What Does Case Erector Mean?
Actually, a case erector is a case former, 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, distribution industries.
The carton erector picks up a case blank from the blank magazine, then completes a series of processes such as case forming, flap folding, and case bottom sealing, and finally outputs a cardboard box or folding carton.
The output cardboard 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 Case Erector
Carton erecting machine has many different classifications, the following classifications are common.
- Case Type
There are 2 types, one is corrugated box erector, the other is folding carton erector;
- Degree of Automation
3 types are optional, manual, semi automatic, and automatic;
- Erecting Orientation
Vertical carton erector & horizontal carton erector are the 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.
The following types of corrugated boxes are common on the market:

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 with tape or glue, and finally outfeeds the folding carton.
The folding carton is open at the top when coming out from the erector, then downstream packaging machine or human hand can load 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, horizontal folding carton erector & vertical folding carton erector.
In fact, the vertical folding carton erector originates from the vertical cartoning machine.
Remove several stations on the vertical cartoner, then the vertical cartoner changes to a vertical folding carton erector.
Automatic Case Erector
For the automatic box erector, you just need to place the cardboard box or folding carton blanks in the magazine in advance, no need for other manual intervention.
The automatic box erector complete the following steps one by one:

For semi automatic case erector, a worker picks up a box blank, shapes the blank to fully erected status.
And then, place the erected case on the erector for bottom flaps folding, push it to the bottom sealing station.
After the photoelectric eye detects the carton, the pressure sensitive tape head automatically seals the bottom.

Factors to Consider in Carton Erector Sourcing
If you are still struggling with how to choose the right packaging box erector, 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).
If your cases are regular slotted cases, there are many suitable carton erecting machine manufacturers for your choice.
If your cases are overlap slotted cases or half slotted cases, the optional carton 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 packaging box erector’s blank magazine, thus the packaging box erector can handle your cases.
- Case Corrugating Quality
According to our previous experience, the quality of case corrugating affects the packaging box erector machines’ effect.
Some customers also found this problem, 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, remind them to take care of corrugating quality.
If possible, carry out inspection before large-scale production.
- Erecting Speed
Generally speaking, a standard vertical carton box erector forms 7-10 cases/min, and a high-speed vertical carton box erector’s speed is 15-20 cases/min.
The difference is not too big.
If you have higher requirements for speed, we suggest you purchase a horizontal carton box erector, the speed may reach 30-40 cases/min.
- Sealing Types
Tape sealing & hot melt glue closure have their own advantages & disadvantages.
- Pros & Cons of Tape Sealing
- Lower price;
- Less power consumption;
- Easier maintenance;
- Tape quality affects sealing quality;
- Tape sealing can’t keep up with high-speed case forming;
- A roll of tape runs out faster than a tank of glue, more frequent tape replacement.
- Pros & Cons of Hot Melt Glue Closure
- Higher efficiency;
- Glue replacement frequency is lower than tape replacement;
- Glue may block the hoses & nozzles;
- Over-spraying may occur, more cleanup effort.
You can decide which type to choose based on above comparisons.
- Degree of Automation
As mentioned before, there are 3 types of case formers according to the degree of automation, manual, semi automatic, and automatic.
Manual case formers are rare on the market now, semi automatic & automatic case formers 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 case former 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 case former.
What Does a Case Sealer Do?
The case sealer’s function is to close or seal corrugated boxes & folding cartons, the medium for sealing includes hot melt adhesives, BOPP tapes, and water activated gum tapes.
For the tape sealing case sealer, its core component is the pressure sensitive tape head.
When the carton presses the tape applicator, the applicator is triggered to seal the box. After sealing 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 closure case sealer, it sprays glue for bonding the carton’s inner flaps & outer flaps together.
Case Erector and Sealer
The following video presents the case erector and sealer’s workflow.
As you can see, there is a belt conveyor between the case erector and sealer, and a worker stands by the conveyor, loading the product to the corrugated box.
This scenario is common in the E-commerce industry.
If you have requirements for packaging speed, hope to reduce labor, you can link the 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.
