Provided is an air-filling type packaging material. The air-filling type packaging material includes a plurality of air-cells, an air passage, a communication passage, and a sealing member. The plurality of air-cells are divided by adhesion of an upper sheet and a lower sheet and performing a shock-absorbing function. The air passage is formed by adhesion of an upper sheet and a lower sheet such that external air flows into the air-cell. The communication passage is formed by adhesion of the upper and lower sheets, and connected to the air passage at one side thereof and connected to the air-cell to discharge air at the other side thereof. The sealing member is disposed in the communication passage between a portion thereof connected to an air passage and a portion thereof connected to the air-cell to prevent air filled in the air-cell from flowing backward.
