Designed for manufacturers who demand consistent dose accuracy and a premium sachet appearance, this automatic liquid sachet filling and packaging machine delivers reliable, high-speed production for small-volume packs from 1–50 ml. The system combines film forming, quantitative pump dosing, filling, sealing, date printing, and counting into one compact, integrated unit—reducing manual handling, simplifying line layout, and improving overall equipment efficiency. Built around stable PLC control, an intuitive touch-screen HMI, and a servo-driven film pulling mechanism, the machine helps maintain repeatable pouch length, neat seal lines, and clean cut edges throughout continuous operation. It supports mainstream three-side and four-side seal structures, and can be configured for back-sealed or special-shaped sachets to meet branding, channel, and marketing requirements. With a hygienic stainless-steel-oriented design and practical alarm/monitoring functions, it minimizes downtime and material loss while supporting routine cleaning and long-term production stability for food, daily chemical, and light pharmaceutical liquid applications.
Product Features
- High-precision quantitative pump filling: A dedicated liquid pump dosing system supports stable volume control across 1–50 ml, helping reduce overfill, improve batch uniformity, and protect product cost.
- Flexible sachet formats: Standard support for three-side seal and four-side seal; optional configurations enable back seal and special-shaped sachet designs for differentiated shelf impact.
- All-in-one automated workflow: Film unwinding and forming, dosing, filling, sealing, date coding, and counting are completed in one continuous cycle, reducing labor and improving throughput.
- PLC control with touch-screen HMI: Clear parameter setup and recipe management enable fast changeovers, simplified operation, and easier training for production staff.
- Servo film pulling for consistent pouch length: Servo-driven film transport improves running stability and repeatability, supporting clean registration and a uniform finished-pack appearance.
- Pneumatic horizontal sealing for uniform seal quality: Stable sealing pressure and repeatable jaw motion help produce smooth seal lines and reduce the risk of leakage in liquid applications.
- Waste-reduction monitoring and protection: Alarm and status monitoring functions help detect abnormalities early, minimizing film loss, product waste, and unplanned stops.
- Durable, hygienic construction: Stainless-steel panel structure supports long service life and convenient routine cleaning, suitable for everyday production environments with hygienic requirements.
- Wide compatibility with common laminates: Works with mainstream roll-film structures such as BOPP/PE, AL/PE, and Paper/PE, allowing barrier performance and packaging cost to be balanced by application.
- OEM-ready customization options: Optional bag-making styles (e.g., pillow-type, standing bevel, and tailored designs) enable packaging differentiation to match brand positioning and market needs.
