A brief introduction to VCI rust preventive bags
VCI rust preventive bags can also be called vapor phase rust preventive bags. In fact, the rust prevention of VCI rust preventive bags can be described as a gasification reaction. When we use the gasification principle to firmly attach VCI rust preventive particles to the PE film bag and carry out rigorous processing, we can form a VCI rust preventive bag with rust prevention function.
