Are manual or semi-automatic liquid filling processes creating bottlenecks in your sauce, beverage, or edible oil packaging line? Do you need a hygienic, precise, and efficient way to portion liquids into individual sachets? The LD-320L Fully Automatic Liquid Filling & Sachet Packing Machine is a versatile form-fill-seal system engineered to streamline your packaging workflow. Constructed with food-grade SS304 stainless steel and featuring advanced servo-drive control, this machine automatically forms bags, fills them with a precise volume of liquid (from 5 ml to 300 ml), seals them, and cuts them off—all in one continuous operation. It is the ideal solution for producers of ketchup, soy sauce, vinegar, ice candy, and other free-flowing liquids requiring hygienic, portion-controlled packaging.

Why Choose the LD-320L Liquid Sachet Packing Machine? Solving Inefficiency, Waste & Hygiene Challenges

Achieve a seamless, high-speed packaging operation with intelligent features that directly address common production pain points.

• Eliminate Product Waste and Inconsistent Fill Volumes: Inaccurate fills lead to product give-away or customer complaints. This automatic liquid sachet machine utilizes a precision liquid metering pump and advanced stepping motor subdivision technology, guaranteeing a filling accuracy of ±1% . The system ensures each 5ml to 300ml sachet contains the exact amount, batch after batch.

• Ensure Food Safety and GMP Compliance: Contamination is a critical risk when handling edibles. The main frame and all parts contacting the product are constructed from hygienic SS304 stainless steel. The machine's design meets GMP standards, with smooth surfaces that are easy to clean. Key pneumatic components from Taiwan AirTac ensure reliable, contamination-free operation.

• Achieve High-Quality Seals for Leak-Free Sachets: Leaking sachets create mess and waste. The LD-320L features a unique embedded sealing system that creates firm, clear, and reliable seals suitable for a variety of heat-sealable lamination films (like BOPP, CPP/OPP, PET/PE). This ensures your liquid products—from thin vinegar to thicker ketchup—remain securely packaged.

• Streamline Production with Intelligent Controls and Coding: Manual adjustments slow down changeovers. The machine is equipped with a computer controller, advanced inverter, and an English touch screen interface. A high-sensitivity photoelectric eye ensures precise color tracing for accurate bag registration. The integrated ribbon code printer automatically prints up to 3 lines of information (batch number, expiry date) clearly and indelibly onto each sachet.

Key Features for High-Performance Liquid Packaging Lines

Engineered for precision, hygiene, and operational ease:

• Robust Stainless Steel Construction: Main frame and food contact parts made from SS304, ensuring durability and compliance with food industry standards.

• Precision Liquid Metering Pump: Single-head horizontal pneumatic pump with a metering range of 30-300ml and accuracy of ±1% . Filling volume and speed are adjustable.

• Intelligent Control System: Features PANASONIC PLC, step motor, frequency converter, and high-sensitivity photoelectric eye for precise bag formation and filling. Displays packaging rate and bag length settings.

• High-Quality Sealing Mechanism: Unique embedded sealing technology provides firm, clear, and leak-proof seals.

• Integrated Date Coding: Ribbon code printer (max 3 lines) for clear, indelible batch coding.

• Optional Heating & Stirring: An available heating and stirring device (SS304) ensures smooth filling of products that tend to separate or thicken.
