What Does Case Erector Mean?

Actually, a case erector is a case former machine, it converts the case blanks into fully erected, bottom-sealed cardboard boxes or folding cartons.

It is a kind of packaging equipment widely used in logistics, e-Commerce, and distribution industries.


Corrugated Box Erector

The paper carton erecting machine picks up a case blank from the blank magazine, then completes a series of processes such as case forming, bottom flaps folding, and bottom sealing, then finally outputs a cardboard box or folding carton.

The outfeed corrugated box/folding carton is open at the top, and the other sides are sealed, they are ready for product loading by packaging machines or human hands.


Types of Carton Erector

Case erecting equipment has many different classifications, the following classifications are common.

  • Case Type

There are 2 types, one is a corrugated box erector, and the other is a folding carton erector;

  • Degree of Automation

3 types are optional, manual, semi-automatic, and automatic;

  • Erecting Orientation

Vertical case erectors & horizontal case erectors are two different types.

Cardboard Box Erectors

Cardboard box erectors erect corrugated boxes, after erecting, they fold the corrugated boxes’ bottom flaps, then seal the bottoms with tape or glue.


Corrugated boxes are made of corrugated cardboard through die-cutting, creasing or gluing, etc.


Industrial Corrugated Box

The following types of corrugated boxes are common on the market:

  • AFM (All Flaps Meet)
  • HSC (Half Slotted Case)
  • RSC (Regular Slotted Case)

Among them, RSC is the most popular.


Regular Slotted Case

If your cases are special, please contact us first, and we will customize a suitable carton box erector machine for you.

Folding Carton Erector

A folding carton erector is a common packaging machine.

After picking up the folding carton blank from the blank magazine, it then separates & shapes the carton blank, folds the bottom flaps, closes the bottom, and finally outfeeds the folding carton.

The folding carton is open at the top after coming out from the erector, then a downstream packaging machine or human hand can load the product into it easily.


Unlike the cardboard box, the folding carton’s main material is paperboard, which is suitable for packing daily necessities;

The cardboard box’s main material is corrugated paper, which is suitable for packaging industrial products.


2 types of folding carton erectors are optional for your choice:

Tuck End Carton Box Erector

It is useful for erecting straight tuck end cartons and reverse tuck end cartons.



The following video shows the workflow of the tuck end carton erector.

Automatic Carton Erector

For the automatic case erector, you just need to place the cardboard box or folding carton blanks in the magazine in advance, no need for other manual intervention.

With reference to the above video, we summarize the workflow of the automatic box erector as follows:

  • Case Blank Pickup
  • Case Shaping
  • Case Erecting
  • Case Transmission
  • Case Sealing

Semi Automatic Case Erector

Please watch the following semi automatic carton erector’s demo video for reference first.

For semi auto carton erector, a worker picks up a box blank and shapes the blank to fully erected status.

And then, place the erected case on KDF (Knocked Down Flat) stand for bottom flaps folding, and push it to the top & bottom sealing station.

After the photoelectric eye detects the carton, the pressure sensitive tape head automatically seals the top and bottom of the carton.

Factors to Consider in Carton Erector Sourcing

If you are still struggling with how to choose the right carton erecting machine, the following content may help you to escape the struggle.

To buy a suitable carton erecting machine, you must first clarify the following questions.

Case Types

Most carton erecting machines on the market are suitable for processing regular slotted cases (RSC), and many potential customers search on Google with the keyword RSC case erector.

If your cases are regular slotted cases, there are many suitable carton erecting machine manufacturers for your choice.


Regular Slotted Case

If your cases are overlap slotted cases or half slotted cases, the optional case erecting machine supplier will be much less.

Case Sizes

Secondly, you need to know the size of your case.

The length, width, and height of your case should fit the case erecting machine’s blank magazine, thus the case erecting machine can handle your cases.


Case Corrugating Quality

According to our previous experience, the quality of case corrugating affects the corrugated box erector’ effect.


Some customers also found this problem, and after replacing the poor corrugating cases with better ones, they successfully solve the problem.

In view of this, we suggest you communicate with your corrugated box suppliers and remind them to take care of corrugating quality.

If possible, carry out an inspection before large-scale production.

Erecting Speed

Generally speaking, a standard vertical carton erector forms 7-10 cases/min, and a standard horizontal corrugated box erector forms 15-20 cases/min.

If you have higher requirements for speed, we suggest you purchase a horizontal high speed case erector, its speed could reach 40-50 cases/min.

Sealing Types

Tape sealing & hot melt glue closure have their own advantages & disadvantages.

  • Pros & Cons of Tape Sealing
  1. Lower price;
  2. Less power consumption;
  3. Easier maintenance;
  4. Tape quality affects sealing quality;
  5. Tape sealing can’t keep up with high-speed case forming;
  6. A roll of tape runs out faster than a tank of glue, more frequent tape replacement.
  • Pros & Cons of Hot Melt Glue Closure
  1. Higher efficiency;
  2. Glue replacement frequency is lower than tape replacement;
  3. Glue may block the hoses & nozzles;
  4. Over-spraying may occur, and more cleanup efforts.

You can decide which type to choose based on the above comparisons.

Automation Degree

As mentioned before, there are 3 types of case former machines according to the degree of automation, manual, semi automatic, and automatic.

Manual case former machines are rare on the market now, semi automatic & automatic case former machines are common.

If your budget is sufficient, in favor of fast case forming speed, and your local labor cost is high, it’s better to choose a fully automatic cardboard box case erector without any hesitation;

If your budget is limited, no special requirement for case forming speed, and your local labor cost is within an acceptable range, then you can choose a semi automatic carton erector.

What Does a Case Sealer Do?

The case sealer’s function is to close or seal corrugated boxes, the medium for sealing includes hot melt adhesives, BOPP tapes, and water activated gum tapes.


Water Activated Gum Tape

As for the box taping machine, its core component is the pressure sensitive tape head.


Pressure Sensitive Tape Head

When the carton presses the tape applicator, the applicator is triggered to seal the box.

After the sealing tape reaches the preset length, the blade on the applicator cuts off the tape to complete the sealing process.


The adhesive dispenser is essential for the hot melt glue case sealer, it sprays glue for bonding the carton’s inner flaps & outer flaps together.


Case Erector and Sealer

The following video presents the carton erector and sealer’s workflow.

As you can see, there is a belt conveyor between the carton erector and sealer, and a worker can stand by the conveyor, loading the product into the corrugated box.

This scenario is common in the E-commerce industry, as shown in the following video:

If you have requirements for packaging speed and hope to reduce labor, you can link the auto case erector and sealer together with the case packer, we call it ‘case erector packer sealer’.

Some manufacturers supply this type of all-in-one machine, including our SiroSilo.

Once you plan to purchase a packaging line that includes a case erector packer sealer, welcome you to send us an inquiry on this website, and we will reply to you within 1h.

Case Erector Bag Inserter

Some customers contact us to purchase a combined case erector and bag inserter because they do packaging for biscuits, solid oil, edible oil, nutritional powder, and other products.

The combined box erector and bag inserter is formed by linking the case erector and the bag inserter by a conveyor belt.
