Types of Folding Cartons

The material of folding cartons is 200-450gsm white paperboard, grey paperboard, kraft paper, 3-ply corrugated paper, etc.


White Paperboard

Regarding the production process of folding cartons, it has the following steps:

  • Die Line & Sheet Layout Design
  • Paperboard Sheeting & Printing
  • Post-press Finishing
  • Die-cutting
  • Folding & Gluing

Because its material is not hard enough, its bearing weight is relatively low, so it is suitable for packing light items.


When the folding carton is not filled with anything, it is a flat blank, which can save storage space.


As the most popular paper packaging box on the market, its common types include:

Straight Tuck End Box (STE)

As shown in the photo below, its top & bottom tuck flaps are on the same side.


It is visible in many industries, such as 3C, health & beauty, cosmetics, etc.

Reverse Tuck End Box (RTE)

The top & bottom tuck flaps of the reverse tuck end box are on the opposite side.


It is easy to assemble and ideal for packaging lightweight items.

Furthermore, one paperboard sheet converts more reverse tuck end boxes than straight tuck ones, thus each reverse tuck end box price is lower.

123 Bottom Box (Snap Lock Bottom)

Folding the snap lock bottom box includes 3 steps:


  • Female Bottom Closure Panel Folding
  • Two Closure Flaps Folding
  • Male Bottom Closure Panel Folding & Inserting


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

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

Auto Bottom Box (TTAB)

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


With glue tabs, its bottom base can bear more weight, thus it is also ideal for slightly heavy content packaging.

Due to pre-glued tabs, its price is higher than the tuck end & 123 bottom box.

Mailer/Postal/Pizza Box

A postal/mailer box is made of paperboard or corrugated paper and is popular in express packaging.


Thanks to its interlocking flaps, the mailer box assembly is easy, and tape is unneeded for closure.

Its double side panels make it more durable & resistant during transportation.

Burger Box

Burger box is also widespread all over the world with the development of fast food, its material is light cardboard, which effectively contains the burger, keeping the hamburger hot & fresh when it reaches consumers.


As the above photo shows, eight flaps must be glued to the side panels to form a burger box.

Lid & Base Box (Top & Bottom Box)

This type of box is produced from white or kraft paperboard, including a top lid and bottom base, and is suitable for packaging small gifts, toys, underwear, etc.

It adopts a continuous motion manner, whose speed can reach 40-60 CPM.


1 2 3 Bottom Box Erector

1 2 3 bottom box erector converts carton blanks to 1-2-3 bottom boxes.

When the closed carton comes out from the erector, its top closure panel & dust flaps are open for product filling.

Continuous Motion (40-60 CPM)

Continuous 123 bottom box erectors share the same design as the continuous tuck end box erectors mentioned above.

The only difference between them is their different carton folder & former unit.

As shown in the video above, a continuous 123 bottom box erector runs as follows:

A vacuum cup sucks a 123 bottom box blank from the magazine;


Secondly, the vacuum cup places the shaped box on the lug chain conveyor, the lug chain conveyor carries the 123 bottom box forward;


Thirdly, a tucker folds the bottom female closure panel;


Fourthly, two folders fold the bottom dust flaps of the 123 bottom box;


Fifthly, one holder holds the bottom dust flaps & female closure panel, the other holds the bottom male closure panel, then a tucker inserts the bottom male closure panel into the female closure panel.


Finally, the lug chain conveyor conveys the erected 123 bottom box to the outlet.

Two vacuum suction cups suck a box blank from the blank magazine and then convey the blank to the carton erecting unit.


  • Carton Erecting

A photoelectric eye detects the coming box blank and sends a signal to the PLC.


Then, the PLC sends a command to the other two vacuum suction cups to absorb the box blank, generating a reverse pulling force.

Two reverse pulling forces erect the box blank into a square shape.

  • Bottom Interlocking

Now it’s the bottom locking unit’s turn.


It folds the female bottom closure panel first, then folds the two dust flaps, and finally tucks the male bottom closure panel into the female bottom closure panel.


  • Closed Box Outputting

Compressed air blows the closed box out, and the closed boxes with open tops drop into the pre-placed collection container.

Cardboard Box Erectors

Cardboard box erectors transform corrugated carton blanks into fully erected, bottom-sealed boxes.


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

  • Regular Slotted Container (RSC)
  • Half Slotted Container (HSC)
  • Overlap Slotted Container (OSC)

Among them, RSC is the most common.


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.



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

Semi-automatic Carton Erector

Semi-automatic carton erectors require manual erecting of the carton blank, turning the blank into a rectangular shape with top & bottom mouths.


Rectangular Shape

Then, manually place the partially formed box into a pocket for bottom flaps folding.



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

Box Erector Robot

Programmable 4-8 CPM

A cobot case erector works slower than a conventional one, it can erect cartons of different sizes without downtime or changeovers.

If your cartons have a single size and high-speed requirements, choose the conventional type; if your carton size is various, choose the cobot.

Non-programmable 30 CPM

With servo motors driving, the robotic arm completes grabbing box blanks, and erecting boxes according to fixed programs.


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


With two servo motors drive ensures better synchronous belt running, thus the erected & bottom-sealed cartons are square enough.

Such a pre-programmed robotic box erector can erect 30 cases per minute, and it works extremely stable, contact us for more details.

Case Erector Glue

The case erector glue adopts a hot melt glue applicator for the bottom sealing instead of a pressure-sensitive tape head.


Its sealing effect is beautiful & firm, and glue is more environmentally friendly than tape, which is currently popular.

Compared with tape sealing, hot melt adhesive seals the bottom more solidly, ensuring the seal is not easy to loosen during long-distance transportation;

In addition, its anti-theft effect is better.

Case Erector Tape

A pressure-sensitive tape applicator seals the case bottom by applying the BOPP adhesive tape.


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

But tape sealing has a benefit, the tape can carry promotional info about your company, promoting your company with every shipment.


Best Case Erector

Best case erectors seamlessly connect to your existing packaging line, consume less time for carton size changeover, and are simple for operation & maintenance.

Digesting the following info will help you purchase a suitable case erector 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.

One U.S. manufacturer lists a semi-automatic cardboard erector at $4,855.71 per set.


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