Valdamark have a comprehensive stock of market leading VCI corrosion Inhibitor products.

VCI Bags are perfect for protecting sensitive ferrous metals whether travelling through the supply chain or during storage.


What is VCI Film?

Volatile Corrosion Inhibitor. The Corrosion Inhibitor formula works through a method of polar bonding whereby once your goods are sealed in the enclosed space the molecules create a kind of ‘mini atmosphere’ that attach to the surface of your metal product.

This then protects the goods into the long term from the all the usual corrosion culprits. Including Air, Water, Dust, Acids and perspiration.

Corrosion Inhibitors are available in differing formats and deliveries. Low Density Polyethylene (LDPE) based flexible packaging with ‘built in’ VCI is the most popular choice, particularly for goods that are to be transported, exported or stored for an extended period of time.

VCI Film has some key advantages in that the LDPE plastic does provide a low to moderate moisture barrier. In addition to corrosion inhibitor protection it is also very easy to use and provides better protection from environmental contaminants like dust and polluted air.

Like all VCI products film offers additional benefits in that parts do not need to pre treated or cleansed of oil and wax with degreasers or solvents. This ‘value equation’ can result in significant cost savings for the user.

It is also fully recyclable, safe and non-toxic to whoever is handling it.

How does VCI Paper work?

In much the same way as the corrosion protection film. The paper is essentially the carrier for the corrosion inhibitors.

It can be said that the corrosion inhibitors tends to emit & migrate more quickly from paper as opposed to film. This is perfect for humid conditions where the aggressive environment will accelerate the chemical reaction for corrosion to occur.

VCI Paper mitigates this somewhat.

What is the difference between VCI and VpCI?

VPCI® is patented Cortec® technology. VPCI or Vapour Phase Corrosion Inhibitors utilize a mechanism of action that can be considered superior to commodity VCI plastic bags.


VPCI Corrosion Inhibitors migrate and bind onto the nearby metal surfaces to  form a thin molecular layer that protects goods from rust and corrosion well into the future.

Vapour Phase Corrosion Inhibitors tend to be a more consistent product in that dosing of the formula itself is done volumetrically for each bag, as it is with the blue LDPE polyethene material.

Unlike cheaper alternatives VPCI keeps working well into the long term. It is trusted by the worlds leading manufacturing brands as one of the best corrosion prevention methods available.

In addition there are many supplementary products that can be used for an optimal solution or as a standalone measure.

We stock a wide range of anti corrosion spray formulas that can be used either by themselves for a wide variety of corrosion protection work or sprayed/misted onto metal goods before they are sealed inside flexible packaging.
