Volatile Corrosion Inhibitor bags-Blue Vci Poly Bags

volatile corrosion inhibitor bags

Blue VCI Poly Bags (Volatile Corrosion Inhibitor polyethylene bags) are plastic packaging materials infused with a corrosion-resistant polymer designed to protect metal parts from rust and corrosion during storage and shipping. The blue color of the bags is commonly used to identify them as VCI-treated and also to improve UV resistance. These bags are widely used in industries such as automotive, aerospace, manufacturing, and metalworking to protect against moisture, salt, and other corrosive agents

How to Use Blue VCI Poly Bags:

  1. Clean and Dry: Ensure that the metal parts are clean and dry before placing them in the bag.
  2. Enclose the Part: Place the metal part inside the bag, making sure it is fully enclosed.
  3. Seal the Bag: Seal the bag tightly to prevent air, moisture, and contaminants from entering.
  4. Storage: Store the packaged items in a cool, dry place for best results. Blue VCI poly bags provide effective corrosion protection for months to years, depending on storage conditions and the type of VCI formulation.

Key Features of Blue VCI Poly Bags:

  1. VCI Technology: The bags are embedded with vapor corrosion inhibitors (VCIs) that release protective molecules into the enclosed space, forming an invisible barrier on the surface of metals, preventing corrosion.
  2. Multi-Metal Protection: These bags can protect various types of metals, including ferrous (iron and steel) and non-ferrous (aluminum, copper, brass) metals.
  3. No Surface Residue: Unlike traditional rust-preventive oils or coatings, VCI poly bags do not leave any oily or greasy residue, which makes them suitable for parts that need to remain clean.
  4. Moisture Barrier: Polyethylene material serves as a moisture barrier, helping prevent rust by blocking the passage of water vapor.
  5. Ease of Use: The metal parts simply need to be placed inside the VCI bag and sealed. There is no need for additional rust-proofing oils or greases.
  6. Recyclable: Many blue VCI bags are made from recyclable materials, making them a more environmentally friendly option compared to single-use coatings or treatments
