<p>PURPOSE:To obtain a deoxygenating agent-housing bag which is easy to control air- tightness and becomes gas permeable when being used by providing a filter medium having a gas permeability and a hot adhesiveness between wrapping materials having a hot adhesiveness and by forming vents openable by cutting in the adhered portion. CONSTITUTION:A pair of the heat seal bars 7 and 8 are applied on the wrapping material 1 and a bag is formed by the adhering portion ld formed on the bottom portion and the adhering portion 1a formed on the side portion. Then a deoxygenating agent from the charging hopper 18 is filled into a bag, and as the bag moves downwards, the outside of the wrapping material is pushed by the heat seal bars 19 and 20 so as to form the adhered portion 1c, enclosing the bag. A train of plural deoxygenating agent-housed bags so formed are separated into sets of two bags by cutter. Thus, when being used, the gas vents are opened by cutting the adhered portion and the deoxygenating agent in bag is brought into contact with the air through the gas vents and vacant room, so that its gas permeability can be exhibited only when being used.</p> |
