Sachet Packing Machine——Automatic Sachet Packing Solutions for Industrial Packaging Applications
A Sachet Packing Machine is designed for automatic forming, filling, sealing, and cutting of small flexible packages used in food, pharmaceutical, cosmetic, and chemical industries. Compared with rigid packaging, sachets reduce packaging material usage, storage space, and transportation cost while maintaining efficient portion packaging for liquid, powder, granule, and paste products. At MIC Machinery, sachet packing systems are developed for stable industrial operation with reliable film feeding, accurate dosing control, and consistent heat sealing performance suitable for continuous production environments.
Working Process of Sachet Packing Machine
The packaging process starts with automatic film unwinding and tension adjustment. The packaging film passes through guide rollers and forming devices that shape the film into sachet structures according to the selected sealing type.
After pouch forming, the filling system dispenses the product into the sachet. Different dosing technologies are selected depending on product characteristics. Liquids and creams commonly use piston filling systems, while powders use auger filling mechanisms and granules use volumetric cup feeding systems.
Once filling is completed, the sealing jaws apply heat and pressure to create secure package seals. The machine then performs automatic cutting and discharge of finished sachets. Production data, sealing temperature, and packaging speed are controlled through the PLC interface to maintain stable operation.

Applications of Sachet Packing Machine
Sachet packing machines are used across multiple industries because of their flexibility and suitability for single-use packaging formats.
Food Industry
Used for packaging ketchup, coffee powder, spices, sugar, milk powder, sauces, honey, and beverage concentrates. Hygienic filling systems are essential for maintaining food safety standards.
Cosmetic Industry
Commonly used for shampoo, lotion, facial cream, conditioner, and cosmetic sample sachets designed for travel and retail packaging.
Chemical Industry
Industrial chemicals, detergents, cleaning liquids, and agricultural additives are often packaged in sachets for easier transportation and controlled dispensing.
Beverage Industry
Instant drink powders and liquid concentrates frequently use stick pack or sachet packaging for convenient consumer use.
Customization Options
Industrial packaging requirements vary depending on product viscosity, film structure, and production capacity. MIC Machinery provides customized sachet packing solutions according to factory conditions and packaging specifications.
Common customization options include:
· Servo-controlled dosing system
· Easy-tear notch device
· Date coding integration
· Automatic counting system
· CIP cleaning system
· Explosion-proof electrical configuration
· Stainless steel sanitary structure
For corrosive chemical products, the machine can also use chemically resistant pipelines and sealing materials to improve operational reliability.
Maintenance and Daily Operation
Routine maintenance is important for maintaining stable sealing quality and packaging accuracy during long production cycles. High-speed packaging systems require regular inspection of moving components and heat sealing systems.
Operators should regularly inspect:
· Sealing jaw temperature consistency
· Film tension adjustment
· Filling nozzle cleanliness
· Pneumatic system pressure
· Cutting blade wear condition
· Servo motor synchronization
· Sensor positioning accuracy
For powder packaging applications, dust accumulation around the sealing area should be cleaned regularly to maintain sealing stability. Liquid filling systems should also be flushed to prevent product residue inside the filling pipeline.Preventive maintenance schedules help reduce downtime and extend component service life in continuous industrial production environments.
