This page will focus on folding carton erectors and will also cover cardboard box erectors, please enjoy the following content directory.

Types of Folding Cartons

The material of folding cartons is 200-350g single-layer white paperboard, grey paperboard, kraft paper, coated paper, etc.


White Paperboard

Paperboard is printed first, then pass through machines for die-cutting, gluing, and scoring to create folding cartons.

Because it consists of a single-layer paperboard, the folding carton’s bearing weight is relatively low, so it is suitable for packing light items.


A folding carton is foldable when not packing contents, which can save storage and transportation space. It is the most popular paper packaging box on the market.

Different types of folding boxes are useful for packing different types of products. The most common folding boxes on the market mainly include the following 4 types:

Straight Tuck End/Top (STE)

As you can see in the photo below, the straight tuck end box’s top tuck flap & bottom tuck flap are on the same side.


The straight tuck end box is one of the most popular cartons on the market, it is visible in many industries, such as health & beauty, cosmetics, etc.

Reverse Tuck End/Top (RTE)

With reference to the following picture, you know the reverse tuck end box’s top tuck flap & bottom tuck flap are on the opposite side.


The reverse tuck end box is ideal for packaging lightweight items, its assembly is easy. As it keeps flat for storage & transportation, saves your warehousing and logistics fees.

What’s more, 1 paperboard sheet converts more reverse tuck end boxes than straight tuck end boxes, thus the price of each reverse tuck end box is lower than the straight tuck end box.

Tuck Top Snap Lock Bottom (TTSLB, also called 1-2-3 Bottom Box)

Please see the reference photo below:


Folding the snap lock bottom box includes 3 steps:


  • Fold the female bottom closure panel
  • Fold two closure flaps
  • Fold the male bottom closure panel and insert it into the female bottom closure panel

Such a 1 2 3 bottom box is quite suitable for packing slightly heavy products, as its bottom base is really really sturdy.

Industries like health and beauty, toys, food, and pharmaceutical often introduce such boxes to package items.

Tuck Top Auto Bottom (TTAB)

Tuck top auto bottom box is also called auto-lock bottom or crash bottom box.


As such auto bottom box with glue tabs, its bottom base can bear more weight, it’s also ideal for slightly heavy content packaging.

Due to pre-glued tabs, the price of auto bottom boxes is higher than bottom tuck and snap lock bottom boxes.

What is Folding Carton Erector?

The function of folding carton erectors is to erect, square & shape, and seal small folding carton boxes with top openings.


This kind of small folding carton is common in packaging, printing, food, and edible industries, it is suitable for packing cereals, snacks, household goods, personal care products, cosmetics, light bulbs, hardware, etc.


Till now, SiroSilo has developed several types of small box erectors, and the following types of folding carton boxes are producible.

  • Tuck End Box
  • Snap Lock Bottom Box

The content below will introduce these 2 types of small box erectors one by one.

Tuck End Box Erector


The tuck end box erector mainly forms straight tuck cartons & reverse tuck cartons.

When these straight tuck & reverse tuck end boxes come out from the carton erector, their tops open outward for the follow-up product loading.


Straight Tuck Carton


Reverse Tuck Carton

In lighting, electrical appliances, e-commerce, 3C, handicrafts, beauty, cosmetics, toys, food, and other industries, such a little carton erector is widely applied.


It has a compact footprint, equips with casters, can move flexibly for mobile use, or work together with other packaging equipment to form a packaging line.



Regarding SiroSilo’s mechanical & electrical integration tuck end box erector, it adopts mechanical linkage & pneumatic control, lower power & energy consumption, cuts your electricity bills every shift;

As PLC controls the machine operation, every motion is accurate, ensuring the carton forming quality.


You can set parameters on the touch control screen, which is simple & convenient, and the English interface is available.


The following video presents this little carton erector’s English interface, please watch it for reference.

In addition, we install several photoelectric eyes on this small box erector machine.

These eyes monitor the motions of various parts, such as detecting the carton status & carton miss, ensuring carton forming is smooth.


Photoelectric Eyes


Speaking of the carton forming, it includes the following steps:

  • Carton Blank Pickup
  • Bottom Dust Flap Folding
  • Bottom Closing Panel Folding
  • Bottom Tuck Flap Insertion
  • Erected Carton Output


Refer to the video below, let me explain the workflow of our eCommerce carton box erector to you.

The vacuum sucker picks up the carton blank from the magazine, squares the blank into shape, then places it in a row of lugs.


The chain drives the carton forward, and the plows fold two dust flaps first, then fold the bottom closure panel.

Finally, the air-controlled tucker inserts the bottom tuck flap into the carton, and a fully-erected & bottom-sealed carton catches your eyes.


Then, the fully-erected & bottom-sealed carton moves forward to the outlet, directly into the downstream packaging equipment, or into the pre-placed collection container below.


The tuck end carton erector machine just follows these processes, then repeats them over and over again.

1 2 3 Bottom Box Erector


With regard to the 1 2 3 bottom box erector, it converts carton blanks to 1-2-3 bottom boxes.


When the formed snap lock bottom box comes out from the small box erector, its top closure panel & dust flaps are open for product filling.


As shown below:




SiroSilo 1-2-3 bottom small box erector consists of the following parts:

  • Control Console
  • Electric Cabinet
  • Alarm Light
  • Carton Blank Magazine
  • Carton Erecting Unit
  • Bottom Locking Unit
  • Carton Outlet

Turn on the power button on the control console, and click “Start” on the touch screen to run the machine.


Two vacuum suction cups suck a carton blank from the magazine, they absorb the bottom of the carton blank and move to the carton forming station.


During the carton blank’s natural falling process in the magazine, the falling contact area & friction force is small.

