1. Reasonably designed carton size

在设计纸箱时，除了考虑如何在一定的容积下用料更省，还应考虑市场流通环节对单个纸箱的尺寸及重量的限制，销售习惯，人体工程学原理及商品内部排列的方便性与合理性等。根据人体工程学原理，合适的纸箱外形尺寸，不会导致人体的作业疲劳及损伤。过重的纸箱包装，运输效率会受影响，损坏概率增加。按贸易惯例，一包装纸箱重量限制为20kg。实际销售中，对同一种商品，不同的包装方式在市场上的程度是不同的。因此设计纸箱时，应尽量按销售习惯来确定包装的大小。

When designing cartons, in addition to considering how to save materials under a certain volume, we should also consider the restrictions of the market circulation on the size and weight of a single carton, sales habits, ergonomic principles and the convenience and rationality of the internal arrangement of goods. According to the principle of ergonomics, the appropriate overall dimension of the carton will not lead to the operation fatigue and damage of the human body. If the cartons are too heavy, the transportation efficiency will be affected and the damage probability will increase. According to international trade practice, the weight of one carton is limited to 20kg. In actual sales, for the same commodity, different packaging methods have different popularity in the market. Therefore, when designing cartons, we should try to determine the size of packaging according to sales habits.

所以在纸箱设计过程中，应综合考虑各种因素，在不提高成本，不影响其包装功效的前提下，提高纸箱的抗压强度。并在充分了解内装物的特性后，确定好纸箱的合理尺寸。

Therefore, in the process of carton design, various factors should be comprehensively considered to improve the compressive strength of the carton without increasing the cost and affecting its packaging efficiency. After fully understanding the characteristics of the contents, determine the reasonable size of the carton.

2. 瓦楞纸板达到规定的厚度

2. The corrugated board reaches the specified thickness

瓦楞纸板的厚度对纸箱的抗压强度影响很大。在生产过程中，瓦楞辊磨损严重，造成瓦楞纸板的厚度下降，纸箱的抗压强度也随之下降，导致纸箱的破损率增加。

The thickness of corrugated board has a great influence on the compressive strength of carton. In the production process, the corrugating roller is seriously worn, resulting in the decrease of the thickness of the corrugated board and the compressive strength of the carton, resulting in the increase of the damage rate of the carton.

3. 减少瓦楞的变形

3. Reduce the deformation of corrugated

，要控制好原纸的质量，特别是瓦楞芯纸的环压强度、水分等物理指标。其次，对瓦楞纸板工艺进行研究，改变因瓦楞辊的磨损、瓦楞辊间的压力不足等因素导致的瓦楞变形。第三，改进纸箱制造工艺，调整制箱机的送纸辊的间隙，以及将纸箱印刷改成柔性版印刷为主，以减少瓦楞的变形。同时也要注意纸箱的运输，尽量采用厢体车运输纸箱，减少因油布、绳子的捆扎和装卸工的踩踏而引起瓦楞变形。

First of all, we should control the quality of base paper, especially the physical indexes such as ring compression strength and moisture of corrugated core paper. Secondly, the corrugated board process is studied to change the corrugation deformation caused by the wear of corrugating rollers and the insufficient pressure between corrugating rollers. Third, improve the carton manufacturing process, adjust the gap of the paper feeding roller of the carton making machine, and change the carton printing to flexographic printing, so as to reduce the deformation of corrugated. At the same time, we should also pay attention to the transportation of cartons, and try to use box cars to transport cartons, so as to reduce the corrugated deformation caused by the binding of tarpaulins and ropes and the trampling of stevedores.

4. 设计合适的瓦楞纸板层数

4. Design appropriate layers of corrugated board

瓦楞纸板按其材料的层数可分单层、三层、五层、七层。随着层数的增加，具有较高的抗压强度和堆码强度。因此，可根据商品的特征、环境参数及消费者要求进行选择。

Corrugated board can be divided into single layer, three layers, five layers and seven layers according to the number of layers of its material. With the increase of the number of layers, it has high compressive strength and stacking strength. Therefore, it can be selected according to the characteristics of goods, environmental parameters and consumer requirements.

