Fresh Produce Packaging Is Changing: Why Net Bag Automation Matters

Industry Trends, Packaging Challenges and Automated Solutions for Fruits, Vegetables and Root Crops

Fresh produce is a high-volume business, but packing it efficiently is not always as simple as it looks.

Potatoes, onions, garlic, oranges, lemons and other fresh produce vary in size, shape and weight. At the same time, retailers and distributors increasingly expect consistent pack weights, stable production and reliable presentation.

As production grows, these requirements put more pressure on the packing process.

According to the Food and Agriculture Organization of the United Nations (FAO), global fruit and vegetable production reached approximately 2.1 billion tonnes in 2023.

At the same time, fruits and vegetables have a particularly high level of food loss. FAO estimates that 25.4% of fruits and vegetables were lost between harvest and retail in 2023, compared with 13.3% for food overall.

This does not mean packaging is responsible for these losses. Food can be lost during harvesting, handling, storage, transportation and other stages.

But it does highlight an important point:

The more efficiently fresh produce is handled throughout the supply chain, the more important each individual process becomes.

And packaging is one of those processes.

The Fresh Produce Industry Is Getting Bigger — So Is the Packaging Challenge

Fresh produce is different from many other packaged products.

A bag of chips contains relatively uniform pieces. A bag of potatoes or oranges can contain products with very different weights and dimensions.

For example, one potato might weigh 120 g while another weighs 250 g.

The same applies to onions, citrus fruits and other agricultural products.

Yet the finished package may still need to meet a specific target:

500 g · 1 kg · 2 kg · 2.5 kg · 5 kg

This creates a basic challenge for packers:

How do you consistently reach the target weight when the individual products are not uniform?

For small production volumes, manual weighing may be enough.

For larger production volumes, however, the process becomes much harder to control.

Where Manual Net Bag Packing Starts to Become a Bottleneck

A traditional packing process may look something like this:

Weigh → Adjust → Fill Bag → Close Bag → Check → Repeat

It sounds simple.

But when the same process has to be repeated hundreds or thousands of times a day, small inefficiencies start to add up.

Inconsistent Pack Weights

Suppose the target is 1 kg per bag.

An operator may deliberately add a little extra product to avoid underweight packages.

One extra onion may not seem important.

But if thousands of bags are produced every day, that extra product becomes a real material cost.

High Labor Requirements

Manual weighing and filling are repetitive tasks.

As production increases, more operators may be needed simply to maintain output.

Uneven Production Speed

Human-operated processes naturally fluctuate.

The production line may run quickly during one period and slow down during another.

More Manual Handling

Every additional handling step creates another opportunity for products to be dropped, squeezed or damaged.

For fresh produce, careful handling matters.

The Problem Isn't Just Labor. It's Consistency.

This is an important distinction.

When manufacturers consider automation, the first question is often:

How many workers can the machine replace?

But there is another question that may be even more important:

How consistent can the production process become?

An automated packing system can help standardize several steps:

Target weight

Product feeding

Bag filling

Bag closing

Production flow

Finished product output

The goal isn't simply to remove manual work.

The goal is to make the same process happen more consistently, bag after bag.

Why Net Bags Are Still Used for Fresh Produce

Net bags remain a practical packaging format for many types of fresh produce.

They allow the product to remain visible while providing ventilation and a relatively simple way to group products for retail or distribution.

Common applications include:

Potatoes

Onions

Garlic

Oranges

Lemons

Limes

Carrots

Ginger

Walnuts

Other solid agricultural products

But there is an interesting contradiction.

The package itself may be simple. The process of producing thousands of consistent packages is not.

The system needs to coordinate:

Product feeding → Accurate weighing → Bag filling → Closing → Product output

That is where automation becomes valuable.

What Can Automation Actually Solve?

A net bag packaging machine does not solve every problem in fresh produce processing.

But it can address several important issues around the packing stage.

01 — Automatic Weighing

Instead of relying on an operator to repeatedly weigh and adjust products, an automated weighing system can calculate the required product quantity according to the target weight.

02 — Continuous Product Feeding

Products can be continuously supplied to the weighing system, reducing repetitive manual feeding.

03 — Automatic Bag Filling

Once the target weight is ready, the product can be transferred into the net bag automatically.

04 — Automatic Clipping

The filled bag can then be closed automatically, creating a more consistent finished package.

05 — Reduced Repetitive Labor

Operators can focus more on monitoring and managing the production line instead of manually weighing and filling every bag.

This is where automation starts to create value beyond simple speed.

