VCI Desiccant Bag – VCI-301 Moisture and Corrosion Protection
Moisture inside sealed packaging can create serious problems for metal products during storage and transportation. Changes in temperature can also lead to condensation, increasing the risk of rust on components, machinery and precision parts. The VCI Desiccant Bag VCI-301 combines moisture absorption with vapor-phase corrosion protection in a single packaging product.
VCI-301 uses natural minerals together with VCI corrosion-inhibiting ingredients. According to the manufacturer, the product absorbs moisture while its VCI components vaporize inside an enclosed package and form a protective molecular layer on exposed metal surfaces. The manufacturer recommends a basic usage rate of 100–130 g/m³.
Available from Alvina, VCI-301 supports industrial packaging requirements across UAE, Abu Dhabi, Dubai, Sharjah, Saudi Arabia, Riyadh, Jeddah, Dammam, Qatar, Bahrain, Kuwait and Oman.
What is a VCI Desiccant Bag?
A VCI Desiccant Bag combines two corrosion-control methods. The desiccant portion absorbs moisture from the surrounding atmosphere, while the Volatile Corrosion Inhibitor (VCI) portion provides additional protection against corrosion.
VCI-301 contains natural mineral materials and vapor-phase rust-inhibiting ingredients. Its breathable non-woven packaging allows the VCI components to move into the enclosed atmosphere. These components then reach exposed metal surfaces, including difficult areas such as cavities, holes and curved surfaces.
This combination makes VCI-301 particularly useful when companies need to store, transport or export metal components in enclosed packaging.

How Does VCI-301 Work?
VCI-301 works inside an enclosed packaging environment. First, its desiccant material absorbs moisture from the surrounding air. At the same time, the VCI ingredients vaporize through the breathable packaging material.
These corrosion-inhibiting molecules travel through the enclosed space and reach exposed metal surfaces. The manufacturer describes this action as forming a protective molecular film on the metal. Because vapor can travel around complex shapes, the protection can also reach cavities, holes and curved surfaces that direct-contact packaging materials may struggle to cover.
The manufacturer also states that after the desiccant reaches water saturation, it does not release water that could contaminate the protected components.
