What is the difference between ordinary carton and heavy duty packaging carton design:

Ordinary carton: generally speaking is a three-laminated box, that is, by the three layers of paper "outside the face of the paper, the middle of the corrugated paper, and the innermost layer of the boxboard paper" processed from the carton, like beer boxes, milk boxes, instant noodles boxes. Relatively small load-bearing, corrugated paper are generally used B flute or E flute heavy-duty cartons: there are five-layer cartons, also known as five-mounted box "by the surface paper, corrugated paper, heart paper, corrugated paper, boxboard" five layers of paper processing and become. Generally used in edible oil four barrels packing boxes and household appliances. The corrugated board is generally made of B flute for the outer layer and A flute for the inner layer. Pressure and puncture resistance is greater than the three-layer box. Seven-layer carton, also known as seven-mounted box "by the face of the paper, corrugated paper, corrugated paper, heart paper, corrugated paper, heart paper, corrugated paper, boxboard" seven layers of paper processing and become. Generally rarely used on the market, can be loaded with some mechanical equipment, and large household appliances. The combination of corrugated board is generally interspersed with B flute and A flute. Pressure and puncture resistance is greater than the first two. Honeycomb carton: this carton breaks the traditional form of corrugated carton, outside and inside the middle of the box board is made into honeycomb this carton is used for the transportation of machinery and equipment, pressure resistance is very high. In the carton bearing not only look at its structure, the thickness and strength of the various paper used in the carton bearing impact is also very large.
