Stop guessing and start sealing. The ultimate engineering guide to calibrating temperature, pressure, and dwell time for flexible pouches.
Expert Engineering Insight
"In my 14 years in packaging design, I’ve seen countless brands struggle with leaky seals simply because of incorrect temperature settings. There is no 'one size fits all' temperature because it depends entirely on the machine (roller vs. impulse) and the material thickness (e.g., 80 microns vs. 120 microns)."
"For our standard industrial roller sealing machines, we typically establish a baseline of 3 seconds / 40psi / 160°C. But before running a full batch, I always require my team to perform the 'Strip Test' to avoid wasting expensive printed stock."
