Corrosion Protection

Products that are transported for a longer period of time or stored for an extended period are often in need of corrosion protection. Corrosion protection packaging prevents corrosion without having to treat the metal with oil, grease or paint.

With corrosion protective packaging you can easily prevent corrosion on your products.

Corrosion is a significant problem in the handling, storage and shipping of products. Bare metal parts corrode easily. Temperature changes, contaminated air, sea salt and moisture, all create corrosion. All products with bare metal (bearings, engines, parts, electronic devices) need to be protected. Products in overseas transit go through a complex process of loading, unloading, manipulation, warehousing and control. So many parameters can influence the quality of the metal. Highest care is needed for a problem-free arrival.

Nefab has provided corrosion protection solutions for many industries over the years. Through its competence and global network Nefab can provide a customized solution anywhere in the world, giving customers the ability to dispatch products worldwide without humidity or corrosion damages. 

How to prevent corrosion:

There are several different solutions for protecting the product from corrosion depending on parameters such as: product type, means of transportation, and the length of the transit time.

LDPE film or HDPE film with desiccants and/or VCI emitters

In some applications when products are not too sensitive to corrosion, when protection is only required for very short storage or when the level of humidity in the environment is low, a combination of standard plastic film + desiccants and/or VCI emitters may offer enough corrosion protection.

Aluminum-barrier film + desiccants

Aluminium barrier material can be used as a packaging in combination with desiccants. After a product has been packed, the air is pumped out and the desiccants absorb the remaining moisture. Aluminium barrier foil has a considerably lower water vapour transmission rate than bags made of LDPE or HDPE and reduces the required amount of desiccants in export packaging.

VCI = Volatile/Vapour Phase Corrosion inhibitors

VCI is an additive that can be added to most common packaging materials. Once exposed to the air, the additive vaporizes in the air and deposits itself as a thin layer on metal surfaces. This layer prevents humidity from reaching the metal and the process of corrosion is prevented. VCI technology is suitable for corrosion protection during shipment, temporary storage between manufacturing processes and mothballing of seldom used equipment.
