Customer equipment selection guide

Stick pack filling machines

Narrow flexible packs for single-dose powders, granules and selected liquids.

Where this equipment or process fits

Narrow flexible packs for single-dose powders, granules and selected liquids. The product name alone is not enough to select machinery: viscosity, particles, foam, temperature, aeration, chemical compatibility and pack tolerance can change the correct solution.

Applications to investigate

  • drink powders
  • sweeteners
  • supplements
  • single-dose liquids

Issues to challenge in a trial

  • bridging in narrow tubes
  • static powder
  • seal contamination
  • stick counting

Build the specification around sustained production

Record the complete dose range, product condition at the point of filling, container and closure drawings, real samples, intended labels, target output and every planned recipe or pack change. State whether output is a maximum instantaneous speed or a sustained sellable rate after refilling, minor stops, rejects and operator intervention.

Review the full process rather than the filler in isolation. Container preparation, feeding, dosing, filling, capping or sealing, labelling, coding, inspection, reject handling, conveying, accumulation and secondary packaging can each become the bottleneck. The layout also needs guards, maintenance access, cleaning access, utilities, raw-material movement and finished-goods movement.

Use representative samples and measurable acceptance criteria

A useful machinery trial challenges the difficult edges of the requirement: minimum and maximum dose, warmest and coldest product, largest expected particles, highest foam risk and packs from more than one supplier batch. Record settings, output, accuracy or presentation results, cleaning observations and open points. Those results should feed into a written factory acceptance test.

Common questions

What applications should be considered for stick pack filling machines?

The strongest starting applications include drink powders, sweeteners, supplements and single-dose liquids. The final choice still depends on a representative product and pack trial.

What information is needed to specify stick pack filling machines?

Provide product behaviour at the real filling temperature, minimum and maximum dose, target sustained output, container and closure samples, cleaning method, utilities and available space.

What should be tested before equipment is ordered?

Test bridging in narrow tubes, static powder, seal contamination and stick counting, together with achievable output, repeatability, changeover and cleaning.

Should the complete packaging line be reviewed?

Yes. Container preparation, filling, closing, labelling, coding, inspection, reject handling and accumulation need to work as one balanced process.

Can the equipment be expanded later?

Often it can, but future container formats, nozzle pitch, conveyor height, controls, guarding and upstream or downstream automation should be considered during the first specification.
