Today, the need to package and transport goods needs to ensure safety and durability. 5-layer carton boxes not only meet the above requirements but also bring many notable advantages. Let’s explore in this article.
The definition of 5-layer carton box
As the name suggests, this is a type of carton with 5 layers, including 2 layers of corrugated paper and 3 layers of flat paper. The paper and corrugated are arranged alternately to create a sturdy, impact-resistant carton structure.
Besides, 5 ply carton boxes are often used to package and transport large products weighing over 15kg, such as furniture, exteriors, refrigeration equipment, and electronics.
Structure and uses of 5 ply corrugated box
Typically, a 5-layer carton will have the following composition:
- The surface layer is the outermost part of the box, which directly contact with external influences. On this side, a layer of beautiful and smooth paper will be used for printing or coating.
- The middle layer will have a structure of 1 corrugated – 1 paper – 1 corrugated. Typically, 5 ply carton boxes use a double corrugated structure to optimize strength, such as BC flute, BE flute, EE, or EF flute.
- The inside layer is similar to the surface and will be a flat layer of paper. In addition, the inside can be coated with a water-resistant layer or wax if it is a carton packed with frozen goods.
Each layer is important and has its own use, complementing each other to create a complete five-layer carton.
