How to strengthen the strength of vegetable packaging carton?

1、工作印刷和包裝行業(yè)的印刷方法主要包括：平版印刷，油墨彩印，凸版印刷油墨印刷（蔬菜包裝紙箱）。其中，蔬菜包裝紙箱水性印刷色差比高強(qiáng)度、低成本、效率高（快送），整體印刷效果接近于彩印，廣泛應(yīng)用于運(yùn)輸包裝產(chǎn)品。

1. The printing methods of the working printing and packaging industry mainly include: lithography, ink color printing, letterpress printing, ink printing (vegetable packaging carton). Among them, the color difference ratio of water-based printing of vegetable packaging cartons is high, with high intensity, low cost and high efficiency (fast delivery). The overall printing effect is close to color printing, which is widely used in transportation and packaging products.

2、蔬菜包裝紙箱的主要生產(chǎn)工藝是紙板自動(dòng)化生產(chǎn)線，印刷工藝，后加工成型工藝；印刷工作基本實(shí)現(xiàn)了印刷、開槽、模切、粘滯箱、包裝自動(dòng)化操作

2. The main production technology of vegetable packaging carton is paperboard automatic production line, printing technology and post-processing molding technology; The printing work has basically realized the automatic operation of printing, slotting, die cutting, sticky box and packaging

3、項(xiàng)目合理設(shè)計(jì)蔬菜包裝紙箱長度、寬度、高度及比例

3. Reasonable design of width and height of carton for vegetables

大量的數(shù)據(jù)分析表明，蔬菜包裝紙箱的抗壓強(qiáng)度和周長、蔬菜包裝紙箱的高度和寬度都與一定的關(guān)系有關(guān)。蔬菜包裝紙箱周長越長，抗壓強(qiáng)度高，蔬菜包裝紙箱周長，具有一定的抗壓強(qiáng)度轉(zhuǎn)換關(guān)系。蔬菜包裝紙箱，一般來說，寬比，在1~1.8寬比的范圍內(nèi)，抗壓強(qiáng)度的影響僅為+百分之五RL=1.2~1.2的長寬比，蔬菜包裝紙箱抗壓強(qiáng)度值是比較高的。箱體比例為2:1時(shí)，抗壓強(qiáng)度下降了百分之二十左右，所以蔬菜包裝紙箱的設(shè)計(jì)在長寬比不超過2時(shí)，否則會(huì)造成很大的浪費(fèi)。

A large number of data analysis shows that the compressive strength and perimeter of vegetable packaging carton, the height and width of vegetable packaging carton are related to a certain relationship. The longer the perimeter of the vegetable packaging carton, the higher the compressive strength. The perimeter of the vegetable packaging carton has a certain compressive strength conversion relationship. Generally speaking, the width ratio of vegetable packaging carton is in the range of 1 ~ 1.8, and the impact of compressive strength is only + 5%, RL = 1.2 ~ 1.2. The compressive strength of vegetable packaging carton is relatively high. When the box ratio is 2:1, the compressive strength decreases by about 20%. Therefore, when the length width ratio of vegetable packaging carton is no more than 2, it will cause great waste.

4、蔬菜包裝紙箱包裝廠合理堆放時(shí)間和堆放方式

4. Reasonable stacking time and method of vegetable packaging carton packaging factory

（1）蔬菜包裝紙箱抗壓強(qiáng)度隨著時(shí)間的延長而減小，這種現(xiàn)象稱為疲勞現(xiàn)象。試驗(yàn)表明，在長時(shí)間的載荷作用下，只要經(jīng)過一個(gè)月的時(shí)間，紙盒的抗壓強(qiáng)度將下降百分之三十。一年后，其抗壓強(qiáng)度僅為初始值的百分之五十。

(1) The compressive strength of vegetable packaging carton decreases with the extension of time, which is called fatigue phenomenon. The test shows that under the action of long-term load, the compressive strength of carton will decrease by 30% after one month. After one year, the compressive strength is only 50% of the initial value.

（2）蔬菜包裝紙箱堆垛法對(duì)蔬菜包裝紙箱抗壓強(qiáng)度也有一定影響。蔬菜包裝紙箱軸向應(yīng)力明顯高于水平孔方向，堆垛箱應(yīng)保持軸向壓縮。從實(shí)驗(yàn)結(jié)果來看，箱內(nèi)壓在墻角的位置上，距離較低的軸承壓角較遠(yuǎn)。因此，蔬菜包裝紙箱應(yīng)該盡量保持角落，以便在堆疊時(shí)保持一致。

(2) The stacking method of vegetable packaging cartons also has a certain impact on the compressive strength of vegetable packaging cartons. The axial stress of the vegetable packaging carton is significantly higher than that of the horizontal hole, and the stacking carton should maintain axial compression. From the experimental results, it can be seen that the pressure angle of the lower bearing is far away when the box is pressed on the corner of the wall. Therefore, vegetable packaging cartons should be kept in corners as far as possible in order to keep consistent during stacking.
