Zerust® Natur-VCI® Film

The Zerust®/Excor® Natur-VCI® series is an internationally certified fully biodegradable and compostable Volatile Corrosion Inhibiting (VCI) packaging material designed to protect metal components from rust and corrosion during shipment and short-term storage.

Request Information

Zerust® Natur-VCI® products, with a thickness of 60 microns (2.3 mil) or less, pass the NACE Standard TM0208 VCI corrosion protection test to level 3, but also meet international standards for compostable plastics including ASTM D6400, EN 13432, and are certified 100% compostable by TUV Austria.

End of Life Disposal

Natur-VCI® film is engineered for safe disposal in a professionally managed composting facility, where the carbon in the film is utilized as a food source by micro-organisms to completely break-down the plastic into humus, water, and CO2. The resulting humus can be used as a natural fertilizer and/or soil amendment in agriculture. Natur-VCI® meets the ASTM D6400 “Standard Specification for Labeling of Plastics Designed to be Aerobically Composted in Municipal or Industrial Facilities” and is certified (Cert # TA8012004702) by TUV Austria for the European EN 13432 standard “Packaging – Requirements for packaging recoverable through composting and biodegradation – Test scheme and evaluation criteria for the final acceptance of packaging.”

Carbon Savings

By replacing 100 metric tons (100,000 kg) of conventional polyethylene plastic VCI packaging with Natur-VCI®, the following equivalent environmental benefits are achieved.**

After parts* are shipped to the end-user, the Natur-VCI® bags may be reused to collect food scraps at the end user’s facility and sent to their local compost site. Natur-VCI® meets ASTM D6400 and is certified by TUV Austria (Cert # TA8012004702).

*Parts cannot be coated with rust preventative oils, unless oil is certified compostable.

  • Certified Compostable
  • Powerful and safe corrosion protection and packaging combined in one step
  • Provides enhanced mechanical performance properties in terms of tensile strength, resistance to tearing, elongation at tear and puncture resistance in conformity with DIN EN ISO 527-3/2/200 and ASTM D1709/A. In many cases these properties allow the implementation of thinner films (i.e. 2.3 mil rather than 4 mil), allowing customers to reduce the environmental impact
  • Metals components are ready for use and assembly directly after being taken out of the packaging
