PACKAGING PERFORMANCE AND SEAL INTEGRITY
Seal defects are usually a system problem—not only a temperature problem.
Product contamination, film properties, jaw condition, pressure, dwell time, temperature distribution, tension, tracking and machine timing interact. FFT Services evaluates the complete packaging window to identify root causes and establish stable operating conditions.
Support covers recurring leaks, open seals, wrinkles, burn-through, poor peel, film misalignment, weight variation, slow cycles, changeover loss and excessive packaging waste.
CONNECTED ENGINEERING SUPPORT
Where FFT Services can add practical value
Technical diagnosis and improvement for thermoforming, VFFS, HFFS, filling and sealing systems affected by leakage, rejects, downtime or unstable quality.
Film and product interaction
Review film structure, thickness, storage, product temperature, moisture, oil and seal-area cleanliness.
Mechanical condition
Inspect jaws, anvils, alignment, parallelism, pressure, bearings, heaters and cooling.
Process parameters
Measure temperature distribution, time, pressure, speed, tension, vacuum and timing.
Capacity and waste
Analyse cycle losses, stops, rework, giveaway, trim and film consumption.
Stable operating window
Define settings, inspection methods, limits, reaction plans and verification frequency.

FREQUENTLY ASKED QUESTIONS
Before starting the assessment
Can you diagnose intermittent seal leakage?
Yes. Intermittent defects require correlation of samples with film position, product contamination, temperature zones, pressure, timing and machine cycles.
Do you test packaging film?
Relevant supplier data and factory tests can be reviewed. Specialised laboratory testing may be recommended through an appropriate external laboratory when required.
Can improvement include new sealing jaws or change parts?
Yes. Repair, redesign, alternative materials, new tools or equipment modification can be evaluated after the cause is established.
