<p>An oxygen absorbent package used for preservation or storage of foodstuff containing large amounts of water, alcohols or oils is partly or wholly formed with an air-permeable sheet (10) obtained by making a sheet from thermo plastic fibres by a papermaking process, drying the sheet, impregnating it with a fluorine resin and pressing the resin-impregnated sheet by heated rolls. The obtained package is proof against water and oils. Use of the air-permeable sheet (10) in various combinations with a woven reinforcing material (50), a porous low softening point resin layer (22), a composite 2-layer film (40) and a porous composite film (42) provides a package with improved properties, e.g. heat resistant. The oxygen absorbent package may be used for storage of a packed foodstuff which is heated for long-time preservation.</p> |
