Carton (r or rr in English): It is the most widely used packaging product. Depending on the materials used, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. Commonly used cartons have three layers and five layers, and seven layers are less commonly used. Each layer is divided into lining paper, corrugated paper, core paper, and surface paper. The lining and surface paper include tea board paper and kraft paper. The core paper is corrugated paper. Various types of paper are used. The color and feel are different, and the paper (color, feel) produced by different manufacturers is also different. Corrugated cardboard is made of top paper, lining paper, core paper and corrugated paper processed into corrugated corrugated sheets through bonding. According to the needs of product packaging, corrugated cardboard can be processed into single-sided corrugated cardboard, three-layer corrugated cardboard, five-layer, seven-layer, eleven-layer and other corrugated cardboard. Principles for selecting corrugated boxes:
⑴Corrugated board corrugated board models
Corrugated board models are divided into four categories, B, and B according to flute height. The mechanical properties of different corrugated board are also different. Type B corrugated cardboard has the highest plane pressure and greater compressive strength, while Type B has the opposite effect. Type B has better plane pressure, vertical pressure, parallel pressure and buffering force. Thirdly, B-shaped corrugated paper has the smallest shape. Since it is easier to process and bend paperboard with a small thickness, B-shaped corrugated paper is widely used in packaging and shipping boxes that do not require high compressive strength. According to the different mechanical properties of corrugated board, single-sided corrugated paper It is better to use type or type for double-sided corrugated cartons. Type B or a combination of type B and type B is suitable for double-sided corrugated boxes. Type B is suitable for those close to the outer surface, which can resist impact. , Type B or a combination of Type B and Type B can improve the physical and mechanical properties of the carton. In terms of printability, Type B and Type B are both conducive to printing.
⑵ Box shape of corrugated carton
On the premise of ensuring the quality of the carton, the cost of carton processing materials and packaging should be saved as much as possible. For example, for cartons with the same volume, the length:width:height method saves the most materials, and the ratio method consumes the most materials. This should try to avoid using square boxes. We should also take into account the utilization rate of the box volume by the product, the utilization rate of the truck and train compartment volume by the box, and the stability of stacking during storage and transportation.
