The main purpose than the corrugated packaging materials, but if the size of the carton deviation occurs, it is equal to committing a fatal mistake. Many in the industry will feel the carton size management control is essential, and it is the most simple, but as a user of corrugated boxes tend not to think so, the size of the problem will determine the value of the carton. Customers will accept the use of the right size.

Wrong size, no matter how well other projects, but also to no avail. But to really good management, control the size of the carton is a very good system of work. Thus, the simple things once against, is the most economical, most scientific management.

Size corrugated box designed to be the first dimension of the design. Because the size is relatively easy to determine, it is built of goods in kind or in-kind combination of measurement arrangement calculated to determine the outside dimensions. Emissions contents should try to save space and reasonable considerations supporting force. From the mechanical point of view, share part of the contents of the supporting force, then to carton compression index requirements can be reduced. Therefore, the mean decrease in cost and profit gains. If the contents are in boxes, cartons to consider the direction of silk thread, because good vertical silk thread silk thread than the lateral support force.

In the molding process in corrugated boxes, corrugated board to pressure line, so good bending corrugated board, while pressure line so that the destruction of the structure of corrugated board paper making in contraction, tissue extension. Its retractable many have a direct relationship with the cardboard thickness and pressure line approach. Thicker cardboard, the greater the value of stretching, the wider the line pressure, the greater the expansion and contraction values. But whether it is a two-wire, three-wire or five-wire crimping method of forming corrugated boxes, creasing wheel projection of the bottom line of corrugated board pressure areas will squeeze the center position of corrugated board. So, from the line and pressure line corrugated cardboard boxes inside size than when unfolded between the slightly shorter. This will make that part of the shortened size added as a correction value, the correction value is closely related to the thickness of the corrugated plate.

The most common carton in order to protect the contents, usually outside to shake butt cap sealing. This requires that the size of the carton roll cover must be calculated accurately, not only after docking there are gaps, we can not shake the cover overlay. In principle, the width of the roll cover manufacturing dimensions theoretical value should be wide box manufacturing half sizes. However, due to internal and external pressure on a rocking cover the same line, after the roll cover folded cover to produce the supporting role of foreign shake, shake outer cover is bound to have a certain gap in the docking place. Thus, calculated correction values outside the roll cover manufacturing dimensions of width is very important. This correction value is generally half the thickness of the cardboard pressure line, the pressure line but different devices which cause cardboard glossy paper, paper stretching is not the same, so it is best to be determined by actual measurement.

In simple terms, the structural design of corrugated boxes, corrugated cardboard should be determined based on the use of manufacturing equipment and the different production processes, and the use of different corrugation constituted, and the type and nature of the contents of the product, only mastered all The structural design of corrugated boxes, the size-related content, in order to manufacture products to protect and beautify corrugated boxes of goods.
