New classification standards for paper packaging industry

[China Packaging Network News] According to different paper, corrugated cardboard boxes, single-layer cardboard boxes and so on. There are three layers and five layers commonly used in cartons. Seven layers are used less. Each layer is divided into paper, corrugated paper, core paper, and surface paper. There are teaboard paper, kraft paper, corrugated paper for core paper, and the color of various papers. The hand feel is different, and the paper (color, feel) produced by different manufacturers is not the same. Different corrugated corrugated shapes and bonded corrugated cardboard have different functions. Even with the same quality of facial and liner paper, due to the difference in shape, there is a difference in the performance of the corrugated cardboard. Their technical specifications and requirements are shown in Table 1. The corrugated cardboard made of A-type crucibles has good cushioning properties and is full of certain elasticity. C-type crucibles are inferior to A-type crucibles. But the stiffness and impact resistance are better than that of the A-type crucible; the arrangement density of the B-type crucible is large, the surface of the corrugated paperboard made is smooth, the bearing pressure is high, and it is suitable for printing; the E-type crucible is thin and dense, and it also shows that it is in production. In the manufacture of corrugated cartons, it is common to distinguish cartons by box type.

The box-type structure of corrugated boxes is commonly used internationally by the international carton box standards developed jointly by the European Federation of Corrugated Box Manufacturers (FEFCO) and the Swiss Board Association (ASSCO). This standard is approved internationally by the International Corrugated Board Association. According to the international carton box type standard, the carton structure can be divided into two basic types and combination types.

The basic type is the basic box type. There are legends in the standard, which are generally represented by four digits. The first two indicate the type of box and the last two indicate the different types of boxes in the same box type. For example, 02 indicates a slotted carton; 03 indicates a slip-on carton. The combination type is a combination of basic types, that is, composed of two or more basic boxes, represented by multiple sets of four digits or codes. For example, the upper flap of a carton can be type 0204 and the lower flap is type 0215.

With the popularity of fine goods, more and more cardboard boxes are on the whiteboard. The industry is more and more closely related to printing. At the same time, it also promotes the development of computer graphic design.

China's national standard GB6543-86 refers to the international box-type standard series that specifies the basic box type for single corrugated cardboard boxes and double corrugated cardboard boxes for transport packaging.

However, in the late 1980s, with the changes in the distribution channels and market sales forms, a number of non-standard corrugated boxes with novel structures emerged, and, with the birth of each new structure, there is almost a set of Corresponding to the advent of fully automatic packaging systems or packaging equipment, it greatly enriches the application of cartons.
