Automatic Vertical Liquid Stick Sachet Packing Machine | Full Auto VFFS Liquid Filling & Sealing Equipment

This vertical liquid stick packing machine processes flexible packaging film rolls through a complete automated workflow without manual intervention:
Film unwinding & color mark photoelectric tracking for accurate bag positioning
316 stainless steel bag former shapes flat film into slim stick pouch structure
Peristaltic pump with variable-speed stirrer quantitatively feeds liquid materials; the hopper level sensor auto-triggers auxiliary feeding pump to avoid material shortage
Double-side back sealing with independent PID digital temperature control for leak-proof, neat diamond-shaped sealed edges
Integrated easy-tear device cuts uniform tear notches on each stick bag
Optional printer prints production batch numbers, production dates and shelf life
Cutting jaw separates finished stick packs, which can be conveyed via an optional finished product conveyor to inspection or secondary packaging stations

Wide Application Range
Applicable Liquid Materials
This machine accommodates thin to medium-viscosity liquid and semi-fluid products, including:
Food industry: honey, edible oil, tomato sauce, chili sauce, strawberry jam, seasoning sauce, fruit juice, yogurt, wine, jelly, edible vinegar
Daily cosmetics: shampoo, body cream, facial lotion, detergent liquid, essential oil, perfume liquid
Other liquid products: wasabi, alcohol oral liquid, nutrient syrups
Supported Packaging Styles
It produces slim back-sealed stick sachets with customizable shapes and auxiliary structures:
Standard straight stick bags, round-corner stick pouches, special-shaped fillet packs
Optional accessories to upgrade packaging: straight-line/U-type easy tear notches, linking bags, oval/butterfly/round punching hanging holes
Optional processing modules: ribbon printer, steel printer, thermal printer, gas filling device, squeeze exhaust, pinhole exhaust for airtight preservation

Standout Machine Features
1. Hygienic GMP Compliant Construction
The whole machine shell is made of full stainless steel, meeting global food and cosmetic production hygiene standards. The feeding hopper requires no heating, preventing liquid material deterioration or viscosity changes during continuous production. The long filling screw design keeps the sealing area clean, eliminating liquid overflow and weak sealing issues.
2. Ultra-Precision Intelligent Control
Independent digital PID temperature controllers support all composite packaging films, ensuring consistent sealing tightness without film melting or leakage
Photoelectric color mark tracking system delivers digital positioning, making sealing and cutting highly accurate with zero pattern deviation
Large color touch screen stores multiple production recipes; operators adjust speed, filling volume and bag length in one click
Servo motor + pneumatic integrated control improves machine stability, operation precision and intelligent automation level
3. Flexible & Customizable Production
Adjustable packaging speed and bag dimension range to match small-batch trial production and mass manufacturing
Modular optional components support personalized packaging demands: coding printers, various easy-tear structures, exhaust/gas filling units, hanging hole punching devices
Replaceable 316 bag formers and cutting jaws quickly switch between different stick bag sizes and shapes, shortening product changeover time
4. Stable & Low-Maintenance Operation
Variable-frequency AC driving motors reduce vibration during high-speed operation. The peristaltic pump feeding structure avoids direct metal contact with liquid materials, preventing cross-contamination and simplifying daily disassembly & cleaning. All electrical and mechanical parts adopt mature industrial-grade components for long service life.
