Abstract (en)
[origin: WO2007047767A2] An air-packing device has deflation cut slits for tearing the plastic films thereof to remove the air after use. The deflation cut slit is suitable for an air-packing device having a multiplicity of air containers each having a check valve that prevents reverse air flow. The deflation cut slit is provided in a sealing area located between adjacent air containers. The plastic films are bonded at the sealing area so that the deflation cut slit will not leak the air from the air container of the air-packing device. The deflation cut slits are aligned in the same direction to function as perforations to allow a user to cut the air-packing device along the predetermined direction.
