Mesh bag packing machines have become one of the most practical packaging solutions for fresh vegetables or fruit, industrial items, and retail-ready goods. Whether used for onions, potatoes, citrus, garlic, nuts, toys, or hardware pieces, these machines help factories maintain consistent packing quality while reducing labor costs.
This article helps you understand the machine’s structure, benefits, application range, and operation steps in a simple, practical way. If you are planning to automate your bagging process or simply want to learn more about the machine, this guide is for you.

A mesh bag packing machine, often called a net bag packing machine, is a packaging machine designed to accurately weigh/count, fill, and seal fresh produce or other products into net bags.
Unlike machines that use plastic film, this packing equipment specializes in using premade mesh netting or netting material from a roll. The final package is highly favored in the farm industry because the mesh allows for excellent ventilation. This key feature keeps products like potatoes, citrus, avocados, and onions fresh for longer by preventing moisture buildup and spoilage during storage and transport.
In short, this machine is the packing solution for replacing the traditional, slow, and error-prone hand-tying net bags.

The versatility of the net packing machine makes it indispensable across many kinds of industries. If your product needs airflow and transparency, this is the right machine for you:
Fresh Produce Packaging:
Root Vegetables: Potatoes, onions, garlic, carrots. (This is the most common application.)
Citrus Fruits: Oranges, lemons, mandarins, and grapefruit.
Hard Fruits: Apples, pears, avocados.
Non-Food Items Packaging:
Toys & Kids Items: Building Blocks, Mini Toys / Plastic Balls, Beach Toy Sets
Furniture & Decoration Accessories: Furniture Nuts, Decorative Pebbles, Ornaments
Many clients ask, "Can one machine pack different products?" The answer is yes. Landpack mesh packing machine are built with quick-change tooling and adjustable settings to accommodate a variety of produce (from small onions to large potatoes) simply by adjusting the bag size and weight target on the screen.

Switching from manual labour to an automatic packing system provides tangible benefits that directly impact your product quality.
1. Labour Reduction & Faster Output
Manual bag packing requires lots of workers to weigh, hold bags, fill, and tie them. With a net bag packing machine, one operator can oversee an output that normally requires several workers.
2. Accurate Weighing/Counting
The machine ensures consistent weights or counts, which is especially important when selling pre-weighed produce like 1kg, 2kg or 5kg fruit/vegetable packs, or pre-counted product like 2 pieces,4 pieces,6 pieces
3. Clean and Hygienic Packaging
Automation minimises human contact with the product, making the packing process more sanitary—an important factor for meeting food packaging standards
4. High Stability and Fewer Errors
Mesh bag packing machines are designed to handle different bag sizes and product types with stable performance. This reduces the risk of underfilled bags, overfilled bags, or inconsistent sealing.

Understanding the working principle of net packing machine helps you choose the correct specification. Below is the simplified working process:
1. Product Feeding
Products are fed into the machine by a z type product conveyor, hopper, or sorting machine.
2. Weighing or Counting
Depending on the product or packing requirements, the machine may use: Multihead weigher, Linear weigher, Vibrating Feeder to count or weigh accurately,
3. Bag Forming
Roll-film type: The machine forms a mesh tube from a roll and creates the bag on the spot.
4. Filling Process
After the net bag is prepared, the filling tube delivers the weighed product into the mesh bag. The machine controls speed and drop height to avoid damaging delicate items.
5. Sealing or Clipping
The mesh bag is then finished with: Metal clip sealing, Automatic tying, Label clipping (common in onion and citrus packing)
Many clients need to attach brand labels, weight measurements, etc., at this step, and we can also provide more customized services for you.
6. Output Conveying
The finished bag is moved onto a conveyor belt for manual collection or automatic carton loading/stacking.
A net bag packing machine relies on several core components that directly determine packing accuracy, efficiency, and long-term stability. Among these parts, the weighing system, sealing unit, and feeding structure are considered the most critical. Below is a simplified, importance-based layout of the main components.
| Priority | Component | Description |
|---|---|---|
| 1 | Weighing System | The core precision unit responsible for weight accuracy or product counting. Options include multihead weighers, linear weighers, or counting systems. |
| 2 | Sealing / Clipping Unit | Finalizes the packaging by clipping, heat sealing, or tying. Seal strength and stability directly impact transportation safety |
| 3 | Feeding System | Moves products from hoppers or elevators into the weighing unit. Stable feeding prevents blockages and ensures continuous production, especially for onions, citrus, garlic. |
| 4 | Bag Forming Tube | Creates mesh bags from roll film Its design determines bag size flexibility and smooth bag transfer. |
| 5 | Filling Chute | Ensure gentle and controlled filling to protect fragile produce and maintain the good shape of the packaging. |
| 6 | Labeling Device (Optional) | Attaches brand labels or tags during the sealing stage. Widely used for retail-ready produce in supermarkets. |
| 7 | Output Conveyor | Transfers finished bags to the next step for manual collection, carton packing, or palletizing. |
| 8 | PLC Control System | User interface for adjusting parameters, monitoring errors, and storing product recipes. |
