There are three basic types of cartons, including roll-type cartons, separate-type cartons and triangular column-type cartons, the following is a brief introduction to the design features of the carton by a professional carton manufacturer: The box joint of the wrapped corrugated carton is connected to the side of the carton, and its cord is parallel to the cardboard, its main feature is material saving. The big characteristic of separated carton is that it can be separated into two parts, which solves the contradiction of large and small batch production and packaging to some extent, and its packing has high compressive strength, so it is a kind of carton which is convenient to use. The Triangle column box is the only box which is connected with the corner liner to form a page. Its four corners form the triangle column structure, which makes the compression strength of the box have a greater improvement.
