Corrosion Inhibiting Stretch Film

Cortec offers EcoStretch compostable corrosion-inhibiting stretch film featuring Nano VpCI designed for stretch-wrapping metal equipment or components that need to be kept rust-free.


Cortec's machine-grade stretch wrap combines commercially compostable resins with Vapor phase Corrosion Inhibitor Technology (VpCI®) for corrosion protection of multiple metal types, including aluminum, galvanized steel, carbon steel, silicon steel, stainless steel, copper, brass, and cast iron. It meets the ASTM D6400 standard for commercial composting and may avoid tariffs, fines, and tip fees in areas where PE is prohibited or restricted. EcoStretch’s potential applications for warehousing or shipment of metals include:

• Bundling of metal parts

• Palletizing of metal equipment

• Packaging of steel coils

Workers simply substitute EcoStretch on existing stretch-wrapping equipment and use as normal, increasing tension as needed since EcoStretch is highly elastic. The self-adhering film bonds each layer to itself for added strength. Once the metals are wrapped, EcoStretch will provide contact, barrier, and vaporphase corrosion inhibition while also helping keep dust, dirt, and moisture off warehouse stock. EcoStretch is shelf and curb stable and will retain its integrity until disposed of properly. After use, the EcoStretch can be sent to a commercial composting facility to turn into a soil amendment for future use rather than adding to plastic buildup in landfills or in the environment.
