With the rapid development of domestic metallurgical manufacturing industry and the introduction of automatic packaging lines, the requirements for packaging efficiency and operators are becoming higher and higher. Based on more than 30 years of industry experience, CVCI has integrated scientific research resources in the industry and developed this product over several years.
Technical principles
Barrier type VCI paper is a kind of paper-plastic composite antirust packaging material, which is composed of VCI, antirust base paper, polyethylene film, plastic woven cloth and barrier film. After the product is packaged, the VCI contained in the paper slowly vaporizes and volatilizes at room temperature to form inhibitor steam, which is adsorbed on the metal surface and forms a molecular protective film, thus playing an excellent role in VCI antirust protection, At the same time, it can also play an excellent contact anti-rust effect when contacting metal. The barrier layer can effectively prevent the external environment water vapor from entering the packaging space, thus reducing the risk of condensation and the risk of moisture corrosion on the metal.
Product features
① Excellent VCI protection and contact antirust performance;
② Excellent barrier performance, the barrier to water vapor is higher than that of ordinary anti-rust paper, and its moisture permeability is equivalent to that of ordinary anti-rust paper plus a layer of plastic film;
③ Excellent physical strength, suitable for heavy metal packaging;
④ The product is safe and environmentally friendly, free of phosphate, chromate and heavy metals, and safe to use, and complies with the requirements of RoHS PFOS PFOA REACH directive of the European Union.
Product application
Barrier type VCI paper can be used for antirust packaging of common cold plate, galvanized plate, tinplate, chrome-plated plate, oriented silicon steel, non-oriented silicon steel, etc. in metallurgical industry, and also for inner core packaging of steel coils.
