OILPROOF DEOXIDIZING AGENT PACKAGING MATERIAL

PROBLEM TO BE SOLVED: To provide an oilproof deoxidizing agent packaging material formed by using a packaging material which causes low environmental load and has practically-sufficient oil resistance by using an oilproof agent in which the carbon number of perfluoroalkyl group is less than 8, and perfluoro octanoic acid, substances similar to that, and precursors thereof are not contained. SOLUTION: The oilproof packaging material is formed by laminating at least three layers in the following order of (A) a thermoplastic resin layer (A) in which upper-surface pores (x) having a diameter of 0.2 to 0.6 mm are formed in advance, (B) oilproof paper () containing the oilproof agent in which the carbon number of the perfluoroalkyl group is less than 8, and (C) a heat-sealing thermoplastic resin layer in which back-surface pores (y) having a diameter of 0.2 to 0.6 mm are formed in advance. The oilproof deoxidizing agent packaging material is formed by packaging a deoxidizing agent (D) while the surface of the heat-sealing thermoplastic resin layer (C) side of the oilproof packaging material is disposed on the inside.
