Vapor Corrosion Inhibitor Paper products from Cortec are unique in their ability to provide ‘best in class’ corrosion protection for a wide variety of metals.
VPCI 149 has been specifically formulated to give enhanced protection to sensitive metals such as copper, aluminium and cast iron.
VPCI 149® has a diverse range of applications and can be used as an effective solution for a variety of packaging needs. The paper itself has a unique feel, as it uses a neutral & natural kraft paper the coating is such that whilst the paper has a ‘soft’ feel it wraps very easily around metal parts. This makes VPCI 149 extremely easy to use.
Furthermore, as this construction does not use saturated paper like cheaper alternatives it maintains a remarkably high tear resistance.
This specification utilises the renowned vapour phase corrosion inhibitor technology that results in a far superior level of protection to legacy VCI Paper alternatives.
These VPCI corrosion inhibitor molecules provide strong vapour phase protection that makes this an effective solution for protecting void & cavity spaces as well as being good at interleaving.
VPCI 149 paper is made from the highest quality neutral and natural Kraft paper. Both chlorine and bleach free there is no risk of the usual ‘contamination culprits’ found with other VCI paper roll products.
There are no additional chemical concentrations that need to be calculated with VPCI 149. Simply wrap your products in the paper and fold the edges together.
Consider using adhesive tape (or even a heat sealer) to position and seal the Vapor Corrosion Inhibitor Paper in place.
The VPCI inhibitor molecules then evaporate onto the surrounding metal surfaces to offer complete corrosion protection.

Frequently Asked Questions
• What exactly is Valdamark Direct VCI Paper and how does it work to prevent rust?
Valdamark Direct VCI Paper is a specially treated kraft paper that has been infused with a unique blend of Vapor Corrosion Inhibitors. When you use it to wrap or interleave metal items, these VCI molecules actually vaporise and create an invisible, protective atmosphere around the metal surface. This molecular layer then acts as a barrier, preventing oxygen, moisture, and other corrosive elements from reacting with the metal and causing rust or corrosion. It’s like creating a microscopic shield for your valuable parts!
• Is VCI paper a "one-size-fits-all" solution for all metals, or are there different types for specific materials?
Valdamark Direct offers VCI paper designed for a wide range of metals. While many of our VCI papers are formulated to protect both ferrous (like iron and steel) and non-ferrous metals (such as aluminium, copper, and brass), we also have specialised options if you're dealing with particular alloys or need extra specific protection. It’s always worth checking the product details to ensure the best compatibility for your project.
• What's the main difference between Valdamark Direct VCI Paper and traditional rust prevention methods like oils or greases?
The biggest difference is how clean and easy VCI paper is to use. Unlike messy oils and greases, which require application and then often a thorough cleaning before use, Valdamark Direct VCI Paper leaves no residue. Your metal parts come out of the packaging dry and ready for immediate assembly or use, saving you significant time and labour.
• Can Valdamark Direct VCI Paper provide protection for items that are stored long-term, or is it more for short-term transit?
Valdamark Direct VCI Paper is designed for both! It offers excellent protection during transit, safeguarding your components against the elements encountered during shipping. Crucially, it also provides robust, long-term corrosion protection for items in storage, often lasting for years when properly applied in a sealed environment.
• Is the VCI protective layer visible on the metal surface once the paper is removed?
No, not at all! The VCI molecules form a monomolecular layer on the metal surface, meaning it's incredibly thin and completely invisible to the naked eye. Your parts will look exactly as they did before being packaged, with no discolouration or residue.
Relevant products you may want to consider:
• Does Valdamark Direct VCI Paper have any smell or odour that could be undesirable for certain applications?
Generally, Valdamark Direct VCI Paper has a very minimal, if any, discernible odour. It's designed to be clean and unobtrusive, making it suitable for a wide array of applications where strong smells would be an issue.
• What's the best way to wrap smaller metal components with Valdamark Direct VCI Paper for optimal protection?
For smaller components, the key is to ensure the VCI paper is as close to the metal surface as possible and that the package is sealed well. You can simply wrap the item like a present, making sure there's an overlap to create an enclosed VCI atmosphere. Using adhesive tape to secure the folds will help maintain this protective environment.
• How should I use Valdamark Direct VCI Paper as an interleaving material for stacked metal parts?
When stacking multiple metal parts, place a sheet of Valdamark Direct VCI Paper between each layer. This ensures that the VCI molecules can effectively reach all surfaces, even those in direct contact with other parts, providing uniform corrosion protection throughout the stack.
• Is it important to clean metal parts before wrapping them in Valdamark Direct VCI Paper?
Yes, for the best results, it's highly recommended to ensure your metal parts are clean and dry before packaging them with Valdamark Direct VCI Paper. Any existing contaminants like dirt, grease, or rust could hinder the VCI molecules from effectively forming their protective layer.
• How close does the Valdamark Direct VCI Paper need to be to the metal surface for it to work effectively?
To achieve maximum efficiency, the metal product should ideally be no more than 300mm (approximately 12 inches) away from the VCI paper. The closer the paper is to the metal surface, the more concentrated and effective the VCI atmosphere will be.
Relevant products you may want to consider:
• Can I use Valdamark Direct VCI Paper inside a sealed container, like a box or crate, for added protection?
Absolutely! In fact, using Valdamark Direct VCI Paper within a sealed container, such as a corrugated box or wooden crate, is highly recommended. This creates an enclosed space that helps to concentrate the VCI vapour, significantly enhancing the protection for your metal components.
• Are there any special handling precautions I should take when using Valdamark Direct VCI Paper?
It's always a good idea to handle VCI paper with clean, dry hands to prevent any contamination. While the product is generally safe to use, maintaining cleanliness ensures its optimal performance.
• What if I need to temporarily open a VCI-protected package for inspection? Does it compromise the protection?
Good news! Valdamark Direct VCI packaging is quite forgiving. You can generally open and reseal packages for brief inspections without significantly compromising the corrosion protection, as the VCI atmosphere will regenerate once the package is sealed again. Just try to minimise the time it's open.
• Can Valdamark Direct VCI Paper be used with other VCI products, like VCI films or emitters, for enhanced protection?
Yes, definitely! For highly critical applications, very large enclosures, or extended protection periods, combining Valdamark Direct VCI Paper with other VCI products like VCI films, bags, or diffusers can create a more comprehensive and robust corrosion-inhibiting environment.
