A stick pack machine is a multi-lane vertical sachet machine: each lane forms, fills and seals one narrow stick per cycle from a single roll of film. Machines commonly run 1 to 12 lanes; total output scales with lane count and cycle rate, so an 8-lane machine at typical cycle rates delivers several hundred sticks per minute. Choosing comes down to product system (auger for powders, liquid piston for sauces), laminate compatibility and changeover scope.
What a stick pack is
Stick packs are narrow single-serve sachets — sugar, coffee, drink mixes, pharmaceutical powders — typically sealed on all four ends. Their narrow geometry multiplies nicely: one machine, many lanes, one film roll. The format dominates wherever single-dose portability matters more than per-unit material cost.
Lanes and output
| Lanes | Typical use | Output behavior |
|---|---|---|
| 1-2 | Pilot lines, pharma validation | Tens of sticks/min |
| 4-6 | Mid-volume food and supplement | Scales linearly with lanes |
| 8-12+ | Commodity sugar, coffee, drink mixes | Several hundred/min at typical cycle rates |
Output figures are product- and film-dependent; treat any headline rate as unverified until demonstrated on your material.
Buy lanes for your fastest SKU, not your average one — lane count is fixed at build time while filling systems can be upgraded. And verify film supplier lead times before committing to a laminate spec.
Filling systems by product
Free-flowing powders use augers with servo dose control; granules can run volumetric cups; liquids and gels use piston fillers with suck-back to keep seal areas clean. Seal integrity on narrow sticks is unforgiving — product contamination in the seal zone is the top reject cause, so filling precision directly drives packing yield.
Frequently Asked Questions
How many lanes should a stick pack machine have?
Match lanes to your highest-volume SKU: lanes multiply output but are fixed at build. Producers commonly start at 4-6 lanes for mid-volume SKUs and specify 8-12 for commodity single-serves.
What products run on stick pack machines?
Powders dominate — sugar, sweeteners, instant coffee, supplements, pharma sachets. Liquids like honey, sauces and gels run on piston-filled variants with clean-cut seal design.
Stick pack vs sachet — what is the difference?
Stick packs are long, narrow, single-dose tubes; sachets are wider flat packets. Both run on multi-lane vertical machines, but tooling, film width and filling optics differ.
