Can Your Factory Handle 24/7 Production? 7 Packaging Weak Points to Check First

Running a food packaging machine for several hours is one thing.

Running a packaging line continuously across multiple shifts is something completely different.

When a food factory starts moving toward 24/7 production, the question should not simply be:

“Can this machine reach the required speed?”

A better question is:

“Can the entire packaging system maintain stable production for long hours without frequent stops, manual adjustments or quality problems?”

A packaging machine may have enough theoretical capacity, but a small weakness in filling, film feeding, sealing, coding, product feeding or conveying can eventually become a serious production bottleneck.

For food manufacturers preparing for higher production volumes, here are seven packaging weak points worth checking before moving toward continuous production.

1. Filling Accuracy: Can You Maintain the Target Weight?

Filling accuracy is one of the first things to examine.

A machine may run quickly, but if the actual filling weight fluctuates too much, the factory can face several problems:

• product giveaway

• underweight packs

• customer complaints

• unstable production records

• additional manual checking

• frequent machine adjustments

The problem becomes more noticeable when a factory operates for multiple shifts.

A small weight deviation that occurs occasionally may be manageable.

The same deviation repeated thousands of times per day can become expensive.

What should you check?

Look at the relationship between:

Product characteristics → dosing method → target weight → filling accuracy → production speed

Different products require different dosing systems.

Free-flowing products such as grains, rice, beans and some snacks may be suitable for multihead weighing.

Powders may require an auger or other powder dosing system.

Liquids, pastes and sticky products require completely different filling solutions.

Therefore, increasing speed should never be separated from filling accuracy.

A high-speed machine that cannot maintain stable dosing is not really a high-productivity solution.

2. Film Feeding: Can the Packaging Material Run Continuously?

Film feeding is another common source of unexpected downtime.

When a VFFS machine runs continuously, the packaging film needs to move through the machine smoothly and consistently.

Problems may occur because of:

• film misalignment

• unstable film tension

• poor film quality

• incorrect film dimensions

• film tracking problems

• film roll changes

• printing or registration issues

A machine can be mechanically capable of running for long hours, but the packaging material itself may become the limiting factor.

This is particularly important when factories use printed film.

The machine needs to detect the registration mark accurately and maintain the correct position of the printed design throughout production.

A useful question for your packaging supplier

Don't only ask:

“What is the maximum packaging speed?”

Also ask:

“What film specifications are required to achieve stable operation at that speed?”

The answer can have a major impact on actual production performance.

3. Sealing: Will the Bags Still Look Good After Hours of Production?

Sealing is often underestimated.

At the beginning of a production run, the bags may look perfect.

After several hours, however, changes in temperature, film characteristics, product dust or machine adjustments can affect sealing performance.

Typical problems include:

• weak seals

• wrinkled seals

• product trapped in the sealing area

• uneven sealing

• excessive sealing temperature

• film sticking to the sealing jaws

For food packaging, the seal is not simply an aesthetic feature.

It protects the product and affects shelf life, transportation and customer perception.

A packaging line designed for long production hours therefore needs stable temperature control and appropriate sealing parameters.

The machine should also be designed around the actual film structure being used.

A packaging machine cannot compensate for unsuitable packaging material.

4. Coding: Can You Keep Every Pack Traceable?

Date coding may look like a small part of the packaging process.

But if the factory is producing tens of thousands of packs every day, coding becomes a critical production function.

Depending on the product and market, the packaging may need:

• manufacturing date

• expiry date

• batch number

• lot number

• production code

A coding problem can create an unusual situation:

The packaging machine is running, but the finished product cannot be released.

Common problems include unclear printing, incorrect coding position, missing codes or incorrect date settings.

For a factory preparing for continuous production, coding should therefore be integrated into the overall packaging workflow rather than treated as an afterthought.

The operator should also have a clear procedure for changing product batches and verifying the code before production resumes.

5. Product Feeding: Can the Packaging Machine Get Enough Product?

This is one of the most important points.

A packaging machine cannot maintain stable output if the product supply is unstable.

Imagine a packaging machine capable of producing 60 bags per minute.

But the upstream feeding system supplies product inconsistently.

The packaging machine may repeatedly wait for product.

The result?

The machine has a theoretical capacity of 60 bags per minute, but the factory never achieves it in real production.

This is why the feeding system deserves as much attention as the packaging machine itself.

Depending on the product, the factory may use:

• Z-type elevators

• screw conveyors

• vacuum feeders

• hoppers

• buffer tanks

• pumps

• product conveyors

The objective is to create a stable product flow into the dosing system.

Think about the entire chain

Processing → buffer → feeding → dosing → packaging

If one part of this chain is unstable, the packaging machine cannot compensate for it.

6. Conveyor Transfer: Can Finished Packs Move Without Interruptions?

Once a bag is filled and sealed, the job is not finished.

