The base material is LDPE, which is low-density polyethylene, the VCI masterbatch added in the film blowing process, as well as color masterbatch, additives, etc.

Among them, VCI masterbatch is a vapor phase anti-rust masterbatch with anti-rust effect, mainly relying on its volatilization to protect the metal surface.

1. VCI is a gas bai phase corrosion inhibitor in the whole process, and the thin du film of gas phase rust prevention is VCI film. In fact, its composition is very simple. The film blown after mixing different dao polyethylene resins and VCI corrosion inhibitors is the finished product. . In anti-rust packaging, VCI film has the best utilization and utilization rate, and the effect is also very obvious. It is used in automobiles, equipment manufacturing, storage and transportation, especially shipping.

2. Although the composition of VCI film is relatively simple and easy to understand, there are actually two key points that determine the performance of the product. One is the composition of VCI and resin, and the other is the mixing and blowing process. If these two aspects are compounded And if the treatment is not good, the resulting film will have poor barrier properties, insignificant anti-rust effect, and poor transparency..
