Bearings are highly vulnerable to corrosion and should be installed rust-free for best results. However, they face many dangers simply on their way from the manufacturer to the end user. During this time, they can be exposed to fluctuating temperatures and humidity levels that lead to corrosion. This problem can be easily avoided by wrapping bearings in a piece of VpCI® Paper to protect them during the transit and storage period. Here are three great options.
CorShield® VpCI®-146 Paper is a basic but premium VpCI® paper for corrosion protection. It can be used to individually wrap bearings, or it can be used for interleaving between multiple layers of bearings inside a large package. Vapor phase Corrosion Inhibitors coated onto the paper carry out their protective function by vaporizing and adsorbing onto metal surfaces in a molecular protective layer while the package is closed. Both sides of CorShield® VpCI®-146 offer protection, so there is no guesswork deciding which side of the paper to face toward the bearing.
A creped version of CorShield® VpCI®-146 offers a little extra cushioning where needed, with the potential to help catch any pooling residual oils from the bearing. Small strips of CorShield® VpCI®-146 Creped make it easier to wrap ring-shaped bearings more closely by threading small, pliable strips of protective paper through the center opening.
EcoShield® VpCI®-144 Paper is a great choice where extra protection against moisture ingress is needed—or where bearings already contain lubricants that could leak out and damage the packaging. EcoShield® VpCI®-144 contains a barrier coating on one side and a VpCI® coating on the other for this dual protection.
An additional reason to choose one or more of these papers is that they represent the circular economy in action. All three are USDA Certified Biobased Products (made from renewable materials) that are recyclable. Contact us today to order your supply: https://www.cortecpackaging.com/contact-us/.
