Carton (English or r): It is the most widely used packaging product, including corrugated cartons, single-layer cardboard boxes, etc., with various specifications and models according to different materials. Commonly used cartons have three layers, five layers and seven layers, which are less commonly used. Each layer is divided into lining paper, corrugated paper, core paper, surface paper. The surface paper includes tea board paper and kraft paper. Corrugated paper is used for the core paper. The color and feel of various papers vary. Likewise, 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 according to flute height. The mechanical properties of different corrugated board are also different. The larger type of corrugated cardboard has the highest plane pressure and the highest compressive strength. On the contrary, the plane pressure, vertical pressure, parallel pressure and buffering force of the corrugated cardboard type are better. The thickness type of corrugated cardboard is the largest, the second largest, and the third type is the smallest due to the small thickness of the cardboard. It is easier to process and bend, so 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 boxes are better, and double-sided corrugated boxes are better. Combined with a shape that is close to the outer surface, it can play an impact-resistant role. The combination of type or type can improve the physical and mechanical properties of the carton. From the printability point of view, both type and type are beneficial 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, when the length:width:height of cartons with the same volume is::, the most material-saving ratio is::, the most material-consuming ratio is::. Therefore, we 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 box volume in trucks and train carriages, and the stability of stacking during storage and transportation
