What Are Folder-Gluer Packaging Equipment & Which Machine is Best For You?

Featured Image

If you’ve been searching for ways to improve your folder-gluer's productivity and speed up your packing, you've probably come across several solutions.

Collecting Tables, Semi-Automatic Collectors, Packing Help Stations, Packers, and Stackers are just some examples of the many solutions on the market.

And different packaging equipment suppliers offer distinct solutions with varying features, capabilities, and levels of automation.

Having all those options is great, but the reality is that companies are so busy with their day-to-day operations that they do not have the time, or energy, to reach out to the sales team of multiple companies to assess their options.

Unfortunately, this leads companies to choose the most convenient partner rather than the best fitting partner.

And the result?

Well, companies quickly realize that this partner is a bad apple or that their solution does not do what they expected it to do.

And we have seen this time and time again.

At IMPACK, we’re committed to providing box manufacturers with all the information they need to know to make the most educated decision for their production. 

Even if that means not choosing IMPACK

What Are Folder-Gluer Packaging Equipment?

The Prefio, MFA, Virtuo and Everio machines

Folder-gluer packaging equipment are the packing systems and peripheral devices that can be added on, and around, a folder-gluer.

Packing systems are the automation solutions added to a folder-gluer. For example: Folder-gluer packers and stackers

Peripheral devices are the additional solutions that can complement the packing systems added to a folder-gluer. For example: Pre-feeders, box turners, batch inverters, and counting and separating devices.

These packing systems and peripheral devices altogether makeup the 4 families of packaging equipment: 

  1. Pre-feeders.

  2. Pre-packers.

  3. Packers.

  4. Stackers.

The image below shows you the organization of the 4 families of packaging equipment around a folder-gluer.

Each of those 4 families includes distinct solutions with varying features, capabilities, and levels of automation

We classify those levels of automation into 4 categories:

  1. Manual packing.

  2. Semi-Automated packing.

  3. Automated packing.

  4. Fully-Automated packing.

Now that we’ve clearly defined the broad term “folder-gluer packaging equipment,” and what it encompasses, let’s explore each family individually and examine the solutions they have to offer!

The 4 Families of Folder-Gluer Packaging Equipment

What is a Pre-Feeder?

ezgif.com-gif-maker - 2021-08-10T005355.653

IMPACK’s Prefio: One of the only pre-feeders on the market for corrugated board.

A pre-feeder is a unit installed in front of a folder-gluer, and before the feeder, that continuously feeds the folder-gluer’s feeder. 

More specifically, a pre-feeder is installed at the beginning of the folder-gluer as shown in the image below. 


A pre-feeder is installed in front of a folder-gluer and before all other packaging equipment.

💡 Purpose: Pre-feeding equipment allow the folder-gluer’s feeder to run at a higher speed, with a perfect stack height, and without damaging the box blanks. 

IMPACK’s pre-feeder is the Prefio: The smallest pre-feeder for corrugated board on the market.

What is a Pre-Packer?

MFA and IN3

IMPACK's MFA Batch Inverter and the IN3 Box Turner installed after the folder-gluer and before the packer (Both units are pre-packers).

A pre-packer is a unit installed right after the folder-gluer, and before the packer, as depicted in the image below. 

Most often, several pre-packer units are installed after the folder-gluer. 

Those pre-packers include box turners, batch inverters, and counting and separating devices


A pre-packer is installed right after the folder-gluer and before a packer.

💡 Purpose: Pre-packing equipment allow you to prepare the shingle (overlapped stream of boxes) in the right orientation before it enters the case packing process. This way each shingle can be packed into the cases with the right orientation and in the most efficient way possible. 

IMPACK’s pre-packers are the IN Series box turners, MFA and Alterna batch inverters, and the INTRO, OBP, and OBS counting and separating devices.

The only exception is if you own IMPACK’s Ergosa A packer which already includes a built-in IN2 or INH box turner as part of the Ergosa A package.

As for the other types of pre-packing equipment, it all depends on your production, box sizes, product mix, and format restrictions. 

A batch inverter is typically added to a packer when you are producing high volumes of crash-lock/auto-bottom boxes (~30-50 million per year or less in some situations).

A counting and separating device is added to a packer if you have an IN2 or IN3 box turner and when the kicker counter from the folder-gluer is lost in the shingle after the turn.

IMPACK's new INH box turner is built specifically to keep this kicker counter visible, thus removing the need for an alternate counter solution!

What is a Packer?


IMPACK’s Ergosa C: A high-performance and versatile semi-automatic packer with the performance of an automatic packer that offers 3 packing modes.

A packer is a unit installed behind a folder-gluer and after the pre-packer(s). 

That is, a packer is installed at the end of the flow of the gluing line.

A packer is installed behind the folder-gluer and after the pre-packer i.e. after all other packaging equipment.

💡 Purpose: A packer utilizes a modernized packing technology that allows you to dramatically improve the efficiency, ergonomy, and productivity of how you pack your boxes into cases by offering you automated case management capabilities. 

In other words, a packer optimizes your case packing process by automating certain actions involved in the case packing.

IMPACK’s packers are the Ergosa packer and the Virtuo packer.

What is a Stacker?


IMPACK’s Everio: A fully automatic stacker to stack and band your boxes coming from folder-gluer(s) or rotary die cutters.

Just like a packer, a stacker is installed behind a folder-gluer and after the pre-packer(s). 

More specifically, a stacker is installed at the end of the flow of a typical gluing line as demonstrated in the image below.

A stacker is installed behind the folder-gluer and after the pre-packer i.e. after all other packaging equipment.

Depending on your production processes, you either pack your boxes into cases (i.e. case packing) using a packer or stack your boxes to be banded/strapped together (i.e. box bundling) using a stacker.

In other words, you would either have a packer or a stacker after the pre-packer(s) but some clients do both processes on the same folder-gluer.

💡 Purpose: A stacker utilizes a modernized bundling technology that allows you to bundle your boxes vertically and then send them for banding/strapping.

IMPACK’s stacker is the Everio stacker.
