Principles of rust gas bag is used to prevent the bag from the processing of a special corrosion product packaging bags, mainly used for packaging of precision mechanical products. 

 VCI corrosion inhibitor through the bag in the continuity of play out of gas, attached to the surface of metal objects to be packed, embroidered cavitation damage reflection function to protect against any type of metal object against corrosion. To meet the different users have on the flow of products, export, warehousing and transport links to the rust-proof requirements. Packaging efficiency, the use of tape, stapler and other simple way to seal bags can rust, so rust, packaging automation a reality.
