Sachet Filling Machine——Automatic Sachet Filling Solutions for Liquid, Powder, and Granule Packaging
A Sachet Filling Machine is designed for high-speed packaging of small-dose products into flexible sachets used in food, cosmetic, and chemical industries. Compared with rigid packaging, sachets reduce packaging material consumption and transportation cost while improving convenience for single-use applications. At MIC Machinery, sachet filling systems are developed for stable industrial operation with reliable sealing performance, accurate dosing control, and flexible configurations for liquid, paste, powder, and granule packaging applications.
Working Process of Sachet Filling Machine
The packaging process begins with automatic film unwinding. The packaging film passes through tension control rollers to maintain stable positioning during operation. Depending on the sachet type, the machine forms the pouch through vertical or horizontal sealing systems.
After pouch forming, the dosing system fills the product into the sachet. Different filling methods are selected according to product characteristics. Liquid products commonly use piston pumps or flow meter systems, while powders use auger filling systems and granules use volumetric cup dosing.
The machine automatically performs sealing after filling. Heat sealing temperature and pressure are controlled through the PLC system to maintain seal consistency. Finished sachets are then cut and discharged through the conveyor system for secondary packaging or carton packing.

Applications of Sachet Filling Machine
Sachet packaging is widely used because of its low packaging cost, portability, and suitability for single-use products. Different industries require different filling and sealing configurations depending on product properties.
Food Industry
Used for ketchup, sauces, coffee powder, sugar, spices, milk powder, honey, and instant beverage products. Hygienic filling systems are important for food safety compliance.
Cosmetic Industry
Widely used for shampoo, facial cream, lotion, conditioner, and cosmetic sample packaging. Small sachet packaging improves convenience for travel and retail distribution.
Chemical Industry
Used for detergents, cleaning liquids, industrial additives, and agricultural chemicals where flexible low-volume packaging is required.
Customization Options
Different products and packaging materials require customized machine structures and dosing systems. MIC Machinery provides flexible configuration options according to production requirements and factory layout.
Common customization options include:
· Single-lane or multi-lane production
· Servo-driven dosing systems
· Automatic film tracking system
· Nitrogen flushing function
· Easy-tear notch design
· Date coding and batch printing
· Stainless steel hygienic structure
· CIP cleaning system
· Explosion-proof electrical configuration
· Automatic counting and carton packing integration
For corrosive or aggressive chemical products, the machine can also use special sealing materials and chemically resistant filling pipelines.
Maintenance and Daily Operation
Routine maintenance is important for maintaining sealing consistency and filling accuracy during long production cycles. Sachet packaging machines operate at high speed, so regular inspection reduces downtime and improves equipment reliability.
Operators should regularly inspect:
· Sealing jaw temperature stability
· Film tension adjustment
· Filling nozzle cleanliness
· Pneumatic pressure condition
· Cutting blade wear
· Sensor positioning accuracy
· PLC alarm records
For powder products, cleaning is especially important to prevent dust accumulation around the sealing area. Liquid filling systems should also be flushed regularly to prevent residue buildup inside the pipeline.Preventive maintenance schedules help extend component life and maintain stable production efficiency.
FAQ
1）Can the machine produce different sachet styles?
Yes. The machine can support back seal, three-side seal, and four-side seal sachets depending on the packaging design.
2）Can the machine work with laminated film?
Yes. Most industrial sachet filling machines are compatible with laminated film materials including PET/PE and aluminum film structures.
3）Is automatic coding available?
Yes. Date coding, batch coding, and printing systems can be integrated into the machine.