How an Automatic Net Bag Packaging Line Works

A typical automated process can be organized into several steps:

Feeding : Fresh produce is continuously delivered to the weighing system.
↓
Automatic Weighing: The weighing system selects the appropriate product quantity to reach the target weight.
↓
Net Bag Filling: The weighed product is transferred into the net bag.
↓
Clipping / Closing:  The filled bag is automatically closed.
↓
Labeling: Depending on the configuration, labeling can be integrated into the line.
↓
Finished Product

Each stage has a specific role.

Output

The finished bags are discharged for collection, secondary packing or palletizing.

Instead of treating weighing, filling and closing as separate manual operations, the entire process becomes one continuous workflow.

What Happens When Production Starts to Scale?

This is where automation becomes particularly relevant.

A manual packing process may work perfectly well when production is relatively small.

But imagine the production volume doubles.

The business now needs:

2× the product

2× the bags

2× the weighing

2× the filling

Does that mean the factory also needs twice as many people?

Not necessarily.

This is one of the main reasons manufacturers move toward automated packaging.

Automation allows production capacity to increase without simply adding the same amount of repetitive manual work.

The question changes from:

“How many people do we need to pack these bags?”

to:

“What level of automation do we need to achieve our target output?”

That is a much more scalable way to look at packaging.

Semi-Automatic or Fully Automatic?

Not every business needs a completely automated production line.

The right solution depends on production volume, labor availability, target output and budget.

Semi-Automatic Net Bag Packaging

A semi-automatic system can be suitable when production volumes are moderate.

The operator may still be involved in certain steps, while the machine handles key processes such as weighing, filling or clipping.

This can be a practical way to reduce repetitive work without completely changing the existing workflow.

Fully Automatic Net Bag Packaging

For higher-volume production, the complete process can be integrated:

Feeding → Weighing → Filling → Clipping → Output

This reduces manual intervention and allows the line to operate continuously.

There is no universal answer.

The right automation level is the one that matches the actual production requirement.

What Should You Consider Before Choosing a Net Bag Packaging Machine?

Choosing a machine based only on advertised speed can be risky.

The machine needs to match the product.

Product

What are you packing?

Potatoes, onions, garlic and citrus may require different handling configurations.

Target Weight

Are you packing 500 g, 1 kg, 2 kg or 5 kg bags?

Product Size

Are the products relatively uniform, or do their sizes vary significantly?

Bag Specification

What is the bag size and net structure?

Production Capacity

How many bags per minute do you actually need?

Automation Level

Do you need semi-automatic packing or a complete automatic line?

Future Capacity

Will your production volume remain the same, or are you planning to scale?

That last question is easy to overlook.

A machine that works today should ideally not become the bottleneck six months later.

How TOUPACK Approaches Net Bag Packaging

This is where the industry problem connects naturally with the machine.

TOUPACK provides net bag packaging solutions for fruits, vegetables and agricultural products, including applications such as potatoes, onions, garlic and citrus fruits.

The system can combine automatic weighing, net bag filling and clipping into a continuous packaging process.

For one current fully automatic configuration, TOUPACK lists a 0.5–5 kg packing range and a production speed of 25–40 bags per minute, depending on the actual product and configuration.

The important point is not simply the speed.

It is the integration.

Instead of:

Manual Weighing → Manual Filling → Manual Closing

the production process becomes:

Automatic Weighing → Automatic Filling → Automatic Closing → Finished Bag

This can help manufacturers improve consistency while reducing repetitive manual operations.

The exact configuration can then be adjusted according to the product, target weight, bag specification and required output.

And that is probably the most important point when choosing packaging equipment:

The packaging line should fit the product — not the other way around.

When Does Net Bag Automation Make Sense?

There is no single production volume at which every company must automate.

But there are some clear signs.

You may want to consider automation when:

Manual weighing is slowing production.

Operators spend too much time filling bags.

Pack weights are inconsistent.

Labor requirements continue to increase.

Production needs to run for longer periods.

You need a more consistent finished package.

You are planning to significantly increase output.

In other words, automation becomes interesting when manual work starts limiting production rather than supporting it.

The Goal Is Not Just Faster Packaging

For fresh produce companies, packaging automation is ultimately about more than speed.

It is about building a process that can handle growing production without adding the same amount of repetitive work.

A well-designed net bag packaging system can bring together:

Accurate Weighing
Stable Feeding
Automatic Filling
Consistent Closing
Continuous Production

For some businesses, that may mean lower labor pressure.

For others, it may mean more consistent weights.

For growing producers, it may simply mean being able to handle more orders with the same production space.

The right answer depends on the operation.

And that is exactly why packaging equipment should be designed around the product, rather than selected from a machine specification sheet alone.
