Gas column bags, also known as buffer column bags, inflatable bags, bubble column bags, columnar inflatable bags, is a new type of packaging material filled with natural air in the 21st century. The comprehensive coverage of the air column buffer protection, the product transport loss rate to a minimum. Air packaging bags, using LLDPE and NYLON bonding or co-extrusion methods, have tensile and equilibrium characteristics, good surface printing, belong to medical-grade substrates, through continuous compression, forming breathless inflatable columns, The machine makes the protective film into a column protection bag called Air Bag. Using physical principles, once inflated, full row filled, automatically locked, formed a diving cabin, encountered damage, only the damaged single column part failed, the rest of the column, completely unaffected, still maintain the protection effect. It provides seismic protection for long-term storage and transportation, and the buffer protection of the ga
