Corrugated boxes manufacturing process

Cardboard boxes are industrially prefabricated boxes, primarily used for packaging goods and materials and can also be recycled. Specialists in industry seldom use the term cardboard because it does not denote a specific material. When the cardboard box is shaped into a series of parallel ridges and grooves so as to give added rigidity and strength, then it is called a Corrugated box.

The manufacturing of Corrugated boxes involves following steps:

Step 1.

The Raw material for making the Corrugated box is made of brown Kraft paper. The first step of this process is passing the Kraft papers through Corrugator or Corrugation machine. Corrugation machine attaches 2 layers of paper and corrugate it, and auto cutter cuts it according to the size required.

Step 2.

After Corrugator, the paper passes through Pasting machine, the sheets are pasted in this machine to make it thick and strong. The strength of the corrugated box can be divided in categories – three ply, five ply, seven ply etc. Depending upon the type of products used and the kind of handling required- the ply value of the boxes can vary. For example, a three ply box will have one fluted paper sandwiched between two line boards. This kind of box can be used in shipping and storing products that are not heavy and not delicate. Similarly, five ply boxes will have three linerboards and two fluted papers sandwiched together.

Step 3

The next step after Pasting machine is passing the paper through Creasing machine, sheets are creased in this machine according to size.

Step 4

After Creasing machine, Paper passes to Slotting machine, it slots or cuts the part of sheets so that the original shape of the box is ready (i.e. the size of box that is required by one)

Step 5

Finally, the sheet is passed through Stitching machine, it is the last process and stitches the sheets to make the box as per requirement

Finally, the boxes are ready

One more Process can be added depending on the requirement of the customer. i.e. Printing of the customer’s symbol or logo on the paper
