Nagoya-region auto and precision plants move kits between machining, plating, assembly and warehouse under tight process control. Flash rust still starts when free volume stays open multi-day. Export programmes add Japanese port dwell and multi-week ocean humidity later. A global manufacturer specifies multimetal VCI film for kit free volume after dry clean, VCI stretch for unitised cartons, anti-static VCI only when ESD modules apply, and aluminium barrier free volume with sized desiccant when ocean weeks apply.
| Ladder step | Pass rule | If miss |
|---|---|---|
| Clean and dry | No free water or process residue | Rust under sealed bag |
| Multimetal free volume | Bag or wrap closed on the kit | Open poly through kanban days |
| Grade matches metal list | Steel, plating and aluminium covered | Selective staining |
| Stretch after bag | Unitise only after free volume exists | Stretch-only pallets |
| Barrier if ocean weeks | Barrier free volume + desiccant with VCI | Film-only long export stains |
Mixed plating free volume for multi-day plant holds.

With VCI and desiccant for multi-week export sealed life.

Open free volume during multi-day kanban stores, stretch-only pallets without part bags, and under-specified multimetal grade on mixed plating kits.
Yes when bare metal sits multi-day before the next process or export staging. Open poly is not a vapour system.
When sealed life includes multi-week ocean humidity after Japanese port exit.
Grade-tied MIL-PRF-22019E and NACE TM0208 documentation where applicable, SDS, ISO certificates and a method note covering hold days and clean standards.
No. BENZ is a global protective packaging manufacturer.
Clean faces still need closed free volume. Cleanliness is the gate; VCI is the vapour control after seal.
No. Use anti-static VCI only when ESD rules apply. Multimetal VCI is the default corrosion free volume.
Share plant process, hold days, metal and plating list and export path if any. The reply should name film form, clean gate and whether barrier plus desiccant are required.
