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.

　　紙箱的耐破性與抗壓性有什么直接關系?

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

　　抗壓性一般是指靜力，抗折力除靜力外還包括動力沖擊力。前者可以通過大疊加實驗確定，后者一般通過一定高度的自然落差和意外碰撞、運輸亂流來確定。

　　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.

　　瓦楞紙板瓦楞紙模型，根據(jù)瓦楞紙板的長度分為A、B、C、E四類，不同瓦楞紙板的機械性能不同。A型瓦楞紙板具有高的平面壓力和較高的抗壓強度，而B型瓦楞紙板則相反。型具有較好的平面壓力、垂直壓力、平行壓力和緩沖壓力。瓦楞紙板的厚度，A型、C型、B型再加，E型小，由于紙板厚度小，加工彎曲容易，因此，B型瓦楞紙板廣泛用于對紙箱抗壓強度要求較低的包裝箱。根據(jù)瓦楞紙板的不同機械性能，單面瓦楞紙板用A或C為好，雙瓦楞紙板用A、B或B, C型組合為宜，接近表面用B型，可起到抗沖擊作用。A、B或B、C組合，可提高紙箱的物理力學性能;從打印適宜性比較來看，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.

　　在保證紙箱質量的前提下，瓦楞紙箱應盡量節(jié)省加工材料和包裝成本。例如，對于相同體積的紙箱，使用長度:寬度:高度2:1:2，以節(jié)省多的材料，比例1:1:1的昂貴的材料。因此，方形方框應該盡量避免。產品與箱體的利用率，箱體與貨車、火車車廂的利用率，儲運、抽水過程中堆垛的穩(wěn)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.
