What is the difference between ordinary cartons and load-bearing cartons

Ordinary carton: Generally speaking, it is a three-laminated carton, that is, a carton made of three layers of paper "outer surface paper, middle corrugated paper, and innermost cardboard paper", such as beer boxes, milk boxes, instant noodles 's box. The load bearing is relatively small.

Heavy-duty cartons: There are five-layer cartons, also known as five-laminated boxes, which are processed from five layers of paper: paper canister, corrugated paper, heart paper, corrugated paper, and boxboard paper. It is generally used in four-barrel packing boxes of edible oil and household appliances.

Generally, the corrugated layer adopts B corrugation for the outer layer and A corrugation for the inner layer. Compression and puncture resistance is greater than that of three-framed boxes. The seven-layer carton, also known as the seven-layered box, is processed from seven layers of paper: face paper, corrugated paper, heart paper, corrugated paper, heart paper, corrugated paper, and boxboard paper. It is generally rarely used on the market, and can be installed with some mechanical equipment and large household appliances. The combination of corrugated is generally interspersed by B and A. Compression resistance and puncture resistance are greater than the first two.

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

In terms of carton carrying, not only its structure, but also the thickness and strength of various papers used have a great influence on the carrying capacity of the carton.
