corrosion inhibitor paper parts can look perfectly fine when they are packed, yet corrosion may start later inside the box. Moisture, heat, trapped air, and industrial pollutants can all affect the surface during storage or shipment. Copper, aluminium, cast iron, and mixed-metal assemblies may need even more care, especially when they remain packed for several months.

VpCI-149 Paper is made for this kind of protection. It is a soft corrosion inhibitor paper that wraps easily around metal parts and helps limit rust, tarnish, and oxidation inside the package. The paper does more than cover the component. Once enclosed, it releases protective vapours that move through the available space and settle on exposed metal surfaces. This allows the paper to protect flat areas, corners, small gaps, and recessed sections without leaving a thick layer of grease or wax. It can be used with dry parts as well as components that carry a light oil film. Depending on the job, it may serve as a full wrap, carton liner, separator, interleaving sheet, or insert inside a larger crate.

Nassguard supplies VpCI-149 Paper across Qatar, including Doha, for factories, warehouses, workshops, maintenance teams, and export packing companies.

What is VpCI-149 Paper?

VpCI-149 Paper is a natural kraft paper treated with Vapor Phase Corrosion Inhibitor technology. It is developed to protect a broad range of ferrous and non-ferrous metals. The paper is especially useful where several metal types are packed together. Steel, cast iron, copper, brass, aluminium, galvanized surfaces, and solder can all be protected with the same material. Its soft construction allows it to follow the shape of uneven or irregular parts. This is helpful when wrapping bearings, cast components, forged pieces, electrical items, tools, and machinery parts. After wrapping, the inhibitor compounds slowly release into the enclosed package.
They spread through the air and form an invisible protective layer over the metal. This layer helps slow the corrosion process caused by humidity, condensation, and airborne contaminants. The protection is dry and clean. In most cases, the metal can be used, painted, welded, soldered, or processed without removing a heavy coating first. The kraft base is neutral and does not rely on chlorine bleaching. The formulation is also free from nitrites, phosphates, silicones, chromates, and heavy metals.

Applications Across Qatar and Doha

Qatar

A component may leave a workshop, stay in a warehouse, pass through a port, and then travel to a project site. During this period, heat and humidity can create condensation inside the packaging.

• Oil and gas spare parts
• Steel and aluminium components
• Machinery and equipment packing
• Bearing and gearbox storage
• Pipe and tube protection
• Metal sheet and coil interleaving
• Automotive parts distribution
• Marine equipment storage
• Electrical component packaging
• Heavy-equipment maintenance
• Workshop inventory protection
• Long-term warehouse storage
• Export packing for industrial goods

Doha

In Doha, the paper is suitable for businesses that regularly handle finished, machined, cast, or fabricated metal products.

• Engineering workshops
• Machinery repair companies
