Pressure resistance and airtightness are very good. In the process of transport, often handling goods, ordinary boxes may not be able to withstand the extrusion, easy to leakage and pollution, so the hardness of the box and the high airtight performance in the transport process seems to be crucial, a regular large size UN box, sealing a grown man to stand on the top will not be deformed, it can be very good protection of the goods.
