PROBLEM TO BE SOLVED: To provide an easily-deaerated moistureproof bag quickly deaerated without a leakage of the content when filling the moistureproof bag with the content, and prevented from moisture infiltration, seepage of oil content of the content, etc. after filled and sealed.SOLUTION: An easily-deaerated moistureproof bag includes: an air-permeable inner layer 2; an air-impermeable and liquid-impermeable intermediate layer 4 provided with deaeration slits 3; and an air-permeable outer layer 6 provided inside with an air-impermeable and liquid-impermeable plastic layer 5 to cover the deaeration slits 3 of the intermediate layer 4. Consequently, when a paper bag 1 with a valve is filled with the content by pneumatic transportation, deaeration is performed through the inner layer 2, the clearances of the deaeration slits 3 of the intermediate layer 4, and the outer layer 6, and after the end of pneumatic transportation, the plastic layer 5 is brought into close contact with the deaeration slits 3 of the intermediate layer 4 to prevent moisture infiltration from the outside, seepage of oil content of the content, etc. |
