The performance of a VFFS machine depends on several core assemblies that work together to form, fill, and seal each package. Critical components include the pulling belts, which control film feed and tension; the forming collar and tube, which shape the bag; and the sealing jaws, which ensure airtight seals. Regular inspection of these parts and calibration of temperature and pressure settings are essential to maintaining consistent output.
Unified Flex machines feature servo-controlled pulling belts and precision-engineered forming sets that provide smooth film movement and reliable sealing. This design minimizes wear over time and supports repeatable, high-quality performance across every production run.
