Forms of cartons

Cartons commonly used three-layer, five-layer, or seven-layer. Each layer is divided into lining paper, corrugated paper, core paper, face paper, lining, face paper, tea board paper, kraft paper, and core paper with corrugated paper. A variety of paper colors and feel are different. Carton boxes are generally divided into A-type, B-type, and C-type, packaging cartons and beer boxes, knife cards, and partitions. A-type is called common A1, and the general standard type A3 has a bottom without cover or cover without bottom type. A5 has a double cover completely interspersed. Partition refers to the cardboard that protects the objects on the top, middle, bottom, left and right of the carton from each other.

Wrap-around carton flute direction parallel to the length of the cardboard, attached to the side of the box. In use, the die-cut carton blanks are handed over to the packaging user, who then packs the product using an automatic wrapping machine. Separate cartons, in the circulation process, can be divided into two or more to solve the contradiction between mass production and small-volume sales. A separate carton is based on the traditional standard box type, using a variety of auxiliary materials to the small box type to be combined and become. Triangular column type corrugated carton is box body and corner liner one-page molding. A corrugated carton has four corners of the formation of a triangular column or right-angle column structure so as to improve the compressive strength of twenty to fifty percent.

How to distinguish between good and bad cartons

The quality of cartons can be identified from the large cardboard boxes width and height. The weight of the paper is the most fundamental. Then, look at the surface of the carton gloss because the cowhide belongs to the rough paper. The production process on the surface of the gloss requirements is low, but the requirements of the flat point can be seen in the core paper. The core paper can only be done in the middle of the wave and the reason for the intermediate partitions. Hardness and thickness is also important parameter of paper quality, high hardness is not necessarily thick, and thick is not necessarily high hardness.
