Precise pressure control is critical to achieving consistent, high-quality seals in VFFS packaging equipment. The right balance of heat, time, and pressure ensures the film layers bond evenly without distortion. Too much force can thin or wrinkle the seal, while too little pressure risks incomplete bonding or leaks. Unified Flex designs its VFFS systems with servo-regulated sealing jaws that apply uniform pressure throughout each cycle, maintaining seal integrity and minimizing leaker rates across long production runs.
