness of the latter smaller than that of the former. The oxygen permeability of the partition film is held within the range of 1000-30000cc/m<2>.atm.24hr (25 deg.C, 60%RH). As the material of the partition film, the plastic sheet consisting of polypropylene is used, preferably with the thickness within the range of 100mu-2000mu.
