Automatic Sachet Liquid Filling and Packaging Machine
This advanced automatic sachet liquid filling and packaging machine represents the pinnacle of precision and efficiency for the high-volume production of small-dose liquid products. Engineered to deliver unwavering reliability in continuous operation, this integrated system seamlessly combines film forming, quantitative pumping, accurate filling, hermetic sealing, date coding, and automatic counting into a single, streamlined process. It is expertly designed to handle sachets within the 1–50 ml range, offering versatile packaging formats including standard three-side or four-side seals, as well as customizable options for back-sealed or uniquely shaped sachets to fulfill specific branding and market demands. At its core, a sophisticated PLC control system paired with an intuitive touch-screen interface and a precision servo-driven film pulling mechanism ensures exceptional operational consistency. The result is a machine that guarantees uniform pouch appearance, exact dosing accuracy, and significantly minimized product waste, making it an indispensable asset for modern production lines in the food, daily chemical, and light pharmaceutical sectors.
Product Features
The machine is distinguished by a suite of robust features engineered for superior performance, operational ease, and long-term value.
Precision Dosing System: Utilizes a high-accuracy liquid pump for quantitative filling, ensuring stable and repeatable volume control for every sachet from 1ml to 50ml, which is critical for maintaining strict batch-to-batch consistency and product quality.
Versatile Sealing Configurations: Offers flexible packaging styles with support for both three-side and four-side seal formats. The system can be further customized to produce back-sealed sachets or special-shaped bags, providing ample creative freedom for distinctive product presentation.
Fully Integrated Automation: Automates the entire packaging workflow—from material feeding and precise measuring to filling, sealing, date printing, and final counting—within one continuous cycle. This integration dramatically enhances overall line efficiency and reduces manual intervention.
Intelligent Control & Operation: Features a reliable PLC controller coupled with a user-friendly touch-screen Human-Machine Interface (HMI). This allows for rapid parameter adjustments, easy recipe management, and simplified daily operation, reducing training time and operator error.
High-Stability Drive & Sealing: Incorporates a servo-driven film pulling system for precise web control, combined with a pneumatic horizontal sealing mechanism. This duo ensures smooth, stable running at high speeds, excellent sealing uniformity, and a superior, consistent packaging appearance.
Waste Minimization Protections: Equipped with comprehensive alarm and real-time monitoring functions. These systems promptly detect and alert operators to anomalies, helping to minimize both film material loss and product waste during unexpected stoppages or faults.
Hygienic & Durable Construction: Built with longevity and cleanliness in mind, the machine employs a stainless-steel panel design. This robust construction supports a long service life while facilitating easier and more thorough cleaning to meet hygiene standards in production environments.
Broad Material Compatibility: Designed to work efficiently with a wide range of common laminated packaging films, including structures like BOPP/PE, AL/PE, and Paper/PE. This flexibility allows producers to select materials based on specific barrier properties, shelf-life requirements, and cost considerations.
Customization Ready: Readily supports OEM customization to accommodate unique packaging needs. Options can include various bag-making styles such as pillow-type pouches, standing bevel bags, or other tailor-designed sachet shapes for market differentiation.
