Fully-Automatic Net Bag Packaging Machine — 0.5–5kg Bags at Up to 40 per Minute, Zero Planned Stops

Stop bleeding margin to changeover downtime, hand-tie payroll, and bruised product. One machine puts your net-bag line back in profit.

Industry Pain Points

Be honest — how many of these hit your last shift?

• The 2 a.m. tube changeover. The net tube runs dry mid-harvest and the line stands still for 10–15 minutes while operators re-thread a new one. How many bags did that stop cost you this season?

• The hand-tie payroll. A semi-automatic clipper still needs an extra worker per shift feeding, tying, and trimming. When wages rise again, what happens to your margin per bag?

• The SKU standoff. Retail wants 1 kg lemons Monday, 2.5 kg potatoes Wednesday, 5 kg onions Friday. If every changeover eats an hour, which orders are you quietly declining?

• The rejected load. Inconsistent fills and sloppy ties trigger chargebacks at the distribution center. How much did your last claim cost — and wasn't a repeatably tied bag the cheaper option?

The Solution

The automatic net bag packing machine was engineered to delete exactly those four losses — not to add another pretty HMI to your floor.

Here is how to pack potatoes in mesh bags automatically, in one uninterrupted cycle: product enters via conveyor → the weigher drops the exact portion → the machine forms the bag from a continuous net tube → ties it with flat twine → inserts your printed label (optional) → discharges a retail-ready bag. 25–40 times per minute. One operator supervising.

The difference is in the dual-tube architecture: while one tube is running, your operator threads a fresh 200 m net roll onto the second. When the first runs out, the swap is instant — the line never stops. That single design decision moves all three OEE levers at once:

• Availability ↑ — tube-change stops eliminated, not shortened.

• Performance ↑ — a steady 25–40 bpm cadence, shift after shift.

• Quality ↑ — gear-and-proximity-switch positioning puts every tie and label in the same place, bag after bag.

Need a complete line? The unit docks cleanly with bucket conveyors, multihead weighers, and sorting trays to form a turnkey packing line.

Core Advantages

One Platform, Every SKU from 0.5 to 5 kg

1. Feature: Adjustable forming geometry covers 0.5–5 kg fills and 380/400 mm bag perimeters, with quick, tool-light changeover.
2. Advantage: Ask what net bag packing machine handles 0.5 to 5kg bags without swapping half its parts — this is the answer. A true 0.5-5kg small mesh bag packing machine that also carries a nonstop design is rare at any price.
3. Benefit: One capital purchase replaces several single-purpose machines, and you can say "yes" to short-run retail orders instead of declining them.

Nonstop Dual-Tube Production

1. Feature: Two net tubes work alternately; a fresh 200 m raschel net roll loads while the other runs.
2. Advantage: Tube changeover goes from a 15-minute line stop to a zero-second non-event.
3. Benefit: Every hour of your harvest window is monetized — more sellable bags per shift, no overtime to catch up.

A PLC Brain Your Operators Actually Understand

1. Feature: Schneider PLC, LS inverter, and Weintek color touch-screen HMI; standard data port for PC/MES connection; optional manual mode for training.
2. Advantage: A new operator is productive within a day, and production data flows to your office — not to a notebook that walks home.
3. Benefit: Lower labor cost per bag, fewer midnight troubleshooting calls, and the traceability retail contracts increasingly demand.

The Cheapest Bag in Produce, Retail-Ready

1. Feature: Consumables are only net bag + flat twine; the optional auto-labeler inserts your label during the tie.
2. Advantage: Mesh packaging runs cents below clamshells or printed film per bag — and ships to the shelf with your brand already in the customer's hand.
3. Benefit: At two million bags a season, even $0.02 saved per bag is $40,000 straight back to your bottom line.

Application Scenarios

Scene 1 — Potato & Onion Packing House. 3 a.m., harvest trucks queued outside. The line weighs, drops, ties, and discharges 5 kg onion bags in a continuous rhythm while one operator monitors the HMI. The second tube is already loaded; the line will not stop until the trucks are empty.

Scene 2 — Citrus Export Line. Export packers who have been vetting a citrus lemon net bag packaging machine manufacturer typically stop here for one reason: gentle handling, no sealed heat zone, and auto-inserted labels that make every 1–2 kg raschel bag shelf-ready for European retail.

Scene 3 — Hardware & Non-Food Co-Packing. Washers, bottle caps, fittings, promotional balls — anything solid that doesn't need a sealed bag. The same unit doubles as a hardware accessories net bag packing machine, switching from fruit to fasteners in minutes.

Also running daily on:

• Cabbage & brassicas — buyers comparing a cabbage mesh bag packing machine supplier shortlist choose this platform for bruise-free handling.

• Shellfish — draining, breathable mesh makes it a natural mussel oyster net bag packaging machine.

• Tomatoes, sweet potatoes, garlic, avocados and other solid produce.
