In brief
Plan practical seal-integrity checks for induction foils, pouches, sachets, films, caps and tamper-evident packaging. Use a written requirement and compare the complete installed operating scope, not a headline specification or purchase price in isolation.
Define the failure the seal must prevent
Leakage, moisture, oxygen, contamination, opening and tamper evidence need different tests and acceptance limits.
Control the sealing window
Temperature or energy, pressure, dwell time, line speed, contamination and material variation determine seal formation.
Use challenge samples and storage
Immediate visual checks can miss channels or weak adhesion. Include peel, leak, burst, vacuum, dye, transport or shelf-life tests as appropriate.
Link inspection to rejection
Where seal presence or quality is automatically inspected, define detection capability, false rejects, challenge frequency and fail-safe behaviour.
