SY-UB200 Ultrasonic Semi-Automatic Mesh Bag Packaging Machine

The ZSYAN SY-UB200 Ultrasonic Semi-Automatic Mesh Bag Packaging Machine is an advanced, eco-friendly packaging solution that completely replaces traditional metal wire staples with precision high-frequency ultrasonic welding. Operating at 10 to 30 bags per minute, it eliminates metallic foreign object contamination and enables 100% downstream metal detector inspection—making it the gold standard for European and North American food export compliance. Featuring a smooth vertical anti-snagging mandrel chute and zero fastener consumables (saving ongoing wire/clip expenses), the SY-UB200 packages fresh citrus, garlic, individually wrapped snacks, nuts, and hardware items in lightweight, cost-effective tubular nylon and PE mesh netting.

Engineering Advantages & Technical Highlights

Precision-engineered in Zhongshan, Guangdong with industrial ultrasonic acoustic generators and food-grade SUS304 stainless steel.

⚡

100% Metal-Free Ultrasonic Sealing (Foreign Object Compliance)

Completely eliminates metal staples, clips, and wire rings. Finished packages can seamlessly pass through high-sensitivity food metal detectors and X-ray inspection lines without triggering false alarms, satisfying stringent overseas retailer audit directives.

🎯

Smooth Vertical Mandrel Infeed (Anti-Snagging Drop Chute)

Equipped with a precision mirror-polished vertical cylindrical chute. Material drops directly through the center without catching or tearing delicate tubular netting, preventing bag jamming and maximizing operator bagging cadence.

💰

Zero Fastener Consumables & Compact Portable Footprint

Requires zero aluminum clips or coiled iron wire—only the netting material itself. Built on a rigid SUS304 chassis weighing under 85kg with a compact footprint (~850 × 650 mm), making it effortless to integrate into existing packhouses.

✅ Factory-Verified Ideal Applications

Snack Foods & Confectionery: Mini sausages (火腿肠), fruit jellies (果冻), freeze-dried fruit (冻干水果), freeze-dried beef (冻干牛肉), biscuits, candies, and marinated quail eggs.
Nuts & Dried Fruit: Shelled peanuts, walnuts, almonds, chestnuts, hazelnuts, red dates, pecans, macadamias, and Brazil nuts.
Fresh Fruit & Citrus: Fresh lemons, limes, small oranges, passion fruits, and mandarins.
Firm Vegetables: Whole garlic bulbs, water chestnuts, shallots, and firm, drop-resistant produce.
Non-Food & Industrial: Plastic toys, ocean balls, colored decorative stones, hardware parts, and injection-molded components.

❌ Unsuitable Products & Alternative Systems

Soft Delicate Fruits: Ripe strawberries, soft persimmons, or ripe peaches (Recommended: SY-WDJ2500 Inclined Gentle Slider or Clamshell Punnet).

Turnkey Packaging Line Integration Workflow

Simple 5-step operational cycle delivers consistent, foreign-object-free mesh bag closures with minimal operator fatigue.

Step 01

Manual / Weighed Infeed

Operator feeds pre-weighed produce or snacks into the upper loading funnel.

Step 02

Vertical Anti-Snag Drop

Product glides smoothly through the polished mandrel into the pre-loaded tubular nylon netting.

Step 03

Pneumatic Ultrasonic Clamp

Foot switch or optical sensor triggers the pneumatic ultrasonic horn and anvil jaw assembly.

Step 04

High-Frequency Fusion & Cut

High-frequency vibrations (20kHz/35kHz) fuse the mesh fibers simultaneously into top and bottom seals while trimming the excess.

Step 05

Metal Detector Inspection

Finished mesh bag drops ready for inline metal detection and end-of-line carton packout.

Frequently Asked Questions (FAQ)

Direct technical answers from our industrial packaging machine engineering team.

Q Why should we choose ultrasonic sealing over conventional wire-clip baggers?

Strict food safety regulations in Europe, North America, and Japan increasingly penalize metal foreign body risks. Conventional metal clips prevent completed packages from passing downstream food metal detectors. Ultrasonic welding fuses nylon or PE mesh fibers cleanly without metal clips, enabling 100% online metal detection while eliminating ongoing staple/wire consumable expenses.

Q What types of netting materials work best with the SY-UB200?

The machine is optimized for tubular nylon mesh netting (which delivers superior tensile strength at low material cost) as well as thermoplastic polyethylene (PE) netting sleeves. Both seal cleanly within 0.4 to 0.8 seconds under ultrasonic acoustic vibration.
