Powder is one of the most demanding materials to package. Fine particles can drift, cling to equipment surfaces, and settle unevenly inside a bag. Methods that work well for whole grains or snack products do not always suit it.
Powder is one of the most demanding materials to package. Fine particles can drift, cling to equipment surfaces, and settle unevenly inside a bag. Methods that work well for whole grains or snack products do not always suit it.
For food, chemical, and pharmaceutical manufacturers, the packaging line is the final stage of a long production process. Inefficiencies at this point lead to product waste, rework, and delays. The choice of machine, bag format, and weighing method therefore has a direct effect on output and consistency.
This blog explains how a powder packaging line operates, which equipment BORCH Packaging offers for it, and which specifications to compare before selecting a machine.
What a Powder Packaging Line Needs to Do
Most lines handle the same core jobs in the same order. The BC-VFS740 vertical machine shows the sequence well, because it combines bag making, weighing, filling, degassing, sealing, printing, and counting in one unit.
In simple terms, a line needs to:
- Form or pick up the bag
- Meter the right weight of powder
- Fill the bag and remove excess air
- Seal it, print a code, and count the output
After the filler, many plants add check weighing, labeling, coding, and palletizing. The BORCH range covers these steps too, so a buyer can plan the full line with one supplier.
Powder Packing Machines from BORCH Packaging
BORCH does not sell a single powder machine. It offers a few formats, and the right one depends on bag type, weight, and speed.
1.GD Premade Pouch Filling Machines
The GD series fills ready-made pouches. Paired with a metering discharge system, it can pack granules, liquids, powders, and pastes automatically. It handles stand-up pouches, zipper bags, three-side sealed bags, four-side sealed bags, and back-sealed bags, among others.
Key specifications for the GD260:
- Siemens PLC control and a 7-inch LCD touch screen
- Pouch weight from 40 to 1,000 g
- Accuracy of ±0.2%
- Speed of 20 to 50 bags per minute
- Pouch width of 80 to 200 mm and length of 100 to 300 mm
- Automatic detection of unopened pouches
- A variable frequency speed regulation device
2.BC-VFS740 Fully Automatic Packaging Machine
This vertical form-fill-seal machine makes the bag from film and fills it in one pass. Its product page lists powders among the materials it suits, along with food, seeds, and granules.
- Package weights from 0.1 to 5 kg
- Accuracy of ±1 g
- Up to 40 bags per minute without vacuum, and 20 with vacuum
- Servo motors drive both the horizontal and vertical sealing
- A 10-inch widescreen HMI
- Core parts made of 304 stainless steel
- IoT functionality
3.Semi-Automatic Auger Filling for Chemical Powders
Not every plant needs a fully automatic line. BORCH shows a semi-automatic machine with automatic sewing, used for polyacrylamide and described as suitable for chemical powders and granules. It uses auger filling and a load cell. An operator bags by hand, then the machine clamps, fills, and sews the bag shut.
BORCH also lists a Lifting Powder Metering Scale in its filling systems range. This is worth asking about if you want a powder-specific weighing option.
Which Bag Formats Work for Powder?
Format drives machine choice, so it helps to match the pack size to the right equipment. These formats from the BORCH solutions range fit powder products:
- 3-side seal sachet: 1 to 50 g, a single-dose pack listed for sauces, powders, and condiments
- 4-side seal or stick pack: 5 to 100 g, listed for powder, granules, and liquids
- Bag-in-bag: 5 to 25 kg, listed for flour, sugar, and salt
- Ton bag (FIBC): 500 kg to 2 t, filled with the D1000 bulk bag scale, listed for resin, fertilizer, and grain
Small sachets and stick packs suit consumer or single-dose products. The bag-in-bag and bulk formats suit heavier industrial output.
Which Industries Use These Machines?
BORCH Packaging works with a wide range of industries. The ones most relevant to powder include:
- Food processing
- Chemicals
- Flour
- Sugar
- Salt
- Detergent powder
- Coffee and tea
Food and chemical powders are well covered by the examples above. Pharmaceutical use is shown more narrowly. Pharmaceuticals are among its main application industries, with Chinese herbal medicine pieces as a typical material. These scales weigh granular, block, and sheet materials from 20 to 1,500 g at up to 120 packs per minute.
They are not a powder filler, so pharmaceutical powder buyers should talk with BORCH about their exact product before choosing equipment.
Equipment That Completes the Line
A filler is only one part of the job. BORCH lists supporting machines that finish the line:
- Checkweigher and barcode scanner with rejector for inspection.
- Thermal transfer printer and labeler for coding and marking.
- Heat sealer for closing bags.
- GKS-232D heat sealing sewing machine for 3-layer flat paper bags with a PE film liner, running up to 10 m per minute.
- Z bucket elevator with a 1.8 L hopper and a 304 stainless steel body, with carbon steel as an option.
- Conveyors for moving packs between stations.
- Palletizing robots from ABB and ESTUN, with a load range of 110 kg and 120 kg, respectively.
BORCH lists its palletizing robot as stacking bags and bottles at up to 2,000 units per hour.
What to Compare Before You Choose
A few specifications decide most purchases. Check these against your own product:
- Bag type and size: Pouch, sachet, stick pack, or sewn bag.
- Weight range: A 40 g pouch and a 25 kg bag need different machines.
- Speed: Bags per minute, with or without vacuum.
- Accuracy: ±0.2% on the GD260 and ±1 g on the VFS740.
- Contact materials: 304 stainless steel in core parts is listed on several BORCH machines.
- Automation level: Fully automatic or semi-automatic with hand bagging.

Summary
Powder packing works best when the machine, bag, and weighing method are chosen together. BORCH Packaging offers premade pouch fillers, a vertical form-fill-seal machine, and semi-automatic auger filling for chemical powders.
Sachet and stick pack formats cover small doses, while bag-in-bag and bulk formats handle heavy loads. Inspection, coding, and palletizing equipment completes the line.
Food and chemical powders are clearly covered in the range. Pharmaceutical needs call for a closer conversation about the product itself.
