4 Side Seal Sachet Packaging Machines Comparison Points
Compared with the common three-side seal or back seal packaging machines on the market, the 4 side seal sachet packaging machines has significant advantages in the symmetry and stability of the packaging structure. As the four sides are independent of the pressure and temperature control, the equipment produced by the packaging bag edge flat, no wrinkles, and the compressive strength than similar products by more than 30%. This highly symmetrical visual presentation not only improves the grade of the end product, but also makes it have a higher pass rate on the automatic packaging production line.
In terms of performance, this product uses a multi-axis servo system to replace the traditional mechanical cam structure. This means that the 4 side seal sachet packaging machines can realize full digital synchronization from film pulling, sealing to cutting, and control the positioning error within ± 0.2mm. Compared with the physical vibration and mechanical wear of traditional equipment during high-speed operation, this equipment reduces the failure rate by about 40% while increasing the production speed by 50%, ensuring the stability of continuous mass production.
High-pressure Airtight Packaging Technology

In view of the risk of easy leakage of liquid and paste in transportation, the constant pressure heat sealing of 1.5MPa with balanced stress on all sides ensures that the packaging bag does not leak under the negative pressure environment of 0.08MPa, thus ensuring the long-term shelf life.
Multi-axis Servo Precision Metering System

Aiming at the problem of uneven filling of medicine and high-value powder, a spiral or piston pump with 0.01g precision is used to reduce the metering error from 3% to less than 1% commonly used in the industry, thus eliminating material waste.
Intelligent Photoelectric Automatic Deflection Correction Function

To address the deflection phenomenon that is easily caused when replacing the roll film and starting up, the system corrects the position in real time through a high-speed color scale sensor, reducing the first bag waste rate by 95% and significantly saving the high cost of composite film packaging materials.
Modular GMP Hygienic Architecture

Aiming at the cross-contamination pain points during multi-category switching, a fully open 304 stainless steel frame and quick disassembly filling parts are adopted to shorten the cleaning and disinfection time of core components from 2 hours to 25 minutes.

FAQ
A1: extremely flexible, by changing the filling device (such as screw filling, volume cup filling or piston pump), can handle powder, granules, sauce and water liquid and other forms of materials.
A2: Yes. The machine is equipped with precision tension control system and adjustable sealing pressure device, which is suitable for aluminum foil, paper plastic or pure plastic composite film with different thickness from 50μm to 150μm.
A3: We use double temperature control PID system and cross mesh sealing mold to apply uniform pressure up to 5kg/cm², and ensure the sealing integrity of each 1 package through the air tightness detection module.
A4: With a modular former design, by changing the forming kit and adjusting the parameters from the HMI, the entire changing process can usually be completed within 20-30 minutes.
A5: The machine uses servo drive to replace most mechanical cams, and the noise level is controlled below 75dB, which is far lower than the industry average of 85dB, suitable for various production environments.
A6: It is recommended to clean the key parts once a week and check the air pressure seal every month. Thanks to the use of self-lubricating bearings and industrial-grade PLC, the mean time between failures (MTBF) of the machine exceeds 5000 hours.
