Product Introduction
The Stainless Steel Liquid Pouch Filling Machine is a compact automatic form-fill-seal (FFS) system engineered to integrate pouch forming, accurate dosing, and stable sealing in one continuous workflow. Built for strip-style back-seal sachets, it runs smoothly on composite packaging films and supports liquids as well as powders and granules when paired with the appropriate feeding and dosing unit. With PLC-based control, dependable film tracking, and flexible sealing/cutting configurations, this machine helps manufacturers standardize pouch appearance, reduce operator intervention, and maintain consistent output in modern high-efficiency packaging lines. Its stainless-steel construction supports hygienic production environments and simplifies routine cleaning, making it a practical choice for daily operation where both performance and sanitation matter.
Product Features
Integrated form-fill-seal workflow
Combines bag making, filling, and sealing into a single automated process, minimizing manual handling and improving overall line efficiency for strip-style sachet production.
PLC control for stable operation and repeatable results
A PLC control system enables reliable motion coordination and broad parameter adjustment, helping maintain stable long-term running performance, faster changeovers, and consistent pouch quality across batches.
Precise photoelectric registration for printed films
Equipped with a JULONG dual-color photoelectric eye to track film marks accurately, supporting neat registration and improved sealing alignment when using printed composite films.
Leak-resistant sealing design for liquid products
Back sealing width is adjustable from 5–10mm (plain seal), while horizontal sealing width is 8–10mm with optional diagonal mesh (1mm spacing) or straight pattern (2mm spacing). The sealing structure is designed to support strong integrity and reduce leakage risk during liquid packaging.
Flexible cutting options for different market presentations
Supports flat cutting and serrated cutting via an independent cutter structure. With 3mm spacing between cutters, it helps produce clean strip separation, easy-tear edges, and retail-ready finishes.
Stable bag pulling and smooth film handling
A variable-frequency motor crank mechanism combined with heat-sealed bag pulling improves traction stability, supports accurate bag-length control, and promotes smooth running on various composite film structures.
Hygienic stainless-steel build and broad film compatibility
Stainless-steel construction supports cleaning convenience and hygienic requirements. Designed for composite packaging materials, including common laminated plastic films and foil-based structures used in food, daily chemical, and industrial packaging.
Customizable configuration for plant layout and SKU needs
Machine dimensions can be customized to match factory space and line integration requirements. The platform supports liquid, powder, and particle applications, enabling one machine concept to serve multiple products with suitable dosing solutions.
