Corrosion-protective bags and papers can offer a corrosion-protection cycle of up to 24 months, or even longer. However, this does not necessarily mean they are superior corrosion-proof packaging solutions that guarantee product integrity against corrosion. The effectiveness of the corrosion protection of these bags and papers hinges on numerous factors.

VCI bags and papers perform effectively under relatively sealed conditions; they can still offer rust prevention even if not fully sealed. However, if the product undergoes machining without water-based cleaning and doesn't reach a certain drying temperature, the effectiveness may vary by product.

Volatile organic corrosion inhibitors increase with temperature, and they cannot be stored or transported in environments exceeding 40°C. They should be kept away from direct sunlight and heat sources, and metal should be cooled before packaging.

2. Vapour phase corrosion inhibitors will see a reduction in their corrosion-inhibiting effect in environments with relative humidity above 75%. The humidity during the packaging of finished products should not exceed 75%, and during storage and transportation, it should be avoided to get damp. Vapour phase rust prevention materials can be used simultaneously with desiccants.

3. Prior to packaging, ensure the items are clean and free of fingerprints. Packaging personnel must wear gloves when handling metal objects and during the packaging process.

During rust-proof packaging operations, the workplace should be kept away from "highly corrosive substances such as acids and alkalis and acidic etching gases."
