Published August 13, 2010VCI paper is coated with rust inhibiting chemicals. These chemicals vaporize into the air around the metal parts protecting them from rust and corrosion. VCI paper used in shipping metal parts eradicates the need for airtight packages.
Look for environmentally safe VCI paper approved by the US military.
With all those chemicals vaporizing, is VCI paper healthy for the environment? Not all VCI papers are alike in this respect.When purchasing rust inhibiting VCI paper, make sure to enquire whether the papers are environmentally safe, fully recyclable and repulpable, biodegradable and non-toxic. Some VCI Paper contain nitrites or heavy metals, and can harm the environment. In addition, not all VCI papers are approved on the prestigious Qualified Product List (QPL) for Military specification MIL-PRF-3420, an approval that dates back to 1983. When choosing VCI paper, it is important to check to ensure that the paper is approved on this list.
Choose the Right Paper for your Metal.
Different types of VCI papers are specifically manufactured to provide the best rust protection for each particular metal. There are VCI papers designed specifically for different types of metals, and for length of time to be protected.There are huge differences in metal composition and one VCI paper does not meet all metal protection needs for every metal. You can use a rust inhibitor paper or an anti rust paper.A knowledgeable sales person can tell you exactly how much VCI is contained in each paper type, and which will keep your products corrosion free for years.
For instance, VCI Paper for ferrous metals is designed to protect steel parts and wires, die casting, springs, bearings, and stampings.VCI Paper for non-ferrous metals is designed to protect non-ferrous metals. VCI multi-metal papers prevent corrosion on non-ferrous metals and multi-metal products like zinc, aluminum alloys, copper alloys and dissimilar metal components such as circuit boards.
Choose a VCI Paper Coated on Both Sides.
Make sure the VCI papers you purchase are impregnated with VCI on both sides. This avoids confusion about which side to place against the part when packing, as well as the ability to interleave the paper within a pallet of parts so that less paper is required in the packaging.

VCI Poly Bags, also known as Volatile Corrosion Inhibitors, provide effective and long lasting protection against rust and corrosion to metal parts, components, assemblies, forgings, castings, metal stampings, powdered metal parts automotive parts, and all other metal products made out of ferrous, non-ferrous metal and multi metals. Metals protected include carbon steel, chrome, stainless steel, copper, brass, aluminum, silver, silicon steel, galvanized steel; while in-process, during storage, and throughout the shipping cycle while in transit and overseas shipment for exports.
Causes of Corrosion
Surfaces of most of the metals rust and corrode due to moisture, water, acids, salts and other contaminants that are always present in our atmosphere. Corrosion and deterioration of metal surfaces also take place when they are exposed to gases containing sulfur, acid vapors and ammonia gas. Common culprits include by-products of the manufacturing process, by-products from heat treating, and fork truck exhaust.
The corrosion process is often accelerated when metal products are exposed to environmental changes such as fluctuations in temperature and humidity which often happens during product transportation, overseas shipments or long term storage.
Anti Corrosion Packaging, Green VCI Poly Bags, VCI Poly Tubing & VCI Poly Sheets
Green VCI Poly Products are available in several forms: Flat VCI Bags, Gusseted VCI Bags, VCI Poly Tubing, VCI Poly Sheeting, VCI Bubble Bags, and VCI Stretch Film. One of the most popular VCI products is Custom-Sized Gusseted VCI Poly Bags. All of these VCI Poly Products provide the most effective packaging solutions for protection against rust and corrosion for both ferrous, non-ferrous metals and also multi metal surfaces, electronic components, parts assemblies and finished goods.
Advantages of VCI Poly Products
Green VCI Poly products provide excellent long-term protection against rust and corrosion for all metal parts and components. Parts protected with Green VCI Poly will stay corrosion-free for 5 years or longer. Green VCI Poly gives the added protection of a moisture barrier, and they are also excellent dust and contaminant barriers. VCI Poly products are naturally grease and oil resistant. Because they are transparent, products can be inspected without the need of removing the parts from the packaging.
Another advantage of Green VCI Poly bags is their ease of use. Simply place your parts in a Green VCI Poly Bag. There is no need for spraying, dipping or brushing on oils or greases. Parts stay corrosion-free and customers receive parts that are dry with no need to remove oils. Green VCI Poly products are much more environmentally-friendly than traditional rust preventative oils and greases.
