In export markets and leading industries, packaging is more than just a protective layer for your products; it represents the identity and quality reputation of your brand. Even the slightest defect in print registration, design distortion, or variations in bag dimensions can damage brand identity and cause interruptions in automated packaging lines. Servotex technology is a transformative solution that has brought the control of printing lines and polymer bag processing to the highest engineering standards.
?What Is the Servotex System and How Does It Work
The Servotex system is one of the most precise Roll-to-Roll flexographic printing lines designed for polypropylene (PP) woven fabrics and polymer films. The term “Servo” in its name refers to the dedicated use of servo drive motors with real-time digital feedback.
Instead of relying on conventional mechanical gears, which can experience backlash, wear, and speed-related inaccuracies, Servotex servo motors continuously monitor and adjust roll tension and printing cylinder rotation every millisecond.
Key Benefits of Servotex Technology in Industrial Bag Manufacturing
1Millimeter-Level Precision and Register Accuracy
In industrial multi-color printing, even a few tenths of a millimeter of cylinder misalignment can blur text and distort logos. Servotex’s advanced system, combined with photocell sensors and stable tension control, ensures consistent register accuracy even at speeds exceeding 200 meters per minute. As a result, designs, barcodes, and technical text are printed with exceptional sharpness and readability.
2Preserving the Integrity and Uniformity of Polypropylene Fabric
Excessive or sudden tension can deform the warp and weft yarns of woven PP fabric and reduce the overall strength of the material. The servo tension-control system in Servotex guides the fabric smoothly without excessive stretching, preserving the original mechanical structure of the fibers.
3An Ideal Foundation for Heat Sealing and Airtight Packaging
Rolls that are printed and wound under stable web control can enter the converting and heat-sealing stage (such as with Convertex equipment) without wrinkles or edge misalignment. This uniformity allows laminated layers to bond together without air bubbles, ensuring that the final bag provides effective protection against moisture penetration and dust leakage.
Comparison of Servodrive (Servotex) Printing with Conventional Printing Systems
| Evaluation Criteria | Servotex System | Conventional Printing Machines |
|---|---|---|
| Color Register Accuracy | Precise digital control using servo drives | Potential for slippage and blurring in fine text |
| Roll Tension Control | Automatic control without deformation of PP fabric | Dependent on mechanical tension control, with potential for distortion |
| Image and Barcode Printing Quality | Highly sharp output with excellent barcode readability | Potential for ink spreading and scanner reading errors |
| Quality Consistency in High-Volume Production | Consistent from the first meter to the end of the roll | Possible quality fluctuations during continuous operation |
