FAQ

Can I run both thin gauge (15-20 micron) and heavy-duty (150 micron) film on the same film blowing machine?

2026-04-29
The Short Answer:
Yes, it is possible. However, the "process window" to do this reliably on a single film blowing machine is narrower than many buyers realize.

The Technical Challenge:

Running thin gauge film (like 15-20 micron garment bags) requires high haul-off speeds and tight die gap settings. Conversely, heavy-duty film (like 150 micron construction film or heavy bags) needs a slower haul-off and higher output to prevent the melt from sagging.

Adjustable die gap on spiral die head for blowing 15-150 micron film

Our Engineering Advice for Dual-Range Operation:

To handle this 15-150 micron span without changing the die head every day, your machine must have:

Adjustable Die Gap: Manual or motorized lip adjustment is a must.

Wide Haul-off Range: A speed span of at least 8:1.

Flexible Air Ring: Variable airflow to stabilize different bubble sizes.

Pro Tip from Yuexing: Expect a 30–45 minute changeover time when switching between these extremes. You'll need a short trial run to stabilize the process before you hit "sellable" film quality.
