Seal failures in VFFS packaging often occur due to contamination in the seal area, improper heat settings, or uneven sealing pressure. Even small particles trapped between film layers can lead to weak seals and leaks after packaging. Unified Flex addresses these issues through servo-controlled sealing jaws and digital temperature control systems that maintain consistent sealing conditions. Additionally, optional nitrogen or air-flush systems help displace oxygen within the package, reducing oxidation and helping preserve product freshness while maintaining a clean sealing environment.
