Pizza Box Folding Machine

A pizza box folding machine converts box blanks into sealed-bottom, open-top mailer/postal, lid & base, and pizza boxes for following product loading.


The photo above shows a standard mailer/postal box, it is made of kraft cardboard or corrugated paper and is popular in express packaging.


A pizza box’s structure may be the same as a mailer box, or there may be some minor differences.


The standard lid & base box are very simple, including a top lid and bottom base, as shown in the figure below:

Pizza Box Folding Machine Choice

In the Chinese market, almost all manufacturers produce mailer box folding machines, or lid &  base box forming machines.

Namely, if your pizza box doesn’t share the same design as the mailer box, you should discuss customization possibilities with these mailer box former manufacturers.

After confirming the customization possibility, you must clarify your requirements from the following aspects.

Box Sizes

After you communicate all your box sizes to the manufacturer, they will recommend the most suitable model and try their best to ensure that all your boxes are foldable on one machine.


Lock Panel Qty.

For pizza boxes, usually, only the front panel needs to be locked;


For postal/mailer boxes, some boxes need to lock the left & right side panels, and some boxes need to lock the left & right side panels plus the front panel.


Because the lock panel quantity is different, the machine price varies.


If your requirements for output are not high, we suggest you choose a moderate-speed machine, 700-1200 boxes per hour.

Such a machine has good stability, a long service life, and brings sustainable benefits.


If your output is high, and your budget is sufficient, you can buy an automatic pizza box folding machine with a higher configuration, further improving efficiency.

However, high-speed machines place a huge burden on power units, and their structure is more complex, with extremely high requirements for operators.

Therefore, you must hire high-level operators at a high price to avoid a failure rate increase.

Customized Components

Some customers will specify the brand of components (such as PLC, inverter, touch screen, air cylinder, etc.).


These requirements are achievable, but the price will be higher than the standard.

In addition to the high price of branded components, manufacturers have to rewrite software codes for different brands, which consumes more manpower & time.

Optional Hot Melt Glue Applicator

Some mail/postal boxes require hot melt glue to seal the side panels.

In this case, you must use a hot melt glue applicator.

If you choose Robatech or Nordson hot melt adhesive applicators, they are expensive and have good effects;


Chinese hot melt glue applicators are cheaper, and the effect is not as good as Robatech or Nordson.
