Salem packs castings, foundry metal and engineering kits under wet-season humidity. The packing failure is usually geometry: cavities that film cannot contact, sharp edges that puncture bags, and open store dwell after shakeout or machining. A global manufacturer specifies multimetal VCI wrap, bags and emitters around that geometry. Export lots still need barrier free volume and sized desiccant when ocean weeks apply.
| Step | Why foundries need it | Failure if skipped |
|---|---|---|
| 1. Cool and dry the metal | Warm or wet castings sweat inside the pack | Rust from hour one under a perfect-looking wrap |
| 2. Protect sharp edges | Casting fins and corners tear film | Silent pinholes for the whole voyage |
| 3. Place emitters in cavities | Vapour must reach internal surfaces | Outside looks fine; bore and pocket rust |
| 4. Wrap or bag and close free volume | VCI needs a sealed atmosphere | Open wrap in wet-season air does nothing |
| 5. Unitise for handling | Foundry yards abuse packs | Torn free volume before the truck leaves |

With VCI and desiccant for multi-week export sealed life.
View Full SpecsUsually free water, open corner seals, missing cavity emitters, or bag punctures on sharp edges. Fix the process sequence, not only the film brand.
Large castings usually need wrap or shrink plus emitters for cavities. Small machined kits often need sealed multimetal bags.
Ask for edge protection and a film form that can be sealed without snagging. Thickness alone does not replace edge boards.
Yes under roof if metal is dry. Do not seal monsoon free water into the free volume.
When sealed life includes multi-week ocean humidity after coastal gate-in.
Grade-tied MIL-PRF-22019E and NACE TM0208 documentation where applicable, SDS, ISO 9001 and 14001 certificates, and a method note.
No. BENZ is a global protective packaging manufacturer applying VCI systems to foundry and engineering routes including Salem.
Salem is written as foundry and cavity-first. Coimbatore is pumps, motors and broader engineering density.
