A stick pack filling machine is a specialised form-fill-seal machine that produces narrow, tube-shaped single-serve sachets called "stick packs." The machine forms a narrow tube from a roll of flat film, fills it with a small amount of powder (typically 1–30g), and seals the top and bottom. Stick packs are used for single-serve portions of sugar, coffee, protein powder, seasoning, pharmaceutical sachets, and condiment powders. The stick format (typically 25–35mm wide, 100–150mm tall) is compact, convenient and popular in food service and e-commerce.

Speed depends on the number of lanes and fill weight. A single-lane stick pack machine produces 80–200 sticks/min for 2–10g fills. A 4-lane machine produces 320–800 sticks/min total. A 10-lane high-speed machine achieves 800–2,000 sticks/min, equivalent to 48,000–120,000 sticks/hour — suitable for mass-market coffee, sugar or pharmaceutical sachets. The practical speed limit is the sealing dwell time (longer dwell = lower speed); fast-sealing films and servo drives enable maximum throughput.

Best-suited powders: free-flowing powders with consistent density — sugar, salt, instant coffee, protein powder, powdered milk, powdered seasoning, effervescent vitamin powder, pharmaceutical sachet powders (ORS, antacids, pain relief powders). Challenging powders: very hygroscopic powders (maltodextrin, powdered drink mixes) require humidity-controlled environments and rapid sealing; cohesive or oily powders may bridge in the narrow fill tube. For challenging powders, a vibration-assisted fill tube or heated fill section is available.

Compatible stick pack films: PE/PE laminate (basic barrier, low cost), PET/PE (improved barrier for moisture-sensitive products), foil/PE or foil/CPP (high barrier for pharmaceutical and hygroscopic products), BOPP/PE (transparent window packs for retail display), kraft paper/PE (sustainable packaging option). Film width per lane: 40–120mm depending on stick width. Most machines accept standard roll stock with 76mm or 152mm core.

Yes. Pharmaceutical-grade stick pack machines are available with GMP-compliant design: sealed fill chamber to prevent contamination, validated servo dosing for precise fill weights (±0.5–1%), HEPA-filtered air purge, 316L stainless steel contact surfaces, 21 CFR Part 11 compliant data recording, and full audit trail. For regulated pharmaceutical stick packs (ORS sachets, pain relief powders, pharmaceutical nutritional supplements), our engineers can provide IQ/OQ/PQ validation documentation support.

A single-lane stick pack machine with auger dosing (1–30g): from $25,000–$55,000 USD. 4-lane machine for mass-market production: $80,000–$150,000 USD. 10-lane high-speed system with nitrogen flush and quality inspection: $180,000–$350,000 USD. Pharmaceutical-grade single-lane with GMP documentation: $60,000–$120,000 USD. Contact us with your product, fill weight, stick dimensions and daily production target for a free quotation.
