Frequently Asked Questions

• What makes Cortec EcoSonic ESD Stretch Film unique compared to standard stretch films on the market?

This film stands out because it's not just a stretch film; it’s specifically engineered with advanced static dissipative properties and multi-metal corrosion inhibitors, thanks to its Nano VpCI technology, offering comprehensive protection against both electrostatic discharge (ESD) and rust in a single solution, which is quite different from what you'd typically find.

• How does the Nano VpCI technology within this stretch film actually protect metals from corrosion?

The Nano VpCI technology works by releasing invisible vapor phase corrosion inhibitors into the enclosed packaging environment. These intelligent molecules travel through the air and form a microscopic protective layer on all exposed metal surfaces, effectively blocking moisture, oxygen, and other corrosive elements from causing rust and tarnish without needing any messy oils or greases.

• Can this film be used for a variety of metals, or is it specific to certain types?

Absolutely, it's designed to provide multi-metal corrosion protection. This means it’s effective for a wide range of common industrial metals including carbon steel, aluminum, copper, brass, stainless steel, and even silver, offering versatile protection for diverse components.

• What does "ESD protection" really mean in the context of this stretch film, and why is it important?

ESD protection in this film means it dissipates static charges, preventing the sudden, damaging flow of electricity that can occur when static builds up, for instance, from friction during wrapping. This is crucial because sensitive electronic components and other static-sensitive items can be seriously damaged or even destroyed by electrostatic discharge, even at low voltages.
