Chicago and the wider Midwest move industrial metal through humid summers, cold winters and long warehouse dwell. Cold metal entering warm plants sweats. A global manufacturer specifies multimetal VCI film for sealed free volumes after dry clean, with barrier free volume and desiccant when sealed humidity lasts multi-week export legs.
Chicago-region risk is dual: humid summer store dwell and winter cold-to-warm condensation. Free water sealed after a cold trailer move is a process failure, not a film brand failure.
| Driver | Effect | Film response |
|---|---|---|
| Winter condensation | Free water on cold metal | Dry fully before seal |
| Summer humidity | Flash rust after wash | Same-shift sealed bags |
| Warehouse dwell | Days of store | Design free volume honestly |
| Export legs | Long sealed humidity | Barrier free volume + desiccant |

Multimetal VCI bags after dry clean. Stretch for pallet cartons.
Cold metal brought into warm buildings sweats. Free water sealed into a bag starts corrosion. Dry fully, then seal.
For multi-week bare-metal ocean humidity, pair VCI with aluminium barrier free volume and sized desiccant.
Grade-tied MIL-PRF-22019E and NACE TM0208 documentation where applicable, SDS, ISO certificates and a method note.

Design free volume for days of store, not only truck hours.
Nested stampings often need interleave. Machined kits usually need sealed film bags.
