What is the three -layer carton?
Now that we are familiar with the concept of cardboard and flute, we can have a brief and complete introduction of three-layer cardboard. The cartons whose body consists of two layers of smooth cardboard and a flute layer in between are called three-layer cartons. Therefore, as the name suggests, this carton consists of three layers. is Due to its light weight and reasonable price, three-layer cardboard is the most widely used tool in packaging various products. Different layers are placed on top of each other with the help of glue, and finally a layer with relatively high strength is obtained. As a key point, note that three-layer cartons are designed and produced in standard sizes 1 to 9. The main difference between the types of three-layer cartons is the height and distance between the flutes.

What does a five -layer carton mean?
After introducing the three-layer cardboard, it is time to get acquainted with the five-layer cardboard. In order for people to be able to safely pack, move and store heavier and more sensitive objects using cardboard boxes, another type of carton has been designed and marketed under the title of five-layer carton. These cartons consist of two layers of flute and three layers of smooth cardboard. In such a way that the outer layers are made of liner and two flutes and another liner are placed between them. Due to the greater number of body layers, this cardboard shows more strength and resistance, and this has made it more popular. Also, 5-layer cartons are more resistant to humidity penetration and other environmental pollution due to the greater thickness of the body.
