Kunshan carton is mainly used for product packaging, which can protect the product well, the packaging is beautiful, which is conducive to the handling transportation of the product, but it will damage the product, at the same time can well enhance the value of the product level.

　　Introduction to Carton

　According to the type of corrugated board, the internationally popular types of corrugated board are divided into A, B, C, E. The main difference is that the shape of the corrugated board is different, so the performance characteristics of the bonded corrugated board are also different. The same face paper lining paper have significant differences due to the difference in flute shape: the cushion made of corrugated cardboard is good, with a certain degree of elasticity, the B-shaped groove has high column density, the surface of corrugated cardboard is flat, the bearing pressure is high, which is suitable Printing; Type C flute is as good as Type A flute. But the impact resistance is better than the a-type coil; the E-type groove is thin dense, showing its strength.

　　Carton Size

　　Corrugated paper is compressed into rigid corrugated cardboard by various kinds of kraft paper. Our ordinary corrugated cardboard is mainly divided into three-layer corrugated cardboard, five-layer corrugated cardboard, seven-layer corrugated cardboard. For three-layer corrugated paper, the basic weight is about 8 kg, that is, about 4 kg. If the weight of the goods reaches 5 kg, choose 5-layer corrugated paper, so that the box is easy to handle it is easy to break.

　　Principles of buying corrugated boxes

　　When choosing a corrugated carton, the nature, weight, storage transportation conditions circulation environment of the product should be taken into account. Second, it should be based on the design principles of anti-impact packaging the design method of corrugated carton. In addition to relevant standards, the packaging of export commodities is based on international standards. required by foreign countries passed relevant tests, so the corrugated box packaging should pay attention to these two points in general selection.

　　(1) Corrugated model of corrugated cardboard

　　The types of corrugated cardboard are divided into four categories: A, B, C, E according to the length. The mechanical properties of different corrugated cardboard are also different. Type A corrugated board has high plane pressure higher compressive strength, while type B is the opposite. Type C is good for plane pressure, vertical pressure, parallel pressure buffer pressure; the thickness of corrugated board, A max, C seconds, B E are the smallest. Because the thickness of cardboard is small, it is easier to bend. Therefore, type B corrugated paper is widely used in packaging boxes that require low compressive strength.

According to the different mechanical properties of the corrugated cardboard produced by the Kunshan corrugated cardboard box manufacturer, the single-sided corrugated cardboard box is preferably type A C, the double-sided corrugated cardboard box is appropriately combined with type A, B B C, which is close to the surface of type B. Play a certain impact. A B, the combination of B C improves the physical mechanical properties of the carton; the comparison of print suitability, B C are good for printing.

　⑵The box shape of the tile carton

　On the premise of ensuring the quality of cartons, try to save processing materials packaging costs. For example, for a carton of the same volume, when the length:width:height is 2:1:2, the material is most saved, the ratio is 1:1:1. Therefore, the plaza should try to avoid stacking stability when considering the utilization rate of the product to the box body, the utilization rate of the box to the truck, the capacity of the railway carriage, the capacity of storage, transportation pumping.

　　What is the direct relationship between the damage resistance of the carton the pressure resistance

The compressive force of a carton generally refers to static pressure, which includes dynamic impact in addition to static pressure. The former can be determined by max stacking experiments, the latter is generally determined by a certain height of natural drop, accidental collision, transportation turbulence.

　　 What is the conceptual difference between the compressive strength compressive strength of a carton

　　Penetration strength refers to the max power that the carton can withstand sudden impact; the breaking strength refers to the internal resistance to local squeezing energy; the current domestic light industry standard has cancelled the penetration strength index, but there are still requirements for export cartons.
