1. Know the Type of Metal You’re Protecting
Different metals require different protection. Whether you’re storing steel, aluminum, copper, or brass, it’s important to select a VCI bag designed for the specific metal to ensure the best results. For example, aluminum requires bags with specific inhibitors to prevent staining, while steel needs general corrosion protection.
2. Choose the Right Size
The size of the VCI bag is crucial for effective corrosion prevention. A bag that’s too large or too small can compromise protection. Ensure the bag fits the item snugly to keep the inhibitor vapor around the metal surface, providing maximum coverage.
3. Consider the Environmental Conditions
The conditions your items will face—like humidity, temperature, and exposure to other elements—can impact how well your VCI bag works. Choose a bag that’s suitable for the specific environment where your items will be stored or shipped.
4. Customization for Unique Needs
At Atlantic Poly, Inc., we understand that every project is unique. That’s why we offer custom VCI bags tailored to your specific requirements. Whether you need a custom size, shape, or inhibitor formula, we’ve got you covered.
Choosing the correct VCI packaging is crucial to ensure your products receive adequate protection against corrosion. Different VCI packaging options have varying properties and are designed for specific applications. Selecting the wrong VCI product may result in insufficient protection, leading to potential damage, rust, and costly repercussions.
The purpose of this article is to guide customers in seeking the correct VCI packaging. By understanding the various factors to consider and the available options, you can make an informed decision and understand how to choose the correct VCI packaging for your specific needs.
When choosing VCI packaging, several variables should be considered to ensure optimal product corrosion protection. The main variables include:
Product Characteristics
Determine the type of material your products are made of (e.g., ferrous metals, non-ferrous metals, electronics).
Consider the sensitivity of your products to moisture, humidity, and other environmental factors.
Identify any specific requirements related to the electrical conductivity or static dissipation of your products.

Packaging Requirements
Evaluate the size, shape, and weight of your products to determine the appropriate packaging format.
Consider the packaging method (e.g., bulk packaging, individual wrapping) that suits your products.
Assess any special considerations such as fragile components, irregular shapes, or unique storage requirements.
Environmental Conditions
Assess the storage and transportation conditions your products will be exposed to.
Consider factors like temperature fluctuations, humidity levels, exposure to corrosive substances, and outdoor or indoor storage.
Choose VCI packaging materials that are compatible with the specific environmental conditions of your product’s lifecycle.
Duration of Protection
Determine the required length of protection for your products (e.g., short-term storage, long-term preservation, intermittent usage).
Consider the anticipated storage duration and the exposure to potentially corrosive elements during transportation and storage.
Once you have considered which variables apply to your product, you can decide which VCI product best suits your needs.
VCI Films
VCI films are a popular choice for wrapping or covering individual products or oversized items. These films are specifically designed to provide versatile and effective corrosion protection. They are available in various thicknesses and can be tailored to fit the specific dimensions of your products. VCI films create a protective barrier that shields the enclosed items from moisture, oxygen, and other corrosive elements. Their versatility makes them suitable for a wide range of applications in industries such as automotive, aerospace, electronics, and metalworking.
VCI Papers
VCI papers are protective papers treated with VCI chemicals, making them ideal for interleaving between metal parts or lining packaging containers. These papers commonly provide corrosion protection to individual components during storage or transportation. By placing VCI papers between metal surfaces, they effectively prevent direct contact and minimize the risk of scratches or damage. VCI papers are widely employed in automotive manufacturing, machinery production, and precision engineering industries.
VCI Bags
VCI bags offer a convenient solution for enclosing and protecting individual items or components. These bags are specially designed with VCI technology, providing corrosion protection throughout the entire enclosed space. VCI bags are available in various sizes and configurations, accommodating products of different shapes and dimensions. They are commonly utilised in industries such as electronics, automotive, metalworking, and industrial equipment manufacturing. VCI bags are effective for applications such as storage, shipping, and long-term preservation of metal parts, tools, and sensitive electronic components. VCI bags also work well as box liners.
VCI Liquids
VCI liquids are best suited for immersion and coating applications, making them ideal for metal pretreatment, surface preparation, and rust prevention. They excel in protecting complex and hard-to-reach areas where other forms of VCI packaging may be impractical. VCI liquids are effective in penetrating narrow gaps, crevices, and internal cavities, ensuring comprehensive corrosion inhibition. They are also advantageous for providing temporary or intermittent protection, making them valuable during various stages of production or intermittent use. Additionally, VCI liquids are well-suited for safeguarding large equipment and machinery that cannot be easily wrapped or enclosed. Their application creates a protective layer on exposed metal surfaces, extending the lifespan of the equipment.
Desiccants
By combining VCI with desiccants, comprehensive protection against both moisture and corrosion is achieved. They excel in applications where the elimination of excess moisture is critical, such as in enclosed spaces or during long-term storage. This combination proves especially beneficial in safeguarding sensitive equipment, electronics, and machinery, as it ensures the preservation of optimal conditions within the storage or packaging environment. The utilization of desiccants alongside VCI is particularly advantageous in industries such as aerospace, electronics, and automotive, where moisture-induced corrosion poses significant risks. Together, VCI and desiccants create a formidable defence against corrosion, extending the lifespan and reliability of metal components and assets.
