The ZONESUN liquid sachet packing machine is a dual-lane automatic packaging system designed for single-dose liquid and cream products from 1–12 ml, such as serums, facial creams, cleansers, hair oils, and travel-size cosmetics. It automatically completes feeding, dosing, pouch forming, filling, sealing, cutting, with optional coding and easy-tear functions. Using pneumatic ceramic piston pumps with anti-drip valves, it handles both medium- and high-viscosity products while preventing seal contamination. Product-contact parts are made of 316 stainless steel. A level sensor automatically signals the optional piston feeding pump for material replenishment, while the pressurized hopper ensures stable supply. Servo-driven film feeding delivers consistent sealing quality. Available in 2, 4, 6, 10, or 12-lane configurations, the machine supports four-side, three-side, or back sealing. Equipped with a Siemens PLC featuring recipe storage, self-diagnostics, and alarm functions, it achieves 60–100 sachets per minute and is suitable for cosmetic, pharmaceutical, food, and explosion-proof production environments.

Control Panel
The Siemens PLC system supports fault alerts, data storage, and self-diagnostic functions for intuitive and user-friendly operation.
Filling System
Pneumatic ceramic piston pumps enable precise filling from 1–12 ml, ideal for small-dose liquid products.
Lane Separation Assembly
Upper metal separators and lower guide plates prevent multi-lane film adhesion and deviation, ensuring neat sachet forming and uniform spacing across all lanes.
Pneumatic Cutting and Easy-tear Structure
Uses independently removable cutting blades and optional tear-notch design for convenient sachet opening.
Date Coder
Prints batch numbers or production dates directly during the packaging process.
Film Pulling System
A Siemens servo motor combined with photoelectric sensors tracks color marks accurately for uniform bag length and pattern alignment.
Pressurized Hopper with Feeding Pump
Works with an optional piston feeder and level sensor for automatic material replenishment.
