Volatile Corrosion Inhibitors

VCI paper or VCI film can be confusing when selecting an anti-corrosion packaging material for metals. The application requirements and consumer preferences heavily influence the selection. To help with the selection, here are some facts and benefits of VCI Film vs VCI Paper.

What is VCI Paper?

VCI Paper is made from high-quality neutral natural kraft paper, intended to preserve ferrous and non-ferrous metals. When VCI paper is used to wrap or surround metal objects, the VCIs become active and fill the vapour space inside the packing. On the metal’s surface, the VCI ions create a shield of defence that keeps moisture out and prevents rust.

Using ultra-safe, simple-to-apply VCI paper, businesses can preserve metal and metal parts without the mess and inconvenience of oil and grease-based coatings.

Facts about VCI Paper

VCI Paper provides a faster vapour corrosion inhibitor because the paper is more porous than film as a carrier. The VCI chemical can leave the paper quicker and fill the confined airspace faster than film. VCI Paper works better at securing susceptible sections, as the paper is porous. It also has better secondary absorption properties and a wider field of view than VCI film.

Benefits of VCI Paper

Biobased Rather Than Plastic: 

One of its benefits is that VCI Paper is a naturally biobased packaging material. The material is advantageous for consumers concerned about the environment who wish to switch to renewable-source items from plastic and petroleum-based.

Lower Risk of Pollution:

Additionally recyclable are VCI papers, providing a variety of non-polluting disposal choices.VCI Paper can be disposed of improperly without causing as much pollution as VCI Film, even though VCI Film can also be recycled.

Minimal Moisture Absorption and Cushioning:

For delicate parts like bearings, VCI Papers naturally provide cushioning. They can also take up extra moisture from pieces stacked at higher temperatures than advised.

 

What is VCI Film?

VCI film shields metal from rust and corrosion. The VCI film is a physical barrier to keep metal parts dry and free of impurities such as moisture and dust. It also emits a rust-eliminating vapour corrosion inhibitor to form a thin layer of protection on the metal’s surface. VCI film is a simple, dry, clean packaging option for metal and metal components available in rolls, sheets, VCI bags and tubes.

Facts about VCI Film

VCI Film provides the dual advantage of barrier materials and anti-corrosion properties. It is ideal as a bin liner bag for large bulk items (nuts, bolts) in bins and for bulky machinery that cannot be wrapped in paper. VCI Film, particularly high-density polyethene, is conformable and might suit trays with cavities better as a tray liner. It is more versatile and can be transformed into more practical packaging techniques such as zipper bags, tubing, and elastic bonnets.

Benefits of VCI Film

Robust Physical Barriers:

The plastic creates a more durable moisture barrier and can stand better in high moisture settings like export transportation. VCI Film is superior by nature for long-term protection in more hostile environments.

Several Practical Formats:

VCI Film is available in a wide range of convenient formats and aesthetics. Put a metal component inside a VCI Bag, then zip it up and heat shrinks the whole thing or both!

More Flexible Storage Alternatives:

VCI Film is a VCI protective additional strength grade that is durable enough for outdoor storage. That outdoor storage protection is upgraded to hurricane-strength durability.

 

Conclusion

Users can wrap metal parts in VCI Paper before placing them in a bag to take advantage of both benefits. It is advantageous to have a robust physical moisture barrier on the surface, cushioning and moisture absorption on the inside.

However, users should choose the type of packaging material that best meets their specific corrosion protection requirements.
