1. Reasonably designed carton size

在設(shè)計(jì)紙箱時(shí)，除了考慮如何在一定的容積下用料更節(jié)省，還應(yīng)考慮市場(chǎng)流通環(huán)節(jié)對(duì)單個(gè)紙箱的尺寸及重量的限制，銷售習(xí)慣，人體工程學(xué)原理及商品內(nèi)部排列的方便性與合理性等。根據(jù)人體工程學(xué)原理，合適的紙箱外形尺寸，不會(huì)導(dǎo)致人體的作業(yè)疲勞及損傷。過(guò)重的紙箱包裝，運(yùn)輸效率會(huì)受影響，損壞概率增加。按貿(mào)易慣例，一包裝紙箱重量限制為20kg。實(shí)際銷售中，對(duì)同一種商品，不同的包裝方式在市場(chǎng)上的受歡迎程度是不同的。因此設(shè)計(jì)紙箱時(shí)，應(yīng)盡量按銷售習(xí)慣來(lái)確定包裝的大小。

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.

所以在紙箱設(shè)計(jì)過(guò)程中，應(yīng)綜合考慮各種因素，在不提高成本，不影響其包裝功效的前提下，提高紙箱的抗壓強(qiáng)度。并在充分了解內(nèi)裝物的特性后，確定好紙箱的合理尺寸。

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. 瓦楞紙板達(dá)到規(guī)定的厚度

2. The corrugated board reaches the specified thickness

瓦楞紙板的厚度對(duì)紙箱的抗壓強(qiáng)度影響很大。在生產(chǎn)過(guò)程中，瓦楞輥磨損嚴(yán)重，造成瓦楞紙板的厚度下降，紙箱的抗壓強(qiáng)度也隨之下降，導(dǎo)致紙箱的破損率增加。

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. 減少瓦楞的變形

3. Reduce the deformation of corrugated

，要控制好原紙的質(zhì)量，特別是瓦楞芯紙的環(huán)壓強(qiáng)度、水分等物理指標(biāo)。其次，對(duì)瓦楞紙板工藝進(jìn)行研究，改變因瓦楞輥的磨損、瓦楞輥間的壓力不足等因素導(dǎo)致的瓦楞變形。第三，改進(jìn)紙箱制造工藝，調(diào)整制箱機(jī)的送紙輥的間隙，以及將紙箱印刷改成柔性版印刷為主，以減少瓦楞的變形。同時(shí)也要注意紙箱的運(yùn)輸，盡量采用廂體車運(yùn)輸紙箱，減少因油布、繩子的捆扎和裝卸工的踩踏而引起瓦楞變形。

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. 設(shè)計(jì)合適的瓦楞紙板層數(shù)

4. Design appropriate layers of corrugated board

瓦楞紙板按其材料的層數(shù)可分單層、三層、五層、七層。隨著層數(shù)的增加，具有較高的抗壓強(qiáng)度和堆碼強(qiáng)度。因此，可根據(jù)商品的特征、環(huán)境參數(shù)及消費(fèi)者要求進(jìn)行選擇。

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. 加強(qiáng)對(duì)瓦楞紙箱剝離強(qiáng)度的控制

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

紙箱的瓦楞芯紙與面紙或里紙的粘合強(qiáng)度可通過(guò)檢測(cè)儀器來(lái)控制。如果剝離強(qiáng)度達(dá)不到標(biāo)準(zhǔn)要求，要尋找原因。要求供應(yīng)商加強(qiáng)對(duì)紙箱原材料的檢驗(yàn)，紙張的緊度、含水率指標(biāo)一定要符合有關(guān)標(biāo)準(zhǔn)。并通過(guò)提高粘合劑質(zhì)量、改進(jìn)設(shè)備等來(lái)達(dá)到國(guó)標(biāo)要求的剝離強(qiáng)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.
