Compostable Corrosion-Inhibiting Stretch Film Comes to MarketCompostable Corrosion-Inhibiting Stretch Film Comes to Market

Cortec has introduced what it’s calling the “world’s first compostable corrosion-inhibiting stretch film.” EcoStretch is the next generation in a line of commercially compostable film technologies offered by Cortec, which specializes in the development of corrosion protection and packaging technologies that minimize environmental impact.

The machine-grade stretch wrap combines commercially compostable resins with Vapor phase Corrosion Inhibitor (VpCI) technology that imparts corrosion protection to multiple metal types, including aluminum, galvanized steel, carbon steel, silicon steel, stainless steel, copper, brass, and cast iron.

EcoStretch meets the ASTM D6400 standard for commercial composting and may avoid tariffs, fines, and tip fees where polyethylene is prohibited or restricted. It is suited for stretch-wrapping metal equipment such as molds and components that need to be kept rust-free while minimizing the environmental impact of traditional plastic packaging.
