Daubert Cromwell MetalGuard VCI Gusseted Bags are innovative packaging solutions made from a superior strength, flexible VCI (Volatile Corrosion Inhibitor) film. These bags work by releasing a special VCI formula that vaporizes within the sealed bag, forming an invisible, molecular protective layer on the surface of your metal parts. This protective layer actively prevents rust and corrosion by blocking the electrochemical reactions that cause degradation, ensuring your items remain pristine.
The VCI technology in Daubert Cromwell MetalGuard bags is exceptionally effective because it operates in both vapor and contact phases. The VCI molecules not only protect surfaces they physically touch but also vaporize to reach all exposed and even hard-to-reach internal surfaces, like those within complex machinery parts. This comprehensive coverage creates a full protective atmosphere inside the bag, shielding against moisture, salt, sea air, and other corrosive elements.
Yes, these bags are indeed a more environmentally friendly option compared to traditional rust prevention methods like messy oils and desiccants. They eliminate the need for additional chemicals, are free of nitrates, and are recyclable, reducing your environmental footprint and making disposal much simpler and more responsible.
Daubert Cromwell MetalGuard VCI Gusseted Bags are remarkably versatile, providing excellent protection for a wide array of metals and alloys. This includes mild steel, cast iron, stainless steel, galvanized steel, copper, brass, bronze, zinc, tin, and even silver, making them a comprehensive solution for diverse metallic components.
When properly sealed and used for indoor storage, Daubert Cromwell MetalGuard VCI Gusseted Bags offer extended, long-term corrosion protection. The protective VCI layer typically forms within 24 hours under normal ambient conditions and can provide protection for up to 24 months or even longer, depending on the storage conditions.
For optimal results, ensure your metal parts are clean and dry before packaging. It's also recommended that packaging personnel wear gloves while handling bare metal parts to prevent fingerprints or oils from interfering with the VCI protection.
These gusseted bags are heat sealable, meaning you can achieve a secure and airtight closure using a poly hand sealer. A recommended setting is typically 2 seconds at 180°C (356°F) to ensure the VCI vapors are effectively contained within the bag, maximizing protection.
Absolutely! The gusseted design of these bags allows them to expand, making them ideal for covering large, bulky, or irregularly shaped items, pallets, and even for lining crates, gaylords, and boxes, providing comprehensive protection for your substantial components.
Yes, one of the convenient features of Daubert Cromwell MetalGuard VCI Gusseted Bags is that the VCI layer can regenerate to a certain extent. This means you can briefly open the bag to inspect your parts without significantly compromising the long-term effectiveness of the corrosion protection, though it's always best to reseal them quickly.
For optimal effectiveness, the metal part should be placed no more than 12 inches (30 cm) from the Daubert Cromwell MetalGuard VCI film. The closer the proximity, the more efficiently the VCI molecules can condense and form their protective layer on the metal surface.
