What is a Folder-Gluer Packer and Do You Really Need One?

It was a Monday night when I sat back staring blankly at my computer screen after a long first day of work at IMPACK where it dawned on me:

What the heck is even a folder-gluer packer?

Hi! My name is Hani and I am new to IMPACK myself. Being new to the industry, I have the same questions you do about those fancy, complex machines that I want answers for.

I then thought…who else would be better to ask than someone who has worked in the field, day-to-day with those packers for a long time.

Stefan Badertscher, Director of Sales and Marketing at IMPACK, has close to a decade’s worth of experience with packing help, semi-automated and fully-automated packers. Backed with years of practical experience as a Mechanical Engineer, and a high level of sophistication in this industry, I was confident that I would be in good hands for answers.

So, I set up a meeting with Stefan and started asking question after question until I finally understood what a folder-gluer packer is and what companies it is best suited for.

So come along with me as we embark on this journey together!

In this article, we will be examining what a folder-gluer packer is, who needs a packer and why do you even need one.


What is a Folder-Gluer Packer?


See, the answer to this question varies based on who you ask, but even more interestingly, it depends on how long you speak to them.

All of us business people within this monstrously growing industry like to dub our complementary folder-gluer equipment as the coveted: packer.

But the reality is that not every machine around a folder-gluer is a packer and not every packer is a solution for a folder-gluer.

It all depends on your individual needs, specific circumstances, and a set of intertwined factors.


Some define their traditional packing stations/tables as packers.

Many others define their box turners as packers.

Most define their packers as packers.


So, then, what is a packer?

I will break down the true difference by making a very clear distinction.


Packing Help Stations/Tables


Definition: A traditional packing process using “pick and place stations” with tilting tables and without case management. Otherwise known as “packing help” or “packing aid.”

The drawing below schematically shows the organization of the packing station(s):

On the most basic level, you would have a table locally-made from wood or stainless steel that is tilted at an angle to prevent the boxes from falling when placed into the case. Most clients we see have a tilting table where when the case is full, they can push it so that it tilts and then they can eject it straight.

One step further is having additional packing aid by adding a conveyor and a box turner. This would now become a right-angle packer.

The conveyer would allow you to slow it down and give the packing person more time by allowing more boxes within the same time-lapse.

The box turner allows you to turn, accumulate and pack by hand, but you can only pack so much with your own hands. The operator would lift those limited small batches, place them inside the case and then reposition themselves to start the operation again.

Without turning, your boxes would come out standing up and then you need to turn them 90 degrees to put them into the case. Hence why the box turner comes into play.

At some point – yes – you do start to pick up speed where you can take a whole row of boxes at once, lift it in the air and pack it into the case, but you still need to do the lifting, case ejecting and packing yourself. There is absolutely no case management involved.

So in reality, the right-angle packer is merely a box turner. It would turn boxes by 90 degrees. Nothing more, nothing less.


     ★ Quick summary: The most common “packing help stations” have a basic conveyor, a tilting table and sometimes a box turner which is the packing help/aid. No case management involved.




Definition: A modernized packing process that utilizes leading, cutting-edge machinery technology to streamline case ejection and manage case handling.


IMPACK’S Ergosa: A semi-automatic packer with the performance of an automatic packer.


What makes a packer, a packer is really case management.

Anything without case management is simply a packing help or aid. With the case management feature that a packer offers, you can streamline your case ejection process so that your packing person is doing the packing and not case management, case taping or case pushing.

Once your case is full, all you do is push a button. That ejects the case semi-automatically or fully-automatically and you can take a new case. This is where you leverage to your advantage a lot of precious seconds, man-power and more output.

For example, If you’re packing 2-3 cases per minute with the automated case ejection, then you save 5 seconds per case which is 10-15 seconds per minute. This represents 15-25% more time for packing which thereby translates into more productivity on the whole packer line.

The case management allows you to add case handling to the process which means you can adjust the machine to a custom-case height that is ergonomic and productive — without the need of your packing person(s) to do any case management.


     ★ Quick summary: A Packer is when you have optimized your packaging area and included case management for taping, pushing and ejecting.


Now that we have laid this out clearly, who actually needs one of those packers?


Who Needs a Folder-Gluer Packer (& Why?)


In the quickest way possible:

If you’re considering equipment around folder-gluer lines, there are 3 questions to ask yourself:

  1. What does your production look like today?
  2. What machines do you already have?
  3. How many shifts do your operators work?


Question #1: What Does Your Production Look Like Today?


Knowing what your products are, what volumes you produce, the speed at which you produce and the level of potential you have realized (or not) is the first step.

What does this all mean? Put simply, choosing the right machine depends on the thing you produce and how you go about producing it.

Your Products

This includes the type, material, varnish, size, shape and thickness of your boxes.

Are you producing only folding carton or folding carton and corrugated/micro-flute?

And what type of boxes are you producing? 4-corner, 6-corner…etc.

Are you also producing crash-lock/auto-bottom boxes?

Knowing what you produce, how you produce it and your case-packing configuration will give you a very good understanding of what machine is right for what production.

Your Volume & Speed

Production volume is just a cool word for the number of boxes per folder-gluer line. Are you producing small volumes like 20,000-40,000 boxes/setup, larger volumes like 100,000-150,000+ or somewhere in the mid-range of 40,000-100,000?

The smaller your production volume is, the higher the % of setup time relative to actual production time. And the lower your production time, the slower your gluer speed would be because the operator has no time (or it is not worth the time) to tune your gluer to run faster.

Let’s take an example: If your setup takes you 15 minutes to run a box at 40,000 per hour, and you produce 10,000 boxes, then your production is 15 minutes. This results in a total production time of 30 minutes. At this point, you might as well just use the hand-packing mode with 1-2 minutes setup and run at 20,000 per hour.

