SY-WDJ2500 / SY-WDJ5000 Inclined Automatic Mesh Bag Packaging Machine
The ZSYAN SY-WDJ2500 and SY-WDJ5000 Inclined Automatic Mesh Bag Packaging Machine is an industrial produce and snack bagging system engineered for gentle, high-speed mesh packaging from 200g to 5000g at speeds up to 40 bags per minute. Its 45° inclined feeding chute minimizes drop impact for yellow onions, potatoes, citrus, garlic bulbs, and multipack snack pouches. The machine utilizes continuous coiled galvanized iron wire to form secure U-shaped metal closures online, delivering 5,000 to 8,000 closures per spool while reducing clipping consumable costs by over 45% compared to pre-made aluminum clips. Built with food-grade SUS304 stainless steel contact surfaces, a dual servo drive (±1mm bag length accuracy), and a 7-inch PLC touchscreen storing 99 recipes, it operates on single-phase AC220V power.
Engineering Advantages & Technical Highlights
Precision-machined in Zhongshan, Guangdong with industrial-grade European standard electrical components.
Continuous Coiled Wire U-Clipping
Online cold-draw wire feed forms high-strength U-clips automatically. Delivers 5,000-8,000 bags per spool, eliminating frequent downtime and cutting clip costs by 45% compared to aluminum clips.
45° Anti-Impact Chute Geometry
Gentle sliding descent prevents produce bruising, skin cracking, and potato chipping. Ideal for premium grade apples, citrus, persimmons, and delicate bagged snacks.
Synchronized Thermal Wine-Glass Labeling
Applies wine-glass tags or flat carry-handle ribbons simultaneously during the clipping cycle. Supports real-time thermal barcode, date code, and weight printing.

Material Suitability & Application Boundaries
Our engineering laboratory verifies physical handling tolerances to prevent jamming, breakage, or product degradation.
✅ Factory-Verified Ideal Applications
- Root & Bulb Vegetables: Yellow/red onions, washed potatoes, garlic bulbs, ginger roots, shallots, sweet potatoes.
- Citrus & Hard Fruits: Oranges, lemons, limes, mandarins, grapefruits, firm apples, avocados, passion fruits.
- Hard-Shell Seafood: Live or frozen clams, blue mussels, sea scallops, cockles, oysters.
- In-Shell Nuts & Multipacks: Chestnuts, walnuts, peanuts, and secondary multipack bundling of small snack bags.
❌ Unsuitable Products & Alternative Systems
- Leafy Greens: Lettuce, spinach, Chinese cabbage (mesh strands and wire crimp tear soft leaves; use horizontal flow wrap).
- Soft Berries & Stone Fruits: Strawberries, ripe peaches, raspberries (fragile skin bruises easily; require rigid clamshell trays).
- Long Entangling Vegetables: Green beans, scallions, asparagus (tend to bridge and tangle across the chute).
- Sub-Aperture Granules: Cherry tomatoes under 15mm, loose peas, berries (fall through mesh netting apertures).

Frequently Asked Questions (FAQ)
Direct answers from our senior packaging machinery engineering team.
Q How does continuous coiled wire save 45% compared to pre-made clips?
Pre-made aluminum clips are sold in short plastic sticks at a high manufacturing markup and require frequent manual reloading every 400-600 bags. ZSYAN’s continuous galvanized wire comes on large 15kg spools that yield 5,000 to 8,000 clips per spool. The machine draws, cuts, and bends the wire online, reducing consumable cost by 45% and eliminating frequent operator stops.
Q Can the machine be integrated with an existing multihead weigher?
Yes. ZSYAN mesh baggers feature standard dry-contact handshake signals (Ready, Discharge, Fault) compatible with all major multihead weigher brands (Ishida, Yamato, Bilwinco, and ZSYAN combinations). We provide CAD platform integration drawings within 12 hours.
Q What is the warranty and spare parts availability?
We provide a 12-month complete mechanical warranty. Wear components such as wire-forming dies, cut-off blades, and guide bushings are kept in stock for 24-hour dispatch via DHL/FedEx worldwide.
