VCI plastic film is composed of vapor phase corrosion inhibitor, polyethylene, processing aids, and functional additives, which is a homogeneous mixture.
According to different objects of metal protection, VCIF can be divided into three categories: steel use, multi-metal use, and special use.
Steel vapor anti-rust plastic film is specially used for ferrous metal anti-rust packaging. Such as cold-rolled steel plate, cast iron, steel parts, and steel hardware tools, etc.
In addition to excellent protection of steel, multi-metal vapor phase anticorrosive plastic film can also protect commonly used non-ferrous metals, including copper, brass and other copper alloys, aluminum and aluminum alloys, silicon steel plates, galvanized sheets, tinned sheets, and other coatings.
Laminate has a good anti-rust effect; The special VCI plastic film is specially used to protect metal product materials, such as copper and copper alloys, galvanized sheets, etc.

VCI plastic film has a wide range of applications. It can be used for any form of anti-rust sealing and packaging of metal products.
The product can meet the packaging of metal products of different specifications, as small as a few millimeters of mechanical parts, as large as the entire aircraft can be packaged.
Applicable fields include the automotive industry, shipbuilding, aircraft, machinery, electrical appliances, electronics, metallurgy, hardware tools, weaponry, and other metal processing fields.
Quality and standard of VCI plastic film:
After comparing the anti-rust performance of various VCIFs, domestic steel membranes are better than foreign ones. The role of the multi-metal film is similar. And the appearance quality of the product is worse than foreign ones in some aspects.
The quality standard of VCI plastic film:
my country already has a national standard for VCI plastic film: GB/T19532-2004 “VCI Plastic Film for Packaging Materials”. In addition to the US military specification MIL-PRF-22019D, other countries have not yet reported.
The formulation of our national standards is based on US military regulations. Although it is “modified and adopted”, the overall level is not lower than the US military’s specifications. The formulation of national standards combined with my country’s actual conditions, so that its scientific, applicability, and operability reached the international advanced level in the late 1990s.
It should be noted that:
Technical index
In addition to adopting all 15 indicators of the US military specifications, GB/T19532 also adds an “alternating damp heat test” and “vapor phase anti-rust test” as needed.
