The Stainless Steel Liquid Pouch Filling Machine is an automatic form-fill-seal solution that integrates bag making, precise filling, and reliable sealing in one compact system. Designed for liquid, powder, and particle packaging, it supports composite packaging materials and uses PLC control to deliver stable operation, accurate positioning, and consistent bag quality. With flexible cutting and sealing options, the machine is well suited for high-efficiency strip-style back-seal pouch production in modern packaging lines.
Product Advantages
PLC-controlled stability and easy parameter management
The PLC control system provides wide parameter adjustability, smooth coordination of motions, and reliable long-term running performance, helping reduce downtime and improve batch-to-batch consistency.
Accurate photoelectric tracking
Equipped with a JULONG dual-color photoelectric eye, the machine maintains accurate film tracking and registration, improving sealing alignment and appearance when using printed films.
Reliable sealing for demanding products
The back sealing width is adjustable within 5–10mm (no pattern), while the horizontal sealing width is 8–10mm with optional diagonal mesh (1mm spacing) or straight pattern (2mm spacing). For liquid packaging, the leak-proof line design supports dependable sealing integrity.
Flexible cutting for different presentation needs
Choose flat cut or serrated cut using an independent cutter design, with 3mm spacing between cutters—ideal for producing neat strips, easy-tear edges, or retail-friendly finishes.
Efficient bag pulling and smooth film handling
A variable-frequency motor crank structure with heat-sealed bag pulling ensures stable traction, consistent bag length control, and smooth operation across different composite films.
Broad material compatibility and hygienic build
Constructed in stainless steel and designed for composite packaging materials (such as plastic laminates and foil-based structures), the machine supports hygienic production requirements and easy cleaning for daily operation.
Customizable size and packaging format
Machine size can be customized to match plant layout and process needs. Packaging type support includes liquid, powder, and particles, allowing one platform to serve multiple SKUs with appropriate dosing integration.
