Explore Our MachinesAdvanced Four-Side Sealing Technology
Precision engineering meets high-speed automation to deliver perfectly sealed, airtight sachets for premium product protection.
Four-side sealing packaging is the gold standard for single-serve sachets in industries where hygiene, shelf life, and portion control are critical. Unlike standard three-side seal pouches or stick packs, the four-side seal configuration offers a highly symmetrical, uniform aesthetic and superior structural integrity. This prevents leakage and maintains an absolute barrier against moisture, oxygen, and light.
Our smart packaging lines utilize advanced PLC control systems (Siemens/Omron) integrated with high-precision servo motors to regulate film pulling and sealing pressure. This ensures that every sachet is sealed with consistent thermal energy, minimizing material waste and maximizing operational efficiency.
- Multi-Lane Scalability: Expand production from 2 to 12+ lanes to achieve output speeds of up to 400 sachets per minute.
- Flexible Dosing Systems: Compatible with rotary valves, auger fillers, liquid piston pumps, and volumetric cups.
- Hermetic Seal Integrity: Advanced PID temperature control ensures zero-leakage sealing across various laminated films.
- Smart Diagnostics: Real-time error detection, film-end sensors, and automatic rejection systems for quality control.
