VFFS machines handle different films through precise temperature, tension, and sealing control. Unified Flex systems use servo-driven pull belts and digital temperature controllers to adapt to various films, from high-barrier and metalized laminations to OPP films. These adjustments maintain film tracking, sealing integrity, and consistent bag formation, even as film thickness or coating type changes.
For packaging that demands flexibility across multiple materials, Unified Flex VFFS machines provide stable, repeatable performance with every film type.
