Packaging powders and granules—from milk powder and spices to seeds and plastic pellets—presents unique challenges of dust containment, precise dosing, and maintaining product integrity. Dust escape creates safety hazards, contaminates the production line, and leads to costly material loss. Inaccurate filling results in giveaway or underweight packages, directly impacting compliance and profitability. Furthermore, materials range from free-flowing to cohesive, and some are hygroscopic, requiring careful handling to prevent caking or degradation during the packaging process.

Selecting the right technology path is critical. For most free-flowing granules and powders, a Vertical Form-Fill-Seal (VFFS) machine with a fully enclosed dust-proof design and a screw or net-weight dosing system provides excellent accuracy and containment. For premium, high-barrier packaging or challenging, aerated powders, a premade pouch filling system offers superior seal integrity and can handle complex bag structures. The choice between a net weight scale (for top accuracy) and a volumetric screw filler (for speed and cost) depends on your product value and required dosing tolerance.
