Export & Preservation Packaging
VpCI packaging and traditional barrier packaging methods both have merit. Each method serves certain purposes, some of these purposes are similar and some are not. At Heritage Packaging we strive to help our customers not only understand the differences between these two methods but also help them decide which method of packaging will best meet their requirements for the least amount of money. Each packaging application should be closely evaluated to determine the most sensible course of action. The following comparison illustrates the subtle differences between VpCI packaging and traditional barrier packaging and is an excellent starting point for determining what type of package your product needs. This comparison assumes that a BluGuard-VCI Anti-Corrosion Lamination is the VpCI material being evaluated (BluGuard-VCI Anti-Corrosion Laminations are the only film/foil/poly laminations available with an integrated VpCI impregnated sealant layer).
- No pre-cleaning of parts
- No post cleaning of parts
- Air tight packaging is helpful but not essential
- Effective from -40°F to +160°F
- No desiccants required
- No gas flushing required
- Large enclosures can be conditioned with additional VCI emitters
Traditional Barrier Packaging
- Parts may require pre-cleaning & oiling
- Post cleaning of oils may be needed
- Must be air tight and interior atmosphere kept at or below 40% relative humidity
- Effective from -40°F to +160°F
- Must be periodically monitored to ensure relative humidity is acceptable, desiccants changed and gasses must be re-flushed
- Desiccants required
- VCI emitters can be used

- 7/8 Height Cover To 1/8 Height Base Tray
- 1/2 Height Cover to 1/2 Height Base Tray

Why It Works
The flange extends away from the cover at a right angle and lines up exactly with the base sheet or tray. The flange is manufactured to be three inches wide to provide a large horizontal area for sealing. This horizontal area eliminates an installer’s need to manipulate and possibly tear the cover while sealing it to a base sheet or tray. The ease of closure also extends itself to a simplified vacuum sealing method (See the reverse side of Sheet).
- The flange extends out from the cover at a right angle to lay flat against a base sheet or a tray’s matching flange.
- The flange can be heat sealed to the base sheet or attached with factory applied pressure sensitive adhesive.
- The flange facilitates simplified vacuum sealing.
- Flanged covers are available in any heat sealable material.
- Flanged three dimensional covers are easier to install and are more reliable than flat bags and hand-sealed covers.
- State of the art industrial machinery ensures all seals are hermetic.

Barrier covers and shrouds are fabricated to meet customer specific needs. These needs often include various accessory items from any number of secondary vendors. Accessory items range from vapor proof zip-track to maximum shock and vibration recorders.
Commonly Used Items Include
- Vacuum Accessories
- Humidity Indicators
- Temperature Indicators
- Tilt Detectors
- Shock & Vibration Recorders
- Radio Frequency ID Tags
Patent pending Vac-U-Valve for easy evacuation of gasses from export or preservation cover systems.
Humidity indicators for monitoring humidity level within a package.
Numerous forms of VpCI Emitters for optimum anti-corrosion protection of enclosed spaces.
Example One – Large Machine Cover
Heritage Packaging designed and fabricated slant-top three dimensional shrouds from BluGuard-VCI Anti Corrosion Laminations to pack these machines. Heavy duty BluGuard-VCI-Outdoor was used for the base tray while BluGuard-VCI was used for the shroud. Bolt holes were located and sealed with gaskets for vacuum-packing. The machines were successfully shipped to Japan by sea without the use of desiccants or other accessories, completely corrosion free.
Example Two – Large Machine Cover
Heritage Packaging designed and fabricated three dimensional covers and trays for export shipping computer controlled manufacturing equipment overseas. The machines were bolted to their skids and vacuum packed in our custom covers. The barrier and VpCI properties of the cover ensured that upon its arrival the equipment would not be corroded or damaged. This particular machine was crated as well.
Example Three – Mainframe Cover
Heritage Packaging designed and fabricates three dimensional barrier covers for shipping and storing sensitive mainframe computer units. The covers are closed via a factory applied pressure sensitive adhesive that forms an air tight seal in the cover. Tempered particle board serves as a medium for the mainframes to slide across while they are being loaded into their covers.
