The raw materials of rust proof woven VCI paper(VCI+) is made of VCI base paper , woven cloth composite with HDPE/PE plastic film, self-developed vapor phase corrosion inhibitor. In the confined packaging space , a certain amount of gas phase corrosion inhibitor can form a uniform and stable anti-rust protective layer in the package, which can effectively inhibit the corrosion of metal products. Poly woven VCI paper(VCI+) has the characteristic of waterproof, moistureproof, puncture resistant.
