Automatic 50 ml Liquid Sachet Filling & Pouch Packing Machine
The Automatic 50 ml Liquid Sachet Filling & Pouch Packing Machine is a compact, fully integrated solution engineered for hygienic, accurate, and high-output packaging of small-dose liquids from 1–50 ml. Combining pump-based quantitative dosing, film forming, precise sealing, and finished-sachet discharge in one system, it helps manufacturers standardize single-serve packaging while reducing labor input and material loss. The machine supports both three-side and four-side sealing layouts, enabling professional retail-ready sachets for condiments, beverages, edible oils, and a wide selection of non-corrosive chemical liquids. With a stainless-steel operating panel and servo-driven film pulling, it delivers stable bag length control and consistent packaging quality, making it an ideal upgrade from manual or semi-automatic workflows to dependable production operation.
Product Features
Broad liquid compatibility for sachet packaging: Designed to handle common sachet liquids such as soy sauce, vinegar, juice, milk drinks, wine, cooking oils, beverage concentrates, syrups, and other non-corrosive chemical liquids. The pump dosing approach supports steady filling performance for small volumes, improving batch-to-batch consistency.
Precise pump dosing for 1–50 ml volumes: The quantitative liquid pump filling system is optimized for small-dose requirements, helping control fill accuracy and repeatability. By minimizing overfill and underfill, it supports compliance targets and reduces product giveaway costs.
PLC control with intuitive touch-screen operation: A PLC control system paired with a wide HMI touch screen enables fast parameter setting, straightforward operation, and efficient changeovers. The automation logic lowers dependence on operator experience while maintaining stable output quality.
Servo-controlled film pulling for stable running: The servo film pulling system improves bag length stability, enhances registration control, and supports smoother operation at higher running speeds compared with traditional mechanical pulling methods—resulting in better-looking sachets and fewer rejects.
Consistent sealing strength with waste-reduction safeguards: The horizontal sealing structure is designed to deliver reliable seal integrity on typical laminated packaging materials. Built-in alarm/protection functions help identify abnormal conditions early, reducing downtime and preventing unnecessary film and product waste.
Integrated process flow for streamlined production: The system can complete feeding (with matched supply), measuring, filling, sealing, optional date/lot printing, optional exhausting/charging functions, counting, and finished product output—creating a smooth sachet packaging workflow suitable for continuous production.
Durable stainless-steel structure for easy cleaning: The stainless-steel panel design supports workshop hygiene requirements and routine cleaning, improving durability and suitability for food and daily chemical production environments.
Flexible pouch formats for branding and channel needs: Supports three-side sealing and can be configured for three-side or four-side seal sachets based on packaging requirements, enabling professional single-dose packs for retail shelves, takeaway channels, sampling, and promotional distribution.
