“Create a process FMEA for food-pouch sealing. Cover incomplete seals from low jaw temperature causing leaks, contaminated seal areas from product on the sealing surface causing lost integrity, missing lot codes from empty ink supply, and skewed pouches from an out-of-position guide rail causing wrinkled seals. Include temperature, fill-volume, seal-strength, vision, camera and operator-inspection controls.”
看懂背後的決策。
Lock the setpoint and verify seal strength.
Keep product away from the sealing surface.
Use a camera to confirm each lot code.
Inspect guides that keep the pouch square to the jaws.
Use this PFMEA for a heat-sealed pouch process and adapt it to the actual film, product and inspection method.
常見問題
What is a pouch-sealing PFMEA?
It is a process FMEA that evaluates sealing, coding and handling steps for failure modes that affect package quality.
Why test seal strength?
A seal-strength test can detect weak or incomplete seals before product is distributed.
What is a prevention control for seal contamination?
A fill-volume control can reduce the chance that product reaches the sealing surface.
