A powder packaging machine is a type of automatic quantitative packaging equipment designed for small-sachet packaging across industries such as pharmaceuticals, food, chemicals, and pesticides. This equipment is primarily used for the automated packaging of fine granular products, including granular medicines, sugar, coffee, powdered drink mixes, tea, MSG, salt, seeds, and desiccants. In 2025, Hainan Yangxing Biotechnology Co., Ltd. obtained a patent for a "vertical powder packaging machine."
These machines typically employ a volumetric cup-based metering system and utilize a three-side seal method for bag formation. Based on metering principles, they are broadly categorized into auger-type and weight-based systems; the weight-based variant utilizes high-precision sensors for real-time weighing feedback control, offering superior accuracy. Compatible packaging materials include composites such as PP/PE, PET/Al/PE, PET/VMPET/PE, and Nylon/PE. Advanced technologies, such as bottom-filling systems-where the filling nozzle is positioned at the base of the bag to minimize dust generation-have also been developed. Fully automated packaging lines integrate multiple units-including automatic bag feeding, metering and filling, vacuuming, sealing, inspection, and palletizing-to achieve complete automation from raw powder to boxed finished products.
