VCI-Corrosion Protection Film

What should be taken into account when packaging materials?
Metal surfaces should be clean wherever possible
They should be clear of deposits from previous processes else trials are recommended for compatibility check.
Corrosion should not be already apparent
The packaging should be applied and sealed as tightly as possible (avoid drafts); the more securely sealed the outer packaging, the longer and more secure the corrosion protection.
Printed surface to the outside, because outer surfaces often carry special characteristics
Metals Part should not be in direct contact with wood / corrugated box surface.

These limits can be broken by consulting experts.

Active VCI substances can be integrated in a wide range of carrier materials. For example papers, films or fluids.

VCI means Volatile Corrosion Inhibitor, in other words a volatile prevention of corrosion or anticorrosive. The term VCI inhibitor is understood to mean the working of special volatile linkages into differing carrier materials. Inherent inhibitor vapour pressure causes them to evaporate out of the carrier material and to diffuse within the packaging. They are absorbed onto metal surfaces in the form of an invisible film. Once there, they provide active protection against the breakdown of the passive layer.

The film continually releases small amounts of active substances into the atmosphere inside the packaging, meaning that metal surfaces that are not directly in contact with the film also benefit from protection. The distance between film and the surrounding metal surfaces will depend on the packaging volume and the amount of time needed for a protective atmosphere to build up - 10 cm can be used as a rule of thumb. Depending on the packaging volume, it can take up to 20 hours for a sufficient protective atmosphere to dev
