SY-LNL400 / SY-LNL600 / SY-LNL800 Multi-Lane Liquid Sachet Packaging Machine
The ZSYAN SY-LNL Series Multi-Lane Liquid Packaging Machine is a high-speed multi-track form-fill-seal system supporting 4 to 20 parallel tracks, achieving throughput speeds from 80 to over 360 sachets per minute for liquid, syrup, paste, and gel stick packs from 1g to 50g. Featuring an advanced multi-channel servo rotary piston dosing valve, pneumatic zero-drip cut-off nozzles, and continuous rotary or intermittent longitudinal slitting, it delivers exceptional output density in a compact footprint. Certified food-grade SUS304/SUS316 stainless steel, dual-axis servo film pulling, and a 10-inch color touchscreen make it the standard for contract packers, condiment exporters, and pharmaceutical stick packaging plants.
Engineering Advantages & Technical Highlights
Precision-machined in Zhongshan, Guangdong with industrial-grade European standard electrical components.
High-Throughput Multi-Track Density
Produces hundreds of precision stickpacks per minute with continuous wide-web film slitting and multi-collar forming.
Servo Multi-Channel Piston Dosing
Individual micro-adjusters on each piston channel ensure volume deviation between all lanes is strictly kept under ±1%.
Versatile Precision Cutters
Supports flat cut, micro-zigzag easy-tear, round corner safety edge, and programmable chain sachet cuts.

Material Suitability & Application Boundaries
Our engineering laboratory verifies physical handling tolerances to prevent jamming, breakage, or product degradation.
✅ Factory-Verified Ideal Applications
- Single-Serve Food Condiments: Ketchup sticks, mustard pouches, honey tubes, energy gels, salad dressing, soy sauce.
- Nutraceuticals & Health Drinks: Collagen liquid drinks, liquid vitamins, herbal extracts, ginseng syrups, mouthwash.
- Hospitality & Amenities: Hotel shampoo packets, shower gel sticks, alcohol disinfectant wet-pack sachets.
❌ Unsuitable Products & Alternative Systems
- Large Pouches (>100ml): Use our Single-Lane (SY-L240) or Double-Lane (SY-L2L240) liquid baggers for large family pouches.
- Non-Fluid Solids: Use our Multi-Lane Granule or Powder machines.
Turnkey Packaging Line Integration Workflow
Seamlessly pair with upstream feeding and downstream end-of-line case packing equipment.
Master Roll Slitting
Wide-web film roll uncoils and passes rotary slitters, dividing into precision lane strips.
Multi-Former Tube Folding
Strips enter modular former array, shaping parallel tubular film lanes.
Servo Piston Injection
Multi-cylinder servo pump meters product down fill tubes with suck-back anti-drip.
Continuous Horizontal Sealing
Servo-driven heated sealer bars hermetically bond top and bottom borders.
Contour Cut & Lane Sorting
Rotary or guillotine cutter produces round-corner or zigzag stick packs onto discharge belts.
Frequently Asked Questions (FAQ)
Direct answers from our senior packaging machinery engineering team.
Q How consistent is fill weight across all lanes?
Our servo-driven multi-plunger pump provides lane-to-lane accuracy within ±0.5% with individual mechanical micrometer fine-tuning screws on each channel.
Q Can the machine produce round corners for cosmetic stick packs?
Yes. We offer pneumatic contour die cutters that produce smooth, premium round corners without sharp burrs.
