Cortec Packaging for Long-Term Metal Parts Rust Prevention

Cortec Corp.’s VpCI-126 vacuum bags offer the protection of its basic VpCI-126 film, but include an extra barrier against moisture and oxygen for enhanced corrosion inhibition during long-term storage or harsh shipping conditions.

The bags can be vacuum-packed and are well suited for automotive build-ahead programs, all-time buys or other long-term metal storage applications, the company says. Metals packaged inside the vacuum bags are said to receive continuous protection against salt, excessive humidity, condensation, moisture, aggressive industrial atmospheres and dissimilar metal corrosion.

The VpCI molecules in the film vaporize and condense on metal surfaces in the enclosed package, forming a protective molecular film that doesn’t need to be cleaned off before the contents can be used.

VpCI-126 vacuum bags are an easy way to use loads and eliminate rubbing of small parts during transit and storage. Packaging is as simple as placing the clean, dry parts inside the bags and sealing them with standard vacuum packaging equipment.

The see-through film makes it easy to identify parts packed inside the bags without having to open the package and break the vacuum-packed seal, the company says. All the while, the metal parts inside continue to be protected against moisture, oxygen and corrosion without requiring conventional rust preventives such as oils and desiccants.
