Packaging compressive strength refers to the load and deformation until the box is broken after the dynamic pressure is uniformly applied on the pressure testing machine. The overall performance of cartons is directly reflected here. Here is a simple introduction to the compressive strength of carton packaging.

紙箱體的抗壓強(qiáng)度受到以下因素的影響：

The compressive strength of the carton body is affected by the following factors:

1.紙箱包裝是用各種紙組成的，合理搭配是保證紙箱抗壓強(qiáng)度的基本條件。

1. carton packaging is composed of various papers. Reasonable matching is the basic condition to ensure the compressive strength of cartons.

測試過每一層紙的物理性能后，我們就可以開始計(jì)算紙箱的抗壓強(qiáng)度，然后在生產(chǎn)過程中的每一道工序進(jìn)行抗壓強(qiáng)度的計(jì)算，來控制紙箱的抗壓強(qiáng)度。

After testing the physical properties of each layer of paper, we can start to calculate the compressive strength of the carton, and then calculate the compressive strength of each process in the production process to control the compressive strength of the carton.

2.紙張的環(huán)壓強(qiáng)度對(duì)保證紙箱抗壓強(qiáng)度關(guān)重要，但紙張的其它物理性能也不可忽略。

2. the annular compressive strength of the paper is very important to ensure the compressive strength of the carton, but other physical properties of the paper can not be ignored.

紙，尤其是楞紙的抗張強(qiáng)度不能滿足時(shí)，紙箱包裝在抗壓測驗(yàn)中會(huì)呈現(xiàn)力值與變形量一向平穩(wěn)遞加，而有效能值較低，紙箱包裝在抗壓測驗(yàn)中會(huì)呈現(xiàn)力值與變形量一向穩(wěn)定遞加。紙的防水性能也很重要，尤其是箱體對(duì)紙的防水性能要求較高，有時(shí)雖然紙箱的抗壓強(qiáng)度很高，但由于紙張不防水，紙箱放在冷庫中會(huì)吸潮，形成塌庫。

When the tensile strength of paper, especially corrugated paper, cannot be satisfied, the force value and deformation of carton packaging will always increase steadily in the compression test, while the effective energy value is low. The force value and deformation of carton packaging will always increase steadily in the compression test. The waterproof performance of paper is also very important. In particular, the box has high requirements for the waterproof performance of paper. Sometimes, although the compressive strength of the carton is very high, because the paper is not waterproof, the carton will absorb moisture in the cold storage and form a collapse.

3.包裝紙箱生產(chǎn)過程還對(duì)抗壓強(qiáng)度形成影響。

3. the production process of packaging carton also has an impact on the compressive strength.

經(jīng)試驗(yàn)，在相同條件下，紙箱每加寬1mm，紙箱抗壓強(qiáng)度下降90N~130N，變形量約為2mm.壓線過寬，紙箱包裝將形成每加寬1mm的紙箱包裝，并使其變形量變大，有效能值小，變形量大。為了保證抗壓強(qiáng)度，我們應(yīng)努力提高生產(chǎn)工藝，降低各工序?qū)埾淇箟簭?qiáng)度的影響。

According to the test, under the same conditions, the compressive strength of the carton decreases by 90n~130n and the deformation is about 2mm for every 1mm of carton width If the pressing line is too wide, the carton packaging will form a carton packaging with each widening of 1mm, and make its deformation larger, with small effective energy value and large deformation. In order to ensure the compressive strength, we should strive to improve the production process and reduce the impact of various processes on the compressive strength of cartons.

4.根據(jù)紙箱箱型選擇合適的楞型也是非常重要的。

4. it is also very important to select the appropriate ridge type according to the carton type.

一般認(rèn)為楞型越大，紙箱壓縮強(qiáng)度就越高，容易忽略楞型對(duì)變形量的影響。拉坯形狀越大，紙箱壓縮強(qiáng)度越大，變形量越大；楞型越小，紙箱壓縮強(qiáng)度越小，變形越小。如果紙箱太大，楞形卻很小，紙箱在測壓抗壓測試時(shí)很容易被壓垮；紙箱太小，紙板形狀卻很大，抗壓測驗(yàn)時(shí)會(huì)形成變形量過大，緩沖過程長，有效能值與紙箱的抗壓性差。

It is generally believed that the larger the ridge, the higher the compression strength of the carton, and it is easy to ignore the influence of the ridge on the deformation. The larger the blank shape, the greater the compression strength and deformation of the carton; The smaller the ridge, the smaller the compression strength of the carton and the smaller the deformation. If the carton is too large and the ridge shape is very small, the carton is easy to collapse during the pressure and compression test; The carton is too small, but the shape of the cardboard is very large. During the compression test, the deformation will be too large, the cushioning process will be long, and the effective energy value is poor with the compression resistance of the carton.

5.水分對(duì)紙箱抗壓強(qiáng)度的影響更不容忽視。

5. the influence of moisture on the compressive strength of cartons should not be ignored.

箱體的生產(chǎn)環(huán)境、寄存環(huán)境、使用環(huán)境、氣候、氣候等因素對(duì)紙箱含水率產(chǎn)生影響，為了保證紙箱抗壓強(qiáng)度，應(yīng)盡量避免外界環(huán)境對(duì)紙箱含水率的影響。

The production environment, storage environment, use environment, climate, climate and other factors of the box have an impact on the moisture content of the box. In order to ensure the compressive strength of the box, try to avoid the impact of the external environment on the moisture content of the box.
