ZSYAN mesh bag bagging machines automate the entire onion packaging process from bulk intake to sealed mesh bag output at 20 to 35 bags per minute. The SY-WDJ2500A vertical model handles 200 to 1000g per bag, while the SY-WDJ5000A handles 200 to 5000g for larger export bags. Inclined configurations are available for delicate produce that cannot withstand vertical dropping. All machines feature servo-driven bag making, automatic buckling wire insertion, and missing-label or missing-wire alarms to prevent production errors.
Onion export is a high-volume, margin-sensitive business. Manual bagging requires 4 to 8 workers per shift, produces inconsistent bag weights, and creates bottlenecks during peak harvest seasons. An automated mesh bag bagging machine solves all three problems:
Speed: 20 to 35 bags per minute versus 8 to 15 bags per minute manually
Consistency: plus or minus 15mm bag length accuracy ensures every bag meets export quality standards
Labor reduction: one operator replaces 4 to 8 manual baggers
Error prevention: missing-mesh, missing-label, and missing-wire alarms catch defects before bags leave the line
For an exporter shipping 20 to 40 containers per month, automation is not a luxury. It is a competitive necessity.

The larger bucket and reinforced frame handle 5kg export bags commonly used for onion shipments to the Middle East and Europe.
For delicate produce such as tomatoes, berries, leafy greens, and soft onions, ZSYAN offers an inclined configuration that reduces drop height and prevents bruising. The slope angle is adjustable from 15 to 30 degrees depending on product fragility.
Automatic buckling wire insertion. Each mesh bag is sealed with a metal buckling wire that locks the bag opening. The machine feeds and crimps the wire automatically with a missing-wire alarm. Manual buckling is the number one cause of bag opening during transport. Automated crimping eliminates this failure mode.
Anti-snag surface treatment. All product-contact components have a smooth anti-snag finish that prevents mesh tears and product damage during high-speed operation. This is critical for preserving export-grade appearance.
Quick-swap mesh roll system. Change mesh rolls in under 5 minutes with electric-controlled net roller replacement and manual loading. No production interruption during roll changes.
Q1: What bag size is standard for onion export? The most common export bag sizes are 5kg and 10kg. ZSYAN machines can handle bags from 200g to 5000g depending on the model. The SY-WDJ5000A is specifically designed for 5kg and 10kg onion bags used in Middle East and European export markets.
Q2: Can the same machine package garlic and onion? Yes. The SY-WDJ series handles both onions and garlic interchangeably. Garlic bulbs are slightly smaller and lighter, so the machine may need minor sensor adjustments when switching products. The quick-swap mesh roll system also accommodates different mesh densities for onion versus garlic.
Q3: How many operators are needed to run a mesh bag bagging line? One operator is sufficient for the bagging machine itself. A second operator may be needed for mesh roll loading and finished bag stacking, depending on line configuration. This replaces 4 to 8 manual baggers.
Q4: What is the lead time for a mesh bag bagging machine? Standard vertical models ship within 15 to 25 working days. Inclined configurations with custom slope angles take 25 to 35 working days. Ocean freight to the Middle East takes 15 to 25 days. To Europe, 25 to 35 days.
Mesh bag packaging is suitable for:
Firm vegetables: onions, garlic, potatoes, sweet potatoes, citrus fruits
Processed foods: quail eggs, soy eggs, spiced snacks, ham sausages, jelly cups
Snacks and dry nuts: chestnuts, red dates, peanuts, passion fruits
Hardware and non-food items: nails, screws, small toys, craft supplies
Mesh bag packaging is NOT suitable for:
Soft juicy fruits that bruise easily (strawberries, ripe peaches)
Long thin or curved produce that tangles (long beans, snow peas)
Fragile mushrooms (button, oyster, enoki)
Very small loose particles (small cherries, peas)
