SY-L180 / SY-L240 Single-Lane Liquid Packaging Machine (1ml–1000ml)
The ZSYAN SY-L180 and SY-L240 Single-Lane Liquid Packaging Machine is a high-precision vertical form-fill-seal system designed for fluid, sauce, and paste products from 1ml to 1000ml at speeds of 20 to 50 bags per minute. Equipped with a sanitary SUS316 pneumatic piston pump, leak-free anti-drip cut-off nozzles, and optional heated jacket agitation hoppers, it handles both free-flowing liquids (water, oils, vinegar, oral liquids) and viscous condiments (ketchup, chili sauce, honey, mayonnaise). Built with certified food-grade SUS304 stainless steel, photoelectric eye tracking (±1mm), and a 7-inch PLC touchscreen with 99 programmable recipes, it is an essential packaging workhorse for condiments, cosmetics, and agrochemicals.
Engineering Advantages & Technical Highlights
Precision-machined in Zhongshan, Guangdong with industrial-grade European standard electrical components.
Sanitary SUS316 Anti-Drip Piston Pump
Heavy-duty pneumatic piston dosing with positive suck-back cut-off nozzles guarantees zero dripping or liquid contamination on the sealing area.
Double-Jacket Heated Agitation Hopper (Optional)
Thermostatically controlled water-jacket heating (up to 95°C) and motorized scraper stirrers prevent oil separation and maintain smooth viscosity for pastes.
7-Inch Multi-Language PLC Control
Stores up to 99 SKU parameter sets. Real-time temperature control, automatic film shortage alarm, and automated fault diagnosis.

Material Suitability & Application Boundaries
Our engineering laboratory verifies physical handling tolerances to prevent jamming, breakage, or product degradation.
✅ Factory-Verified Ideal Applications
- Viscous Pastes & Sauces: Tomato ketchup, chili paste, salad dressing, honey, oyster sauce, peanut butter, chocolate syrup.
- Free-Flowing Liquids: Soy sauce, edible oil, cooking wine, mineral water, energy drinks, fruit syrup, vinegar.
- Personal Care & Chemicals: Shampoo, body wash, cosmetic lotions, alcohol sanitizers, liquid fertilizers, pesticide concentrates.
❌ Unsuitable Products & Alternative Systems
- Large Solid Particulates (>5mm): Sauces with whole nuts or beef chunks larger than 5mm (use our specialized rotor-pump or multihead weigher line).
- Dry Powders or Granules: Flour, salt, coffee granules (use our Powder Auger or Granule series).
Turnkey Packaging Line Integration Workflow
Seamlessly pair with upstream feeding and downstream end-of-line case packing equipment.
Product Hopper Infeed
Sanitary liquid/paste buffer hopper with auto-level float and optional electric heating.
Precision Piston Metering
Servo or pneumatic piston draws calibrated volume with zero bubble entrapment.
Vertical Former & Anti-Drip Fill
Film web folds around sanitary former tube while anti-drip nozzle dispenses inside.
Hermetic Heat Sealing
PID controlled sealing bars weld horizontal seam with leak-proof hermetic seal.
Chute Discharge
Finished liquid pouch slides down polished SUS304 discharge chute.
Frequently Asked Questions (FAQ)
Direct answers from our senior packaging machinery engineering team.
Q Can the machine handle hot-fill sauces (80°C – 90°C)?
Yes. The SY-L series features high-temperature food-grade silicone seals and Teflon-coated valves designed for continuous hot-filling up to 95°C.
Q How long does clean-in-place (CIP) changeover take?
The sanitary piston cylinder and valve disassembly utilizes tool-free tri-clamp sanitary couplings. Full washdown and changeover takes under 20 minutes.
