The main reason is the function of air column bag, because the middle layer of air column packing is full of air, so light, flexible, with sound insulation, shock, anti-wear performance, it is waterproof, Moisture, compression.
Long time storage and transportation without leakage of the earthquake protection, air column full coverage of the buffer protection, the damage rate to a minimum. Compared with the traditional filler, will not be due to the packaging of large gaps in the box, and in the process of transport items often caused by damage, even if the external squeeze, AIR-BAG personal design can also use air to disperse the pressure to avoid damage.
