PURPOSE:To maintain the quality of the photographic sensitive material by using inexpensive materials and to eliminate the uncomfortable feel to a user at the time of unpacking the material by constituting the above material of a laminated packaging material formed by combining special flexible materials. CONSTITUTION:Moistureproof and oxygen shieldable flexible sheets 4, 5 having <50cc/m<2>.24 hour atm oxygen permeability and <=10g/m<2>.24 hour water vapor transmission rate are laminated on one face of a deodorant flexible sheet 10 contg. a deodorant and an oxygen permeable flexible sheet 6a having >=50cc/m<2>.24 hours atm oxygen permeability is laminated on the other face. The malodors generated in the bag and the materials exerting adverse influence upon the photographic sensitive material are, therefore, adsorbed and no adverse influence is exerted on the photographic characteristics while abrupt heat generation and the sticking of the deodorant to the photographic sensitive material are prevented. The uncomfortable feel is not given to the user in this way and in addition, the perfect moistureproofness, and gas barrier and light shielding properties are assured. |
