Engineering Model: SY-WDJ-DR / SY-TWJ2500/5000
SY-WDJ-DR / SY-TWJ Double-Roll Film Mesh Bag Packaging Machine
The ZSYAN SY-WDJ-DR (SY-TWJ) Double-Roll Film Mesh Bag Packaging Machine is a high-speed continuous packaging solution featuring a motorized dual-mandrel turret for non-stop roll changeovers. Packing produce from 500g to 5000g at speeds of 25 to 42 bags per minute, it eliminates 45 minutes of daily stoppage by pre-loading a standby tubular net roll that indexes into position in under 2 minutes. Combined with branded PE film banner heat-sealing and continuous coiled galvanized iron wire U-clipping (saving >45% consumable costs), it is engineered for high-throughput onion, potato, and citrus packhouses requiring non-stop 24/7 reliability.

Material Suitability & Application Boundaries
Our engineering laboratory verifies physical handling tolerances to prevent jamming, breakage, or product degradation.✅ Factory-Verified Ideal Applications
- Commercial Allium Packing: Yellow onions, red onions, garlic bulk net bags (1kg – 5kg).
- Root & Tuber Produce: Washed potatoes, sweet potatoes, beetroots, rutabagas.
- Citrus & Hard Fruit: Oranges, grapefruits, lemons, mandarins in breathable branded bags.
❌ Unsuitable Products & Alternative Systems
- Soft Delicate Fruits: Strawberries, ripe peaches (use shallow fruit punnets or flow wrap).
- Micro Granules Smaller than Mesh Aperture: Small cherry tomatoes or loose peas (use VFFS film pouches).
