• Residential building wire insulation
• Low-voltage automotive cables
• Halogen-free data/signal cables
• Flexible appliance cords and sheathing

4. Flexible Film Manufacturing

Film manufacturers utilize Ateva 9030 EVA for blown and cast film applications demanding clarity, puncture resistance, and low seal initiation temperature. This grade allows tailored film gauge and mechanical property control in formulations replacing or modifying polyolefin resins. Film lines employ it in agricultural film, industrial liners, and stretch wrap, where uniform melt behavior and low blocking are essential for consistent downstream conversion.
