Types of Folding Cartons

The folding carton‘s main material 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 in 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 heavier products, as its bottom base is really really sturdy.

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

  • 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 ideal for heavy content packaging.

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

The folding carton erectors’ main function is to erect, shape, square, 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.

  • Snap Lock Bottom Carton

The content below will introduce these 2 types of automatic carton erector one by one.

Tuck End Carton Erector

The tuck end carton 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, the tuck end carton erector is popular.


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 action 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 auto case erector machine.

These eyes monitor the actions 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 our eCommerce box carton erector’s workflow for 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 box below.


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

Snap Lock Bottom Carton Erecting Machine

With regard to the snap lock bottom carton erecting machine, it converts carton blanks to 1-2-3 bottom boxes.


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


As shown below:



SiroSilo 1-2-3 bottom box erecting machine 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, 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 our SiroSilo this packaging box erector’s workflow.

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