Types of Folding Cartons
The material of folding cartons is 200-450gsm white paperboard, grey paperboard, kraft paper, 3-ply corrugated paper, etc.
Regarding the production process of folding cartons, it has the following steps:
- Die Line & Sheet Layout Design
- Paperboard Sheeting & Printing
- Post-press Finishing
- Folding & Gluing
Because its material is not hard enough, its 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 products.
The most common folding boxes on the market include the following types:
Straight Tuck End/Top (STE)
As shown in the photo below, the top tuck flap & bottom tuck flap of the straight tuck end box are on the same side.
It is one of the most popular cartons on the market, and it is visible in many industries, such as health & beauty, cosmetics, etc.
Reverse Tuck End/Top (RTE)
With reference to the following picture, you can notice that the top tuck flap & bottom tuck flap of the reverse tuck end box are on the opposite side.
It is ideal for packaging lightweight items, its assembly is easy.
As it keeps flat for storage & transportation, saves your warehousing and logistics fees.
Furthermore, 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.
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 sturdy.
Industries like health and beauty, toys, food, and pharmaceuticals 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.
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, the price of auto bottom cartons is higher than the tuck end boxes & 123 bottom boxes.
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 is easy to assemble and tape is unneeded for assembly and closure.
Its double side panels make it more durable and resistant during transportation.
What is a Folding Carton Erector?
The folding carton erectors erect, square & shape, and bottom-seal small 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 cartons are foldable.

Tuck End Box Erector
The tuck end box erector forms straight tuck cartons & reverse tuck cartons.
When these straight tuck & reverse tuck end boxes come out from the machine, their tops open outward for the follow-up product loading.
In lighting, electrical appliances, e-commerce, 3C, handicrafts, beauty, cosmetics, toys, food, and other industries, such a little carton erector is widely popular.
It has a compact footprint, moves flexibly for mobile use with casters, or works together with other packaging equipment to form a packaging line.
SiroSilo tuck end box erectors adopt mechanical linkage & pneumatic control, lower power & energy consumption, and cut your electricity bills every shift;
As PLC controls its operation, every motion is accurate, ensuring the carton forming quality.
You can set parameters on the touch screen, which is simple & convenient with English HMI.
The following video presents the English interface, please watch it for reference.
In addition, we installed several photoelectric eyes on this small box erector machine.
These eyes monitor the motions of various parts, such as detecting the carton status & miss, ensuring carton forming is smooth.
Tuck end carton forming includes the following steps:
- Carton Blank Pickup
- Bottom Dust Flap Folding
- Bottom Closing Panel Folding
- Bottom Tuck Flap Insertion
- Erected Carton Outputting
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.
If you have any more questions about this machine, you are welcome to send an email to email@example.com, we will reply to you within 1h from 5 a.m. to 9 p.m. Beijing time.
Auto Bottom Carton Erector
In 2021, SiroSilo customized an auto bottom caron erecting, loading, and sealing machine for a Canadian customer, packaging medical masks.
If you need an auto bottom carton erector, we just provide you with the carton erecting part in the video.
1 2 3 Bottom Box Erector
1 2 3 bottom box erector 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 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
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 falling process in the magazine, the falling contact area & friction force are small.
With the block-shaped strip guiding the carton blank falling, the falling process is smoother.
By adjusting the feed rod & lead screw, you can change the length & width of the blank magazine, thus the magazine can fit different carton sizes.
After the carton blank arrives at the carton forming station, the photoelectric eye detects it and feeds a signal to the PLC.
The PLC sends commands, and two vacuum suction cups absorb the upper part of the carton, applying an upward pulling force.
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 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.
You can better understand the workflow of 1 2 3 bottom box erector through the video below.
After bottom locking, the tucker will apply another force to the carton, and push the carton out.
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
Cardboard box erectors transform corrugated carton blanks into fully erected, bottom-sealed boxes.
It first picks and places the corrugated carton blanks, then erects these blanks into rectangular shapes with open tops and bottoms, and finally seals the bottom major (outer) and minor (inner) flaps for following product 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 connect to 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, folds the bottom flaps, seals the bottom, and then transports the completely erected and bottom-sealed case to the case packer.
Such an 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
Semi automatic carton erectors require manual erecting of the carton blank, turning the blank into a rectangular shape with top and bottom mouths.
Then, manually place the partially formed box into a pocket 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 is capable of erecting different sizes without downtime or changeover.
Pairing with multiple carton blank magazines, this robotic case erector introduces an industrial vision system to identify cartons of different sizes.
If your carton size is single and the speed requirement is high, then choose the conventional type; if your carton size is various, then choose the robot.
Fixed Program 30 CPM
With three servo motors driving, the mechanical arm follows a preset fixed program to finish box blank grabbing, box shaping, and box placing in precise positions.
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-sealed cartons are square enough.
Such a robot box erector is capable of erecting 30 cases per minute, and it works extremely stable, welcome you to contact us for more details.
Case Erector Glue
The case erector glue completes the one-stop picking & placing box blanks, erecting boxes, folding bottom flaps, and sealing the bottom, it uses the U.S. Nordson hot melt glue applicator 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 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
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 case bottom by applying the BOPP adhesive tape.
The only difference between it and the case erector glue is the bottom sealing media.
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 the promotional inf of your company, promoting your company & products with every shipment.
In recent years, water activated tape has gradually become popular.
We can also provide water activated tape case erector sealer, but its speed is only 1-4 CPM, please consider whether this speed is acceptable to you before consulting us.
