Packaging Problem Solving
Troubleshooting guides for seal failures, gauge variation, bubble instability, and other common film defects.
Diagnosing Inconsistent Seal Strength Across a Roll
When seal strength passes the test at the start of a roll and fails by the end, the cause is almost never the sealing equipment alone.
Gauge Bands: What Causes Them and How to Fix Them
Gauge bands are repeating thickness patterns around the bubble, and their repeating nature is the clue that points straight at the cause.
Seal Strength vs. Seal Integrity: What's the Difference?
A strong seal and an intact seal are not the same thing. Confusing the two is one of the most common reasons packaging fails in the field after passing every test on paper.
Why Your Film Keeps Curling on the Roll
Curl looks like a winding problem, but most of the time it starts upstream in the bubble, the gauge profile, or the resin itself.
