SY-L2L180 Dual / SY-L2L240 Dual Double-Lane Liquid Packaging Machine
The ZSYAN SY-L2L180 Dual and SY-L2L240 Dual Double-Lane Liquid Packaging Machine is a dual-track vertical form-fill-seal solution engineered to double output capacity up to 40 to 100 bags per minute for liquid and paste sachets from 1ml to 1000ml per lane. By housing twin synchronized filling and sealing assemblies within a single rigid stainless chassis (footprint only 1750 × 1300 × 1700 mm), it provides 2x the throughput of single-lane baggers while reducing required workshop footprint and operator staffing by over 40%. Featuring twin independent SUS316 sanitary piston pumps, dual-track photo-eye tracking, food-grade SUS304 stainless steel frame, and an intuitive 7-inch PLC interface, it represents the ideal high-ROI expansion for sauce, oil, and liquid condiment packers.
Engineering Advantages & Technical Highlights
Precision-machined in Zhongshan, Guangdong with industrial-grade European standard electrical components.
Dual-Track Synchronized Capacity (2x)
Twin independent filling tracks run in unison on one chassis, doubling sachet throughput without requiring additional electrical lines or floor space.
Independent Lane Volume Calibration
Each track is driven by its own precision micrometer piston pump, allowing individual fine-tuning of dosing weight down to ±0.5%.
Compact Workshop Architecture
Single integrated infeed hopper feeds both tracks simultaneously, simplifying piping and Clean-In-Place (CIP) sanitation protocols.
Technical Specifications Matrix (EAV Model)

Material Suitability & Application Boundaries
Our engineering laboratory verifies physical handling tolerances to prevent jamming, breakage, or product degradation.
✅ Factory-Verified Ideal Applications
- Condiments & Sauces: Ketchup sachets, mayonnaise packs, soy sauce packets, chili sauce, mustard.
- Beverage & Edible Oils: Olive oil pouches, cooking oil, fruit puree, liquid honey, energy syrups.
- Household & Hospitality: Hotel amenity shampoo, shower gel, liquid detergent, hand sanitizer gel.
❌ Unsuitable Products & Alternative Systems
- High-Speed Micro-Sticks (<15g, >150 bags/min): For large-scale retail stick packs, our 4 to 20 lane Multi-Lane SY-LNL series is more economical.
- Dry Powder or Granular Products: Use our Double-Lane Granule (SY-G2L Dual) or Powder (SY-P2L Dual) machines.
Turnkey Packaging Line Integration Workflow
Seamlessly pair with upstream feeding and downstream end-of-line case packing equipment.
Central Hopper Infeed
Split-manifold sanitary hopper dispenses equal product volume to twin cylinders.
Dual-Stroke Piston Metering
Twin synchronized pistons draw calibrated volume with dual check valves.
Dual Film Web Forming
Twin forming collars fold parallel film webs with individual eye mark correction.
Synchronized Cross-Sealing
Heated jaws seal and cut both bags simultaneously with clean tear notches.
Twin Track Discharge
Dual output ramps deliver separated finished pouches to downstream conveyor.
Frequently Asked Questions (FAQ)
Direct answers from our senior packaging machinery engineering team.
Q Can one lane operate if the other is temporarily paused?
Yes. Each track features independent pneumatic control and temperature zones, allowing single-lane test runs or dual-lane high output.
Q Is the double-lane machine harder to clean than a single-lane?
No. The two pump blocks share a unified manifold that connects directly to your central CIP wash loop with tool-free tri-clamp fittings.
