What is the Difference between Ordinary Carton and Heavy-duty Carton Design?

　　Ordinary carton: Generally speaking, it is a three-layer carton, that is, a carton made of three layers of paper, such as beer boxes, milk boxes and instant noodle boxes. The weight-bearing is relatively small, and the corrugated paper is usually B flute or E flute.

　　Heavy carton: There are five layers of cartons, also known as five laminated boxes "by the face paper, corrugated paper, heart paper, corrugated paper, box board paper" five layers of paper processing and made. It is generally used for four-barrel boxes of edible oil and household appliances, such as TVs, washing machines, etc.

　　Corrugated paper is generally made of B flute for the outer layer and A flute for the inner layer. The compression and puncture resistance is greater than that of three-layer cartons. Seven-layer carton, also called seven-layered box, is made of seven layers of paper: face paper, corrugated paper, heart paper, corrugated paper, heart paper, corrugated paper and boxboard. It can be used for machinery, equipment and large household appliances. The combination of corrugated board is generally composed of B flute and A flute interleaved. The compression and puncture resistance is greater than the first two.

　　Honeycomb carton: This carton breaks the traditional form of the corrugated carton, the outside and inside is boxboard paper in the middle is made into a honeycomb This carton is mostly used for the transportation of machinery and equipment, the pressure resistance is very high.

　　In terms of carton load-bearing not only depends on its structure, the thickness and strength of the various papers used have a great impact on the load-bearing of the carton.
