Automatic 50ml Liquid Sachet Filling & Pouch Packing Machine
This automatic liquid filling and sachet packing machine is designed for accurate, hygienic, and high-efficiency packaging of small-dose products from 1–50 ml. It integrates liquid quantitative filling (pump dosing), film forming, sealing, and finished-sachet output in one compact system. The equipment supports three-side or four-side sealing formats, making it ideal for single-serve packaging of sauces, beverages, edible oils, and a wide range of chemical liquids. With a stainless-steel control panel and stable servo-driven film pulling, the machine helps manufacturers upgrade from manual or semi-automatic packing to consistent, production-ready pouch packaging with reduced labor and minimized material waste.
Product Advantages
Wide product compatibility: Suitable for liquid products commonly packed in sachets, including soy sauce, vinegar, juice, milk, wine, cooking oil, beverage concentrates, and non-corrosive chemical liquids. The pump-based dosing method supports stable quantitative filling for small volumes, improving repeatability across batches.
Accurate quantitative pump filling: The liquid pump dosing system is optimized for 1–50 ml filling requirements. It supports consistent volume control and helps reduce overfill/underfill, improving product compliance and lowering giveaway costs.
High efficiency with simple operation: A PLC control system paired with a wide touch screen interface enables intuitive parameter setting, quick changeover, and smooth daily operation. The automation workflow reduces dependence on operator experience while maintaining stable output.
Servo film pulling for stable packaging: The servo-controlled film pulling system ensures steady bag length control and smoother running at higher speeds, supporting better registration and overall packaging quality compared with conventional pulling structures.
Reliable sealing and lower waste: The horizontal sealing system delivers consistent seal strength for common laminated films. Built-in alarm and protection logic helps detect abnormal conditions early, reducing downtime and preventing film and product waste.
Integrated process capability: The machine can complete feeding (with matched supply), measuring, filling, sealing, date/lot printing (optional), exhausting/charging (optional), counting, and finished product output, creating a streamlined sachet production line.
Durable, easy-to-clean construction: The stainless-steel panel design enhances durability and supports cleaning routines commonly required in food and daily chemical workshops.
Flexible pouch formats: Supports three-side sealing and can be configured for three-side or four-side seal styles according to packaging requirements, helping brands create professional single-dose packs suitable for retail, takeaway, and sample distribution.
