How to produce cartons in carton making with a variety of quality raw materials is one of the important issues that carton makers and even customers can achieve positive results by being aware of it. For example, carton makers can achieve high quality products by complying with the necessary standards. On the other hand, with the knowledge they gain, customers can place their orders in the best carton companies. If you are aware of the standard work procedure, you can easily distinguish quality cardboard from low-quality and make a smart choice.
Steps
The first step: In the first step, it is necessary to prepare the raw materials needed to make all kinds of cardboard sheets. At first, tree trunks or cardboard waste are used to produce paper pulp. There is a huge amount of industrial equipment that pulps wood chips or recycled cardboard to prepare them for the production of paper or cardboard sheets. Paper pulp will be produced during a series of physical and chemical steps.
The second step: In the next step, the paper pulp is converted into paper and cardboard in special machines. The most important difference between paper and cardboard is their thickness. For this reason, cardboards are used as different layers of a cardboard sheet (i.e. liner and flute) due to their high thickness. The width of the cardboards is not the same and is different. So that their width is usually in the range of 90 to 250 cm and their length is produced based on customer orders.
The third stage: After the layered cardboard production stage, they are ready to be used in the production process of all kinds of cardboard and cardboard boxes. At this stage, it is the turn to cut the cardboard, which uses two methods of line and chuck and die cut. The line and groove method is less delicate and accurate than diecut cutting and is used in the production of flexo cardboard.
Diecut cutting, which is made by a special diecut mold, is mostly used to produce laminated cardboard. The speed of this type of cutting (i.e. die cut) is very high, so that it is possible to produce about 10,000 cartons in 10-8 hours per day. This method is the best option for producing cartons in high volumes.
Fourth step: In general, there are many printing methods, each of which has its own application, and one of them is chosen depending on the needs and tastes of the customer. For example, cardboard boxes with flexo printing have designs and colors, but these designs and colors do not have good transparency and are simply and directly inserted on the cardboard. Also, flexo carton is not used much in the export industry. While offset printing, which can be followed by the laminated carton process, plays an important role in export.
Final stage: In the final stage, the glue machine is used to glue the edges of the carton together. In this way, the edges of the cardboard are glued together with a thin layer of glue to take the shape of a cardboard box. In addition to glue, special staples can also be used to connect the edges of the carton.
Introduction to the types of cardboard cartons and their characteristics
There are three main types of corrugated cardboard used to make cartons:
Single layer: One layer of fluted board is placed between two sheets of lining board. This makes a single wall cardboard carton.
Double layer: Two layers of flute glued to three layers of lining board. This creates a double-walled cardboard carton that is stronger than single-walled mailing cartons.
Three-layer: Three layers of floating are laminated with four lining boards. This makes the three-wall or three-layer carton the heaviest and most durable among postal cartons.

What is the postcards?
All types of postal cartons are made of cardboard. Cardboard is a type of hard paper that is made of multiple layers of paper, and between these layers, there are layers of sticky material (glue) that stick the cardboard together and make it strong and resistant. Usually, in the production of postal cartons, double cardboards, double cardboard boards and more resistant cardboards are used. These types of cardboards are suitable for transporting heavier and more sensitive items by improving the strength and strength of postal cartons.
Cardboards are usually made from wood fibers such as shredded paper. Using chemical and mechanical processes, these fibers are turned into fine sand and turned into pulp. Then, the pulp goes in the form of neat and thinned sheets on the flattened strips and becomes cardboard sheets by drying. These sheets are then cut and glued together using a suitable glue to form the structure of the postal carton.
