1、侧压强度测试：直接影响瓦楞纸箱的支撑强度，瓦楞纸箱主要受重力作用，侧压是评估混凝土强度的方法。
1. Side pressure strength test: it directly affects the support strength of corrugated box. Corrugated box is mainly affected by gravity, and side pressure is the best method to evaluate concrete strength.
2、断裂强度测试：影响瓦楞纸箱的侧面支撑强度 -
2. Breaking strength test: influencing the side support strength of corrugated box-
瓦楞纸箱保护产品，抗破损性是板材每单位面积可吸收和均匀增加的压力值。此测试用于检查纸箱在实际运输环境中承受静态局部压缩的能力。
The corrugated box protects the product, and the damage resistance is the maximum pressure value that can be absorbed and evenly increased per unit area of the board. This test is used to check the ability of the carton to withstand static local compression in the actual transportation environment.
3、粘接强度测试：粘接强度不足容易引起分层，大大降低了纸箱的抗压强度。
3. Bonding strength test: insufficient bonding strength is easy to cause delamination, which greatly reduces the compressive strength of the carton.
4、厚度测试：如果在纸板加工过程中波纹高度损失太大，例如模切，即压痕，开槽或印刷，则会大大减少。纸箱的抗压强度，因此保持瓦楞纸板的厚度应该是生产过程的关键部分。
4. Thickness test: if the corrugated height loss in paperboard processing is too large, such as die cutting, that is, indentation, slotting or printing, it will be greatly reduced. Therefore, maintaining the thickness of corrugated board should be a key part of the production process.

5、水分含量测试：指瓦楞纸或纸板的含水量。水分含量对纸箱的强度有很大影响。它是纸箱的三个重型缺陷检测项目之一。如果水分含量太低，纸张太脆，压制时容易破碎，抗折性也差。如果瓦楞纸的含水量太大，单面机加工的瓦楞纸板容易卷曲，扭曲时可能会发生起泡和脱胶。
5. Moisture content test: refers to the moisture content of corrugated paper or paperboard. The moisture content has a great influence on the strength of the carton. It is one of the three heavy defect detection items of carton. If the moisture content is too low, the paper is too brittle, easy to break when pressed, and the folding resistance is poor. If the moisture content of the corrugated paper is too large, the corrugated paperboard machined on one side is easy to curl, and blistering and degumming may occur when it is twisted.
6、摇盖折叠测试：是纸箱检测中非常重要的指标，它可以显示纸箱的质量。
6. Flap folding test: it is a very important index in carton detection, it can show the quality of carton.
