When it comes to vertical packaging machines, they can be categorized in multiple ways—by product state (liquid, powder, granular), packaging function (inner/outer packaging), industry application (food, daily chemicals, hardware), and automation level (fully automatic, semi-automatic). Today, we’ll focus on classification by product form, which includes granular, liquid, and powder packaging machines.
For businesses exploring packaging solutions for the first time, this breakdown helps clarify key differences. A common question we receive is:
❓ Can one machine handle both granules and liquids?
❓ Is it possible to package powders and liquids with the same equipment?
The answer is no, and here’s why.
How Packaging Machines Differ by Product Type
The primary distinction lies in the measuring method used for different product forms. Let’s examine each type in detail.
1. Granule Packaging Machines
Applications:
✔ Potato chips, peanuts, nuts, sunflower seeds
✔ Rice, quinoa, dried fruits
✔ Hardware items (screws, nails, fasteners)
Measuring Methods:
-
Combination weigher (for high-speed, high-precision weighing)
-
Linear weigher (for uniform product distribution)
-
Measuring cups (for consistent portion control)
Selection Factors:
-
Particle size, weight, and shape
-
Special requirements (e.g., fragile or irregularly shaped items)

2. Liquid Packaging Machines
Applications:
✔ Edible liquids (oil, honey, sauces, dressings)
✔ Cosmetics & chemicals (shampoo, lotions, detergents)
✔ Viscous products (cream, paste, syrup)
Measuring & Filling Methods:
-
Piston pumps (for precise liquid dispensing)
-
Peristaltic pumps (for shear-sensitive liquids)
-
Gravity filling (for free-flowing liquids)
Optional Features:
-
Stirring function (to prevent settling)
-
Heating system (for thick or crystallizing liquids)
-
Anti-drip nozzles (to minimize waste)
3. Powder Packaging Machines
Applications:
✔ Food industry (coffee, flour, spices, protein powder)
✔ Pharmaceuticals (medicinal powders, supplements)
✔ Industrial powders (detergents, pigments, chemicals)
Measuring Mechanism:
-
Auger screw filling (ensures precise, consistent dosing)
-
Vibratory feeders (for free-flowing powders)
-
Weight-based filling (for ultra-high accuracy)
Customization Options:
-
Screw size & pitch adjustments
-
Dust extraction systems (for hygiene & safety)
-
Anti-caking mechanisms (for clumpy powders)
Key Takeaway
While the main packaging unit (forming, sealing, cutting) may be similar across machines, the measuring system varies significantly:
-
Granules → Weighing scales
-
Liquids → Pump-based dispensing
-
Powders → Screw metering
