Automatic Sachet Liquid Filling and Packaging Machine
This automatic sachet liquid filling and packaging machine represents a pinnacle of precision engineering for the high-speed, small-dose packaging market. Designed specifically for the efficient production of 1–50 ml liquid sachets, it integrates the entire packaging process—from film forming and precise quantitative pumping to filling, sealing, date printing, and final counting—into one seamless, compact system. Engineered for unwavering stability in demanding continuous production environments, the machine offers flexible configuration, supporting standard three-side or four-side seal formats, as well as customizable options like back-sealed or uniquely shaped sachets to perfectly align with specific branding and market strategies. At its core, a reliable PLC control system paired with an intuitive touch-screen interface and a precision servo-driven film pulling mechanism ensures consistent pouch quality, exceptional dosing accuracy, and minimal product waste, making it an indispensable asset for industries ranging from food and daily chemicals to light pharmaceuticals.
Product Features
The machine’s design philosophy centers on reliability, flexibility, and user-centric operation, delivering distinct advantages across every stage of the packaging workflow.
Precision Dosing and Consistency: Utilizing an advanced liquid-pump dosing system, the machine guarantees stable and accurate volume control for sachets from 1 to 50 ml, ensuring remarkable batch-to-batch consistency critical for product quality and customer trust.
Versatile Sealing and Bag-Making: It provides exceptional format flexibility, natively supporting both three-side and four-side seal sachets. Furthermore, it can be readily customized to produce back-seal pouches or a variety of special-shaped bag styles, offering brands a powerful tool for packaging differentiation.
Fully Integrated Automation: The system orchestrates a complete, continuous workflow—automating material feeding, precise measuring, sterile filling, hermetic sealing, clear date coding, and accurate counting—thereby significantly boosting overall production line efficiency and reducing manual intervention.
Intelligent Control and Operation: Governed by a robust PLC and featuring a user-friendly touch-screen Human-Machine Interface (HMI), the machine allows for rapid parameter adjustments, easy recipe management, and simplified daily operation, minimizing setup time and operator training requirements.
High-Speed Stability and Quality: The combination of a servo-driven film pulling system and a pneumatic horizontal sealing unit ensures smooth, stable operation at high production speeds. This synergy results in superior sealing uniformity and a consistently professional packaging appearance for every sachet.
Waste Minimization Systems: Integrated alarm and real-time monitoring functions proactively detect and alert operators to abnormal conditions, effectively helping to minimize both packaging film loss and valuable product waste during production.
Hygienic and Durable Construction: Built with longevity and cleanliness in mind, the machine features a stainless-steel panel design. This not only ensures a long service life in industrial environments but also facilitates easier and more thorough cleaning to meet hygiene standards.
Broad Material Compatibility: Designed to work efficiently with common laminated film structures such as BOPP/PE, AL/PE, and Paper/PE, the machine offers producers the flexibility to choose materials based on specific barrier protection needs and cost considerations.
Customization Capability: Ready for OEM requirements, the machine supports optional bag-making styles including pillow-type, standing bevel, and fully tailored designs, providing a solid foundation for meeting unique and differentiated packaging demands.