5. 加强对瓦楞纸箱剥离强度的控制

5. Strengthen the control of the peeling strength of corrugated boxes

纸箱的瓦楞芯纸与面纸或里纸的粘合强度可通过检测仪器来控制。如果剥离强度达不到标准要求，要寻找原因。要求供应商加强对纸箱原材料的检验，纸张的紧度、含水率指标一定要有关标准。并通过提高粘合剂质量、改进设备等来达到国标要求的剥离强度。

The adhesive strength between corrugated core paper and face paper or inner paper of carton can be controlled by testing instrument. If the peel strength does not meet the standard requirements, find the reason. The supplier is required to strengthen the inspection of carton raw materials, and the tightness and moisture content of the paper must meet the relevant national standards. The peel strength required by the national standard is achieved by improving the quality of adhesive and equipment.

6. 合理设计纸箱图案

6. Reasonably design carton pattern

纸箱应尽量避免满版印刷，以及横向带状印刷，特别是箱面中横向印刷，因为它的作用和横压线一样，印刷压力会将瓦楞压溃。在纸箱的箱面印刷设，要尽量减少套色次数。一般单色印刷后，纸箱抗压强度降6%—12%，而三色套色后将降17%—20%。

The carton should avoid full page printing and horizontal strip printing as far as possible, especially the horizontal printing in the carton surface, because its function is the same as the horizontal pressing line, and the printing pressure will crush the corrugated. In the printing design of carton surface, the number of color registration should be reduced as much as possible. Generally, the compressive strength of cartons will be reduced by 6% - 12% after monochrome printing, and 17% - 20% after trichrome printing.

7. 确定合适的用纸规定

7. Determine the appropriate paper regulations

在具体的纸箱用纸设计过程中，应适当选取合适的原纸，原材料的质量好坏是决定瓦楞纸箱抗压强度的主要因素。通常，瓦楞纸箱的抗压强度与原纸的定量、紧度、挺度、横向环压强度等指标成正比；与含水率成反比。另外，原纸的外观质量对纸箱抗压强度的影响也不容忽视。

In the specific carton paper design process, appropriate base paper should be selected appropriately. The quality of raw materials is the main factor determining the compressive strength of corrugated boxes. Generally, the compressive strength of corrugated box is directly proportional to the quantitative, tightness, stiffness, transverse ring compression strength and other indicators of base paper; Inversely proportional to water content. In addition, the influence of the appearance quality of base paper on the compressive strength of carton can not be ignored.

因此，要保证足够的抗压强度，需要选择品质优良的原材料。但在设计纸箱的用纸时，不要一味地提高纸张的克重与等级，增加纸板总克重。实际上瓦楞纸箱的抗压强度取决于面纸和瓦楞芯纸的环压强度的组合效果。而瓦楞芯纸对强度的影响更大，所以不管从强度上还是从经济性考虑，提高瓦楞芯纸等级性能的效果要优于提高面纸等级，而且经济得多。可通过到供应商实地去检查，并抽取原纸样品，测出原纸的一系列指标来控制好纸箱的用纸，防止偷工减料，以次充好。

Therefore, to ensure sufficient compressive strength, we first need to select high-quality raw materials. However, when designing the paper for carton, don't blindly improve the gram weight and grade of paper and increase the total gram weight of paperboard. In fact, the compressive strength of corrugated box depends on the combined effect of the ring compressive strength of face paper and corrugated core paper. The corrugated core paper has a greater impact on the strength, so regardless of the strength or economy, the effect of improving the grade performance of corrugated core paper is better than that of facial paper, and it is much more economical. We can control the use of paper in cartons by going to the supplier for on-site inspection, taking base paper samples and measuring a series of indicators of base paper, so as to prevent Jerry built and shoddy.

8. 改进运输

8. Improve transportation

减少商品运输搬运的次数，采用就近发货的方法，改进搬运方式(建议采用铲板搬运)；对搬运工等进行教育，提高其质量意识，杜绝野蛮装卸；在装车运输时注意防雨防湿，捆绑不能过紧等。

Reduce the times of commodity transportation and handling, adopt the method of nearby delivery, and improve the handling method (shovel handling is recommended); Educate the porters, improve their quality awareness and eliminate rough loading and unloading; Pay attention to rain and moisture protection during loading and transportation, and the binding shall not be too tight.

9. 加强对经销商仓库的管理

9. Strengthen the management of dealers' warehouses

对销售的商品应遵循先出的原则，堆码的层数不能太高，仓库不能过于潮湿，应保持干燥通风。

The principle of first in first out shall be followed for the goods sold. The number of layers of stacking shall not be too high, and the warehouse shall not be too wet. It shall be kept dry and ventilated.
