Penetration strength refers to the maximum power that the carton can withstand sudden impact; fracture strength refers to the internal resistance to local extrusion; the domestic light industry standard has cancelled the puncture strength index, but the export carton still has requirements.

　　纸箱的耐破性与抗压性有什么直接关系?

　　What is the direct relationship between the bursting resistance and compression resistance of cartons?

　　抗压性一般是指静力，抗折力除静力外还包括动力冲击力。前者可以通过大叠加实验确定，后者一般通过一定高度的自然落差和意外碰撞、运输乱流来确定。

　　Compression resistance generally refers to static force, bending force includes dynamic impact force in addition to static force. The former can be determined by the maximum superposition experiment, while the latter is generally determined by a certain height of natural drop and accidental collision and transport turbulence.

　　瓦楞纸板瓦楞纸模型，根据瓦楞纸板的长度分为A、B、C、E四类，不同瓦楞纸板的机械性能不同。A型瓦楞纸板具有高的平面压力和较高的抗压强度，而B型瓦楞纸板则相反。型具有较好的平面压力、垂直压力、平行压力和缓冲压力。瓦楞纸板的厚度，A型、C型、B型再加，E型小，由于纸板厚度小，加工弯曲容易，因此，B型瓦楞纸板广泛用于对纸箱抗压强度要求较低的包装箱。根据瓦楞纸板的不同机械性能，单面瓦楞纸板用A或C为好，双瓦楞纸板用A、B或B, C型组合为宜，接近表面用B型，可起到抗冲击作用。A、B或B、C组合，可提高纸箱的物理力学性能;从打印适宜性比较来看，B型和C型有利于打印。、

　　According to the length of corrugated board, it can be divided into four categories: A, B, C and e. the mechanical properties of different corrugated boards are different. Type a corrugated board has the highest plane pressure and higher compressive strength, while type B corrugated board has the opposite. Type A has better plane pressure, vertical pressure, parallel pressure and buffer pressure. The thickness of corrugated board, A-type, C-type and B-type plus, E-type is the smallest. Because the thickness of the board is small and it is easy to process and bend, B-type corrugated board is widely used in packaging boxes with low compressive strength requirements for cartons. According to the different mechanical properties of corrugated board, single-sided corrugated board with a or C is better, double corrugated board with a, B or B, C type combination is appropriate, close to the surface with B type, can play an impact resistance role. The combination of a, B or B, C can improve the physical and mechanical properties of cartons; from the comparison of printing suitability, type B and C are conducive to printing.

　　在保证纸箱质量的前提下，瓦楞纸箱应尽量节省加工材料和包装成本。例如，对于相同体积的纸箱，使用长度:宽度:高度2:1:2，以节省多的材料，比例1:1:1的昂贵的材料。因此，方形方框应该尽量避免。产品与箱体的利用率，箱体与货车、火车车厢的利用率，储运、抽水过程中堆垛的稳定性。

　　On the premise of ensuring the quality of cartons, corrugated cartons should try to save processing materials and packaging costs. For example, for cartons of the same volume, use length: width: height 2:1:2 to save the most material, the most expensive material with a ratio of 1:1:1. Therefore, square boxes should be avoided as much as possible. Utilization ratio of products and boxes, utilization ratio of boxes and freight cars, and stability of stacking during storage, transportation and pumping.