The finished product still needs to move to the next stage.

This could be:

Packaging → inspection → counting → carton packing → case sealing → palletizing

If the conveyor system is poorly designed, finished bags can accumulate, fall over, become damaged or block the packaging machine.

This is especially important when several machines are connected.

For example, if the packaging machine produces 50 bags per minute but the downstream equipment can only handle 35 bags per minute, the line will eventually become unbalanced.

The solution is not always to slow down the packaging machine.

Sometimes the downstream process needs to be upgraded.

The key concept is line balance

A packaging line should be designed according to the capacity of the entire process, not the speed of one individual machine.

7. Operator Intervention: How Often Does Someone Have to Stop the Machine?

This may be the most overlooked weak point.

A machine may technically be automatic, but how often does an operator need to intervene?

Ask:

• How often does the operator adjust the machine?

• How often does the film need attention?

• How frequently are filling parameters changed?

• How often does the operator clear product from the sealing area?

• How often does the machine stop because of an alarm?

• How long does it take to restart after a stop?

If operators constantly need to adjust the machine, the factory may not really have a stable 24/7 packaging process.

The objective of automation is not simply to remove manual labor.

It is to reduce unnecessary human intervention while making necessary intervention easier and more controlled.

Why Theoretical Speed Is Not the Same as Real Production Capacity

This is one of the most important concepts when evaluating packaging equipment.

Suppose a machine is advertised at:

60 packs/minute

That does not necessarily mean the factory will produce:

60 × 60 = 3,600 packs/hour

in real production.

There may be:

• film changes

• product refilling

• bag-size changes

• cleaning

• coding adjustments

• material interruptions

• operator intervention

• quality checks

• machine alarms

• downstream conveyor limitations

Therefore, the number that matters to the factory is not only maximum speed.

It is stable usable output.

For example:

Theoretical capacity: 60 packs/min

Actual stable production: 48–55 packs/min

That difference may be much more useful when calculating production capacity, labor requirements and return on investment.

How to Prepare a Packaging Line for 24/7 Production

If your factory is planning to move toward continuous production, start with the process rather than the machine catalogue.

Step 1: Calculate the real production target

Define the required output per:

• hour

• shift

• day

• month

Then consider the expected future production volume.

Step 2: Identify the current bottleneck

Is the limitation coming from:

dosing → packaging → feeding → conveying → inspection → carton packing?

Do not automatically assume the packaging machine is the bottleneck.

Step 3: Test the actual product

Product characteristics matter.

Two products with the same target weight may behave completely differently during feeding and dosing.

A factory should ideally test the actual product before finalizing the machine configuration.

Step 4: Test the actual packaging material

The film or pouch is part of the packaging system.

Its dimensions, material structure, thickness, printing and sealing characteristics can all affect machine performance.

Step 5: Plan for changeovers

If your factory produces several SKUs, 24/7 production does not mean running one product continuously.

The factory may need to switch between:

100 g → 250 g → 500 g → 1 kg

The changeover process therefore becomes part of production efficiency.

A machine that runs quickly but requires a long changeover may not deliver the expected daily output.

Step 6: Plan maintenance before problems occur

Continuous production does not mean ignoring maintenance until the machine breaks.

Wear parts, sealing components, sensors, belts and other consumable components should be monitored and replaced according to the machine's maintenance requirements.

It is also sensible to keep critical spare parts available.

The 24/7 Question Is Really a System Question

A food factory does not become 24/7-ready simply because it buys an automatic packaging machine.

The entire system needs to support continuous production.

Think of it as seven connected links:

Filling accuracy

↓

Film feeding

↓

Sealing

↓

Coding

↓

Product feeding

↓

Conveyor transfer

↓

Operator intervention

If one link repeatedly causes downtime, the entire packaging line can suffer.

This is why packaging automation should be evaluated as a complete process rather than as an isolated machine.

Final Thoughts

Before investing in a higher-speed packaging machine, ask a more important question:

What is currently stopping my factory from producing more?

Maybe the problem is dosing accuracy.

Maybe film feeding is unstable.

Maybe sealing quality deteriorates during long runs.

Maybe the product feeding system cannot keep up.

Or perhaps the machine itself is fine, but operators are constantly required to make manual adjustments.

Finding these weak points first can prevent a common mistake:

buying a faster machine without fixing the bottleneck around it.

For food factories preparing for larger orders and longer production hours, the goal should not simply be maximum machine speed.

The goal is stable, repeatable and maintainable production.

At Keypack Intelligent Technology, packaging solutions can be configured around different products, pack sizes and production requirements, including weighing and dosing, VFFS packaging, premade pouch packaging, conveying and inspection systems.

If you are planning to increase production hours or move toward multi-shift production, start with the actual numbers: product, pack size, packaging material, current output and target output.

Those five parameters are usually a much better starting point than simply asking for the “fastest packaging machine.”