With the block-shaped strip guiding the carton blank falling, the falling process is smoother.

By adjusting the feed rod & lead screw of the carton blank magazine, you can change the magazine’s length & width, thus the magazine can fit different carton sizes.



After the carton blank arrives at the carton forming station, the photoelectric eye detects the carton blank and feeds a signal to the PLC.


The PLC sends commands, and two vacuum suction cups absorb the upper part of the carton and apply an upward pulling force to the carton.

Two reverse pulling forces (upper & lower) erect the carton.


After erecting & shaping the carton, the next step is to lock its bottom, the bottom locking unit undertakes this task.

The bottom locking unit folds the female bottom closure panel first, then folds the closure flaps.

Finally, the tucker inserts the male bottom closure panel into the female bottom closure panel.


With reference to the following video, you can better understand such small box erector’s workflow.

After bottom locking, the tucker will apply another force to the carton, and push the carton out of the small box erector.


If you want to customize your desired 1-2-3 bottom box erector machine, please send us an inquiry on this website, and we will get back to you.


Cardboard Box Erectors

The cardboard box is die-cut from corrugated cardboard, and the cardboard box erectors play an important role in corrugated box packaging design.

It first picks and places the corrugated box blanks, then erects these blanks into rectangular shapes with open tops and bottoms, and finally seals the bottom major (outer) and minor (inner) flaps of the erected tubes for subsequent loading.


According to the degrees of automation, corrugated box erectors are divided into:

  • Semi Automatic
  • Fully Automatic

Based on sealing medium, cardboard erectors have two kinds:

  • Case Erector Tape
  • Case Erector Glue

There is also a box erector robot, which has a robotic arm to pick and place the box blank, it is different from the conventional type.


The cardboard box erector machine could run independently or seamlessly integrate into a carton packaging line with the carton sealer and case packer.

Automatic Cardboard Box Case Erector

The automatic cardboard box case erector automatically absorbs and places the carton blanks, shapes them into rectangular tubes with open tops & bottoms, then folds the bottom flaps, seals the bottom, and then transports the completely erected and bottom-sealed case to the case packer.

Such automatic case erector machine adopts PLC control and graphic touch screen HMI to set parameters, one machine could finish the whole process of blank picking & placing, case shaping, flaps folding, and bottom sealing.

Semi Automatic Carton Erector

Unlike the automatic box erector machine, the semi automatic carton erector requires manual erecting of the carton blank, turning the carton blank into a rectangular shape with top and bottom openings.


Rectangular Shape

And then, manually place the partially formed box into the pocket of the semi auto carton ererctor to complete the bottom flaps folding.



After loading the products, push the fully-erected & bottom-flaps-folded carton into the sealer to close its bottom or its top & bottom.

Box Erector Robot

Programmable 4-8 CPM

The speed of a box erector robot may be lower than a conventional case erector, but it could automate the case erecting of multiple sizes at the same time.

This robotic case erector introduces an industrial vision system to identify different cartons and collaborates with multiple carton blank magazines to achieve continuous erecting of multiple sizes of cartons.

If your carton size is single and the speed requirement is high, then choose the conventional case erector; if your carton size is various, then choose the robot case erector.

Fixed Program 30CPM

With three servo motors driving the robotic arm of such a box erector robot, the robotic arm follows a preset fixed program to finish box blanks absorbing, boxes shaping, and placing the boxes in the precise position.


Two side belts then drive the carton forward to seal the bottom.

These two belts are also driven by two servo motors to better ensure synchronous running, thus the fully-erected and bottom-sealer cartons are square enough.

Such robot box erector’s max. speed is up to 30CPM, and it works extremely stable, welcome you to contact us for more details.

Case Erector Glue

The working principle of case erector glue is the same as case erector tape, it could also one-stop finish picking and placing box blanks, erecting boxes, folding bottom flaps, and sealing the bottom, it uses the U.S. Nordson hot melt glue machine for the bottom sealing instead of pressure sensitive tape head.


Its sealing effect is beautiful & firm, and glue is more environmentally friendly than tape, which is currently a popular way of box bottom sealing.

Compared with tape sealing, hot melt adhesive seals the bottom more solidly, which could ensure that the sealing isn’t easy to loosen for long-distance transportation;

In addition, its anti-theft effect is better, etc.

Case Erector Tape

After the case erector folds the bottom flaps of the RSC case, then it sends the RSC case through the pressure sensitive tape applicator, which seals the bottom of the RSC case by applying the tape.


The only difference between it and the case erector glue is that the media used to seal the bottom is different.

Tape sealing is not as strong as hot melt glue sealing, if you package valuable items, we recommend you use hot melt glue for sealing.

But tape sealing has a benefit, the tape can carry your company’s promotional info, to promote your company and products for each shipment.


Best Case Erector

The best case erector should seamlessly connect the upstream and downstream equipment of your existing packaging line, needs less time for the carton size changeover, and is simple for operation and maintenance.

Before purchasing an RSC case erector, you’d better understand the following information, which will help you purchase the best case erector for you successfully.

  • Types of Case (RSC, HSC, or OSC)
  • Sizes of Cartons
  • Case Corrugating Quality
  • Erecting Speed Requirement
  • Sealing Types (Tape/Hot Melt Glue)
  • Automation Degree

Case Erector Price

The case erector price depends on its type, degree of automation, erecting speed, sealing media, etc.

Because of the differences in raw material and labor costs around the world, the box erector machine cost varies greatly from country to country.

A U.S. manufacturer lists the price for semi auto carton erector at $4,855.71/set.


The price for an auto case erector is $26,117.86/set.


Chinese manufacturers are definitely offering more attractive prices than this, you are welcome to contact us via email or WhatsApp below to get a quote for your comparison.
