The Sustainability Question Every Buyer Asks

If your company has ESG compliance targets, you've been asked: "Is our packaging actually sustainable?" For companies using VCI film to protect metal parts, the answer depends entirely on the manufacturer. Here's what you need to know.

Is VCI Film Recyclable?

Yes — quality VCI film manufactured from virgin LDPE (resin code 4) is 100% recyclable through standard polyethylene recycling streams. The VCI chemicals are present in trace amounts (typically 3-8% by weight) and do not interfere with the recycling process.

BENZ Packaging also manufactures VCI Bio-Film — a fully compostable alternative made from plant-based resins. It provides identical corrosion protection but decomposes under industrial composting conditions, leaving zero micro-plastics behind.

The Toxic Nitrite Problem in Cheap VCI

Here's what generic VCI suppliers don't tell you: most cheap VCI films rely on Sodium Nitrite as the primary anti-corrosion chemical. While effective at stopping rust, nitrites are classified as severe occupational hazards. When nitrites combine with secondary amines (also commonly found in cheap VCI) under heat, they form nitrosamines — confirmed carcinogenic compounds.

This is why BENZ Packaging formulations are 100% nitrite-free, amine-free, and heavy-metal free, manufactured exclusively with Propatech Italian masterbatches that comply with:

  • TRGS 615 — German Technical Rule for Hazardous Substances (bans nitrites and reactive amines)
  • REACH — EU chemical safety registration (European Chemicals Agency)
  • RoHS — Restriction of Hazardous Substances (verified by Intertek Report No. DELH23009988)

If you export to Europe through ports like Rotterdam, Hamburg, or Antwerp, a nitrite-laden VCI film can trigger port seizures and disposal fines.

VCI Film vs. Rust Preventive Oil: The Real Environmental Comparison

The biggest sustainability advantage of VCI isn't about the plastic — it's about what VCI replaces:

VCI FilmRust Preventive Oil
At destinationParts ready to use immediately — zero cleaningRequires caustic solvent baths to degrease
Water usageZeroHundreds of thousands of litres annually
Hazardous wasteZero — recyclable PE filmContaminated solvent requiring licensed disposal
Worker exposureNon-toxic (TRGS-615 compliant)Skin contact, inhalation of petroleum vapors

BENZ Packaging's Sustainability Programmes

Our commitment goes beyond VCI chemistry. BENZ operates two core sustainability programmes:

  • CarbonSmart — Carbon footprint tracking and reduction across our entire manufacturing and logistics chain
  • WasteSmart — Packaging material reduction, recycling partnerships, and transition to bio-sourced inputs

Our VCI Enviro-Films are specifically engineered for companies pursuing aggressive net-zero packaging targets. They provide the same multi-metal protection as standard VCI film while aligning with circular-economy mandates.

Frequently Asked Questions

Is VCI film recyclable?
Yes. LDPE-based VCI film (resin code 4) is 100% recyclable. For companies needing compostable packaging, BENZ offers VCI Bio-Film.

Is VCI film toxic?
Premium VCI films complying with TRGS 615 are completely non-toxic. However, cheap generic VCI often contains carcinogenic Sodium Nitrite. Always verify TRGS-615 compliance with your supplier.

What is TRGS 615?
The German regulation banning nitrites and secondary amines in workplace chemicals. Required for all VCI products entering Germany or used by German OEMs.

Does VCI film leave residue?
No. VCI molecules dissipate within minutes of opening the package. Parts are immediately ready for painting, welding, or assembly with zero cleaning required — unlike rust preventive oils.
