The anti rust principle of anti rust bags and their differences from ordinary plastic bags

Rust proof bags are made by hot cutting composite processing of rust proof film, and their rust prevention principle is the same as that of rust proof film. Anti rust film is made of VCI Gas phase anti rust masterbatch is mixed with plastic particles and produced through advanced blow molding technology using multi-layer co extrusion technology. In this way, VCI The gas-phase corrosion inhibitor will be evenly distributed on the entire surface of the rust proof film.

After packaging metal parts with rust proof film, they will be placed in a sealed packaging space and adjusted according to changes in environmental temperature and humidity, VCI The gas will continue to evaporate and adsorb onto the metal surface, forming a relatively saturated rust proof and protective environment. VCI Molecules will form at least one molecule thick anti rust protective layer on the metal surface, passivating the metal while blocking the erosion of oxygen and moisture. This is the basic principle of its anti rust.

The difference between rust proof bags and ordinary plastic bags is that:

The main function of rust proof bags is to prevent metal from rusting.

Compared with ordinary plastic bags, rust proof bags not only have the characteristics of good heat sealing performance, good flexibility, and good transparency, but also have the feature of low water permeability.

Ordinary plastic bags only have the basic function of waterproof, moisture-proof, and dust isolation, and do not provide rust protection for metal products.