So, what I want to draw your attention to is that there’s this tipping point where the setup time becomes less important because your production volume is high enough that your operator(s) and management will want to take the time to tune your gluers to the maximum speed.  

Your Potential

When I speak of potential, I am talking about whether you’ve pushed your folder-gluer to its maximum capacity.

Are you at the point where you can no longer produce more because you’ve reached your full capacity?

If you shouted “Yes” at the top of your lungs, then keep reading.

Now my question is Why?

If the reasons come down to limited shifts or man-power then we can agree that you’re capable of producing more, but you aren’t doing so…due to human limitations.


Question #2: What Machines Do You Already Have?


Today, a few companies use packing help stations/tables, most use box turners (right angle packers) and many are somewhere between semi-automated to fully-automated packers.

Are you in a situation where your boxes are coming out from your folder-gluer followed by your operators taking your boxes from there and putting them into some case by hand then pushing it somewhere where someone tapes it?

That was a mouthful! But if you answered “Yes,” then you probably are in the early stages of production where you have nothing behind the folder-gluer.

💡 Here’s a quick helpful tip: By simply adding another conveyor, you can slow down the speed compared to the exit of the gluer. Why so?

You can think about it in terms of density. When you increase your box density per meter of conveyor, you allow more box accumulation per meter of your conveyor. This leads to more boxes in the same time-frame.


More boxes mean more time for your packing person.

More time means the process is far more relaxed.

More relaxed means less room for error.


Assessing your current folding-gluing lines and any existing equipment around them is the second step. Sometimes all you need is some modifications such as adding more modules to the folder-gluer or having to go through the headache of changing the gluer altogether to a more recent one.

The orientation of the boxes in the case may vary because of style or format reasons. Take for example, the IN Box Turners we design here at IMPACK shown in the image below. They allow boxes to be rotated by 90°. The Box Turner IN1 can be installed directly on the folder-gluer compression belt – the simplest and most economical way to turn your boxes.

I love this article written by Jeff on PostPress that talks about choosing the right folder-gluer because it is a great place to start by looking at the 3 most important points that you need to know when choosing the right gluer.

An up-to-date gluer will usually imply a better automated, smoother and quicker setup that requires less manpower. Problem solved!

Let’s move on to the last question.


Question #3: How Many Shifts Do Your Operators Work?


If you only have someone working one shift, 5 days a week on 1 folder-gluer line then you’re likely a family-owned business or a small-scale business owner.

Let’s be honest…in those types of situations, you don’t really need a new folder-gluer packer, let alone go down the full automation route.

Instead, you can invest in more ergonomic stations so people can enjoy coming to work. In addition, you can ramp up your productivity by getting an additional conveyor and two tilting tables with taping machines.

On the other hand, if you own 1 or 2 folder-gluers then you probably are in the range of doing a bit of everything but nothing too large in terms of volume or run-sizes. If this rings true to you, it could be lucrative to take your first step towards semi-automation.

Now, if you own 3 or more folder-gluers with dedicated lines, and you do a diverse array of multi-format boxes, then you are looking at a super sophisticated machine that is bigger, better and more specialized.


Do You Really Need a Folder-Gluer Packer?


So, should you say “Yes” to a packer or “No?”

It all boils down to what your needs are.

Here is the concrete answer you’ve been waiting for:

If you can no longer increase the capacity of your folder-gluer because you have pushed your gluer to the limit, then ask yourself: Where exactly is the bottleneck taking place?

If the bottleneck is at the gluing and you have 1 packing person, then a simple packer will not help you. However, a fully automatic packer could remove that one person and place them into higher value activities if the production volumes are fitting. 

For example: Let’s say you are producing 50,000 boxes per hour with 1 packing person, and you’ve reached the maximum speed of your gluer, this means that you cannot run faster with the gluer no matter what you do. Adding another person has no effect on the speed because the gluer has already reached its limit.

Therefore, you probably do not “need” a packer for small production volumes. That said, a packer could help for ergonomic reasons and you have to evaluate what ergonomics is worth for your company.

On the other hand, if you have large production volumes of 150,000 cartons or more, a fully automated packer might be a lucrative solution.

If the bottleneck is at the gluing, and you have 2 people packing, then you can reduce 1 or 2 people with the help of a packer.

For example: If your gluer is running at a speed of 50,000 boxes per hour with 2 people working hard to pack at that speed, and you already know that the folder-gluer has hit its limit, then you might want to consider adding a packer.

The packer would help you reduce 1 or 2 people and continue producing at the same folder-gluer speed. This means that you either need no packing person remaining or that the remaining person is packing twice as fast as before.

If the bottleneck is at the packing then whatever you do with the packer, it would be very helpful.

For simplicity, let’s take the same example: Your gluer is running at a speed of 50,000 boxes per hour with 2 people working hard to pack at that speed.

This time though, you know the folder gluer can run at 80,000 boxes per hour. In this specific situation, you may want to find a packer that helps you achieve your full potential of 80,000 boxes per hour either fully automatically or with 1 person only.

On the other hand, if you’re always in the small-volume ranges of 20,000-40,000 boxes per setup, then you typically won’t reach your folder-gluer’s top speed and this is where packing help stations/aid might be of interest to you for ergonomic reasons or organizational efforts.

If you’re one of those people who skip straight to the end, here’s the quick takeaway:

The real tipping point between deciding to go from a gluer only to adding a packer or not is the setup time i.e. if your gluer could go faster and the packing people can follow, then this is where tuning your gluer only would be a better first option than going for a packer.

However, if your gluer is far from reaching its full potential and your 2 packing persons are exhausted from working hard each day, then this is the best indication that it is time to explore some options of packers.
