What commonly causes this problem with stick packs?

Common causes include operators waiting to load, position or remove packs; A change in film or pouch dimensions or opening and presentation.; the machine being starved by a small hopper, feeder or upstream process.

How can I prove that an adjustment has worked for stick packs?

Record a representative baseline, change one variable at a time and repeat the same measurement over enough packs to show that the result is stable rather than a one-off improvement.

When should I consider a different machine or production method for stick packs?

Consider a different route when correct setup and maintenance cannot hold the required quality and sustained output across the complete product and pack range.

What information should I send before asking for a solution for stick packs?

Include Production film or pouches; Material and seal-layer data; Minimum and maximum pack size; Product sample and target dose.

Which solution website is most relevant to this question?

The clearest starting point on this page is Pouch Fillers. Final suitability still needs to be confirmed using the actual product, packaging, output and site information.

Flexible packaging

Why is stick packs running too slowly?

Practical guidance for stick packs: separate true machine speed from waiting, handling, replenishment and short stops.

Answer format: direct explanation, ordered checks and relevant solution routes. Updated 4 August 2026. Application-specific engineering review is still required.

Direct answer

For stick packs, measure sustained good output over a representative run rather than relying on the machine’s maximum cycle rate. Flexible packaging combines product dosing with film or pouch handling and controlled heat, pressure, dwell and cooling. Start by count good packs over at least one representative production period and record dose distribution, seal strength, leak rate, film waste and sustained packs per minute. Make one controlled change at a time so the original cause is not hidden by several new settings.

Production environment relevant to flexible packaging

Work safely: Isolate machinery before inspection or clearing. Follow the machine manual, site procedures and competent-person requirements.

What usually causes this?

operators waiting to load, position or remove packs
A change in film or pouch dimensions or opening and presentation.
the machine being starved by a small hopper, feeder or upstream process
The equipment or handling method not being set for narrow single-dose packs for powders, granules or liquids.
short stops and resets consuming more time than expected

Checks to make in order

Count good packs over at least one representative production period
Record dose distribution, seal strength, leak rate, film waste and sustained packs per minute using a representative sample.
Record running, starved, blocked and fault time separately
Check dose timing and product drop, seal cleanliness, heat, pressure and dwell and pack support through discharge and cooling.
Measure loading, replenishment and changeover time
Identify the operation with the longest effective cycle
Test one improvement and confirm the bottleneck moves

How to decide the next step

Stick packs involves narrow single-dose packs for powders, granules or liquids. Increase speed only after the limiting step and the required buffer or operator method are clear.

If adjustment and maintenance cannot hold the required result across the complete product and pack range, compare the machinery route against a written acceptance test. The important comparison is sustained good output—not only maximum cycle speed.

What to include in your production brief

Supplying the information below makes it much easier to distinguish a setup problem from a machinery or packaging limitation:

Production film or pouches
Material and seal-layer data
Minimum and maximum pack size
Product sample and target dose
Seal acceptance test
Required output and coding
Samples that represent stick packs
A short video of the current process and fault

Relevant solution websites

These specialist sites match the production process discussed above. Final suitability should be confirmed with samples, output, site and acceptance information.
