Continuous and intermittent VFFS machines differ mainly in how the film moves during sealing. Continuous-motion machines keep the film advancing while sealing occurs, providing higher throughput for lightweight or free-flowing products. Intermittent systems pause the film for each seal, offering greater control and precision for heavier fills or complex bag styles.
Unified Flex engineers both motion types with application-specific performance in mind, helping manufacturers select a VFFS configuration that strikes the optimal balance of speed, precision, and seal quality for their product and production objectives.
