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 February 24, 2010It is estimated that corrosion costs American Industry $350 BILLION dollars per year. This cost is ultimately passed on to consumers. Corrosion is not only unsightly; it can damage the structural integrity of metal parts. For highly machined metal parts, even a small amount of corrosion can render the parts unusable. Your customers may reject your parts and return them to you for scrap or re-work. This process is not only costly in terms of money, but also in terms of your company’s reputation. Traditional corrosion inhibiting oils and greases are not only costly, messy, and harmful to the environment, but when your customers receive their parts, the oils and greases require removal. Often, the removal of these oils requires the use of solvents, and of course, additional labor. These solvents are also hazardous to the environment, and hazardous to employees’ health.
Corrosion is a natural, electrochemical process that causes metal to rust, weaken and eventually break down. Rust and corrosion are unsightly, dangerous, and costly to metal parts manufacturers. Many foundries, machine shops, metal stamping companies, metal forming companies, metalcasters, and other metal parts manufacturers use messy Rust Preventative (R.P.) Oils to prevent corrosion and rust on their parts. The oils create a barrier between the metal surface and the elements in the atmosphere (oxygen, moisture, salt, contaminants, etc.) that cause corrosion. R.P. Oils can be effective against corrosion, but they are also costly not only in terms of dollars, but they are also costly in terms of their ill-effects on the environment and your employees’ health.
Here are just 7 reasons why R.P. Oils are so costly:
1. Applying rust preventative liquids by spraying, brushing or dipping is extremely labor-intensive
2. Disposal of drums and oil-soaked rags is very expensive
3. Storing flammable R.P. oils in your plant can dramatically increase insurance premiums
4. R.P. Oils pollute lakes, streams, and groundwater
5. R.P. Oils contain Volatile Organic Compounds (VOC’s) which are harmful to the earth and employee’s health
6. Common spills of R.P oils often lead to employee slip and fall accidents
7. Many R.P. oils contain carcinogens
There is a modern, clean, dry, effective way to prevent rust and corrosion, and their many costs. The solution is Green
VCI Paper and VCI Poly Bags. Green VCI Paper and Green VCI Poly products are a unique line of environmentally-friendly vapor phase corrosion inhibitors. Rust inhibiting chemicals are coated or impregnated into paper or polyethylene. When metal parts are packaged in Green VCI Paper or Green VCI Poly, the rust inhibitor chemicals migrate off of the paper or poly and deposit on the surface of the metal parts. Green VCI technology works on a molecular level. The rust inhibitor molecules completely cover all surfaces of the metal (including hard to reach places) and prevent oxygen and moisture from causing corrosion and rust on the metal.

Published February 19, 2010Corrosion, and in particular rust, costs metal parts manufacturers and foundries an average of more than 350 billion dollars annually! During manufacturing and shipping, metal parts can be exposed to moisture, causing rust. Many times clients return these rusted parts, doubling shipping costs, and sometimes causing the company sandblasting, repair, or replacement costs.
VCI packaging can reduce corrosion of metal parts in the storage and shipping process. VCI stands for volatile corrosion inhibitor. The VCI process uses environmentally friendly corrosion inhibitors that are coated on packaging paper or polyethylene. These materials are used to package metal parts so that the corrosion inhibitor chemicals completely cover all surfaces of the metal. This prevents oxygen and moisture from causing corrosion and rust on the metal.
There are several VCI packaging products, designed for different types of metal. These include VCI paper poly bags, and foam. In addition, there is a dry coat rust inhibitor liquid that can be used to coat metal parts for added corrosion protection. VCI packaging works because very small amounts of the inhibitor are continually released by evaporation into the enclosed air space in the package and then settle on the metal surfaces to form an invisible thin film of protection from corrosion.
Sometimes in addition to using VCI packaging, it is important for metal parts manufacturers to assess the manufacturing process to help insure corrosion free parts. Workers who handle metal parts should wear gloves because fingerprints containing salts and humidity that can cause corrosion. It is important to quickly package a ferrous part as soon as it is manufactured. These parts should be kept clean of moisture, dirt, or corrosion already present because VCI material cannot repair already damaged parts.
For best results, the metal part should be no more than 18 inches from the packaging, and metal objects like coils of steel wires should be tightly wrapped with overlapping VCI film. In addition, VCI Material should not to be stored for more than six months before they are used. Finally, it is best to test the packaging and shipping before ordering VCI material in bulk, and to consult with a VCI packaging expert to determine the best packaging method for your metal parts.
