Corrugated Box is widely used in logistics and commodity packaging, and its burst resistance is one of the important indicators for measuring the quality of cartons. Burst resistance is directly related to the stability and protection of cartons when subjected to external impact and internal pressure. Understanding the burst resistance of Corrugated Box is of great significance for selecting suitable packaging materials and ensuring the safe transportation of goods.
The burst resistance of Corrugated Box is affected by many factors. First of all, the material of corrugated cardboard is one of the key factors. High-quality base paper has high fiber strength and good toughness, and the corrugated cardboard made of it has a correspondingly high burst resistance. Different grades of base paper have obvious differences in burst resistance. Secondly, the structure and number of layers of corrugated paper will also affect the burst resistance. The burst resistance of Corrugated Box with different layers, such as three layers, five layers and seven layers, increases with the increase of the number of layers. In addition, the manufacturing process of the carton, such as bonding strength and pressure line quality, will also affect the burst resistance. If the bonding is not strong or the pressure line is unreasonable, it is easy to break when subjected to force.
A professional bursting tester is usually used to measure the bursting resistance of a corrugated box. During the test, the cardboard sample of the carton is fixed on the tester, and gradually increasing pressure is applied until the cardboard breaks. The tester will record the pressure value at the time of rupture, which is the bursting resistance of the cardboard. In order to ensure the accuracy and reliability of the test results, it is necessary to operate according to the standard test method and test multiple samples to take the average value. At the same time, the temperature and humidity of the test environment will also have a certain impact on the results, so the test should be carried out under the specified environmental conditions.
In practical applications, according to different types of goods and transportation requirements, it is necessary to select a corrugated box with appropriate bursting resistance. For fragile items or goods that need to be transported over long distances, cartons with higher bursting resistance should be selected to ensure that they can withstand various external force impacts and extrusions during transportation. In addition, during storage and handling, care should be taken to avoid excessive external force damage to the carton to maintain its good bursting resistance. At the same time, with the continuous development of packaging technology, some new corrugated box materials and structures are constantly emerging, which can further improve the bursting resistance and overall performance of the carton. In short, understanding the burst resistance of Corrugated Box and its influencing factors will help make more reasonable packaging choices in practical applications and ensure the safe transportation of goods.
