Professional Powder Sachet Machine

An auger filler uses a servo-motor-driven screw to push a precisely controlled volume of powder into each pouch. Because the screw speed, pitch, and rotation count are all digitally controlled, filling accuracy reaches 99.9% — even for powders that are sticky, cohesive, or vary in bulk density batch to batch. A volumetric cup filler, by contrast, relies on a fixed cavity size. Any variation in powder density or moisture content directly causes weight error. For expensive materials like probiotics or pharmaceutical powder, auger filling pays for itself quickly in reduced giveaway alone.

Yes. The servo-driven auger adapts to a wide range of powder flowability characteristics. Free-flowing powders (salt, sugar, instant coffee) run at full speed. Non-free-flowing or cohesive powders (milk powder, probiotic powder, certain pesticide powders) may require an agitator attachment or adjusted auger pitch — both are configurable options. Share your material’s bulk density and particle size when enquiring and we will confirm the right configuration.

Standard output is a back-seal (pillow-style) pouch with optional round corners. Bag length range: 50–180 mm. Bag width range: 50–280 mm. Optional add-ons include perforation, easy-tear notch, exhaust valve, and custom-shaped pouch dies. Round-corner punching is the most popular upgrade for brands positioning in food, health supplement, and cosmetic powder categories.

The machine is compatible with most common laminated packaging films: BOPP/PE, NY/PE, PET/AL/PE (aluminium foil laminate), and kraft paper composites. For moisture-sensitive powders like milk powder or probiotic powder, we recommend a high-barrier AL foil laminate. For pesticide powder packaging, consult your film supplier for chemical-resistance ratings. We can advise on film thickness and sealing temperature ranges during machine commissioning.

This is the most critical design challenge in powder sachet packaging — and the core reason we built the 夹拉背边封 (back-seal) structure the way we did. Three mechanisms work together:

(1) a controlled powder drop that minimises airborne dispersion during filling;

(2) a back-seal jaw geometry that clamps the film before powder can migrate to the seam;

(3) an optional dust-purge air knife that clears residual particles from the seal zone before heat is applied. The result is a 100% airtight seal on every pouch — even with fine, light powders that are notorious for seal contamination.

Almost certainly yes. Pesticide powder leakage typically has one of three root causes:

(a) powder migrating to the seal zone before sealing,

(b) insufficient seal temperature or dwell time for the film laminate, or

(c) incorrect auger speed creating pressure surges during filling. Our machine addresses all three: the sealed filling chamber, adjustable seal temperature (range configurable per film spec), and servo-controlled auger speed eliminate the most common failure modes. We have a specific case study on this — ask our team for the Pesticide Powder Packaging application report.

Yes, and this is one of its strongest application areas. The key is the combination of high-barrier film compatibility, airtight back-seal closure, and optional nitrogen-flush or exhaust valve add-ons. Nitrogen flushing replaces oxygen inside the pouch before sealing, dramatically extending shelf life for oxidation-sensitive materials like probiotic powder and vitamin supplements. Please specify if nitrogen flushing is required at the time of ordering.

The rated speed is 10–50 bag/min, but actual throughput depends on your powder’s flowability, pouch size, and fill weight. As a general guide: free-flowing fine powders (instant coffee, seasoning) at small bag sizes (10–15 g) typically run at 40–50 bag/min. Cohesive or sticky powders at larger fill weights (80–100 g) are more typically 15–25 bag/min. We always recommend a material trial before confirming your expected output rate — contact us with your target bag size and fill weight for a realistic estimate.

Parameter changeover (fill weight, bag length, seal temperature) is done through the PLC touchscreen and takes under 5 minutes. Physical changeover — changing bag width, swapping auger screws for a different powder type, or changing the round-corner punch die — typically takes 20–40 minutes with a trained operator. We provide a full changeover checklist and on-site training during commissioning.

All product-contact parts are made from 304 stainless steel or food-grade materials. The machine design is compatible with GMP (Good Manufacturing Practice) guidelines for pharmaceutical powder packaging and food-grade standards for milk powder, protein powder, and seasoning. If your facility requires specific material certifications (e.g., FDA-compliant contact materials), please advise at the quotation stage and we will provide documentation.

The auger filler assembly is designed for tool-free disassembly: the hopper, auger screw, and filling tube can be removed and cleaned in under 15 minutes. For facilities running food-grade and chemical (e.g., pesticide powder) products on separate lines, we strongly recommend dedicated machines — cross-contamination risk is a regulatory and liability issue that no cleaning protocol fully eliminates. For single-category lines, a dry-brush clean followed by an air purge between batches is sufficient for most powders.

Every machine ships with: the base packing unit, PLC touchscreen controller, one set of auger screws matched to your specified fill weight range, standard back-seal tooling, electrical connection guide, operation manual (English + Chinese), and a spare parts kit covering the most common wear items (sealing elements, sensors, belts). Optional extras — round-corner punch die, nitrogen flush kit, date coder, conveyor — are quoted separately.

Yes. Send us 2–3 kg of your powder material, your target fill weight, and your preferred bag size. Our technicians will run a filling trial on the appropriate model, record accuracy data and speed, and send you sample pouches along with a test report. There is no charge for the material trial — it is part of our standard pre-sales process for powder sachet filling machines.

We offer remote support via video call for troubleshooting and parameter adjustment — most issues are resolved within 24 hours. On-site commissioning and operator training is included for orders within our standard service regions. Spare parts are stocked and dispatched within 48 hours. For international customers, we provide a recommended local service partner list and can arrange extended warranty options on request.
