Cortec® Case History Spotlight #731: Long-Term Storage of Auto Service Parts

Automakers who manufacture thousands or millions of service parts in advance must find ways to keep them corrosion-free for 10, 20, or 30 years after a model has been discontinued. In 2020, this need arose for a major automaker who needed to preserve thousands of rear differential units for up to 15 years.

The automaker turned to CorrLam® LD VpCI® Barrier Laminate and Cor-Pak® 1-MUL Pouches, two products that had been on their specifications for 20 years. The differentials were placed in CorrLam® bags with a Cor-Pak® 1-MUL or 8-MUL Pouch for added protection. The bags were either heat-sealed or sealed with long-term preservation tape.

This system is ideal for long-term storage because it does not absorb moisture, leave a stain, or require the use of liquid rust preventatives that need to be cleaned off later. Better still, it has an excellent track record with multiple automakers over the last two decades!