Published March 19, 2010VCI Packaging is a must for many manufacturers because it helps keep metal parts rust free during the shipping process. Environmentally friendly VCI packaging paper and poly products can save manufacturers significant amounts in returns and replacements.
An upcoming conference on corrosion protection illustrates just how important rust prevention really is. The COROSAVE 2010 International Trade Fair for Corrosion Protection, Preservation and Packaging will be held in the Exhibition Centre Stuttgart, from October 12 to the 14th 2010. The conference illustrates how important corrosion protection really is, not only to metal foundries, but also to all manufacturers. A press release about the conference points out that corroded parts can lead to waste, subsequent processes being impaired, or component failure. Corrosion is responsible for production damage in automobile electronic parts, computer parts, mobile phones and more. During production, storage, or shipping corrosion protection is equally important. Corrosion inhibiting packaging can guarantee that metal components meet required levels of purity before assembly or further processing.
Corrosion is a result of oxidation, moisture or destructive elements coming in contact with the metal surface. Many materials that protect against corrosion such as oil, grease or paint are harmful to the environment and costly to apply. VCI (Vapor Corrosion Inhibitor) technology works on a molecular level to protect metal surfaces against corrosion and oxidation.
VCI works by creating an invisible molecular protection layer on metal surfaces. The corrosion inhibitor evaporates out of the packaging products (including film, foam, paper, tablets etc), which are used to seal the metal in a closed environment. This environment is subsequently saturated with the corrosion inhibitor and a thin molecular protection layer adheres to all metal surfaces. Combining the sealed package and the VCI technology works to prevent corrosion.
Metal parts come in many different shapes, weights and sizes. For this reason VCI packaging technology is available in different forms such as film, foam, paper, emitters, powders, and liquids.
VCI Packaging Film:
VCI corrosion protection film can be used in bags, covers, and simply as film. Film VCI packaging can be used to pack large machines, pallets, and bulky parts that need to be wrapped for protection. Film can also be used to package large machines for transport.
VCI Packaging Foam:
VCI corrosion protection foam comes is various sized pieces and can be added to non-corrosion protected packaging. It is especially useful when placed inside electrical cabinets, boxes, crates, or hermetic packages. Combining VCI packaging film and foam enables faster saturation of the corrosion inhibitor so that high-tech components are quickly protected from corrosion.
VCI Packaging Paper:
VCI paper can be used to wrap metal parts, especially if they are placed in metal boxes. Sheets of VCI paper can be placed inside wooden crates or boxes.
VCI Packaging Emitters, Powders, Tablets and Liquids:
VCI emitters can be used in closed cabinets to protect electrical parts. VCI powder can be added to a closed system, especially water systems. VCI tablets can be placed in small packages. VCI liquids are also available for coating metal parts.
Methods of VCI packaging can be combined to provide the longest and most effective degree of protection metal parts manufacturers need. Consult a VCI packaging specialist to ensure that metal parts are adequately protected from environmental factors like salt, moisture, air, temperature, and other elements.
It is very important to package metal materials immediately when they are manufactured because after they are corroded no VCI packaging material can repair them.
Published March 1, 2010One of the biggest reasons why metal parts become rusted is because of improper handling of those parts while they are in your plant. Metal parts should never be left exposed to the air in your plant. Contaminants in the air, fork truck exhaust, and by-products of your manufacturing process can all contribute to accelerating rust and corrosion.
WE’VE GOT YOU COVERED
Metal parts that are in-process or waiting for secondary operations should be covered with VCI paper or placed in a VCI bag for corrosion protection. By keeping your parts protected with VCI, you will prevent the contaminants in the air, and corrosion-causing elements (oxygen, salt, moisture, etc) from affecting your parts. It’s important to remember that VCI’s will completely evaporate when parts are removed from the VCI, so no cleaning or removal is necessary, even if the parts are to be welded or painted.
CREATE A BARRIER
One final suggestion is to make sure that your metal parts are not in direct contact with wooden pallets, wooden crates, and corrugated boxes. Moisture, acids, and chlorine that is common in these products can all accelerate corrosion, especially in those areas where the parts are in direct contact with the wood or corrugated. This is known as contact corrosion, and it will be prevented if you create a VCI barrier between your parts and the wood or corrugated. Simply place a sheet of VCI paper or VCI poly sheeting between the parts and the wood or corrugated, or line corrugated boxes with a VCI poly bag or VCI paper.
By following these three simple procedures, you will greatly reduce the likelihood of corrosion and rust affecting your parts, your bottom line, and your reputation.
