In the modern logistics and packaging industry, plastic packaging containers play a vital role. Not only do they need to have good mechanical properties to protect the integrity of the internal product, they also need to be stable under a variety of environmental conditions. Among them, the drop test, as an important mechanical property test, plays a decisive role in the quality and safety of plastic packaging containers. In this paper, we will discuss the relevant contents of the drop test in the solid tank at normal temperature and the drop test in the empty tank at low temperature.
Solid tank drop test at normal temperature
The drop test of solid container at room temperature is a common test method, which aims to simulate the accidental fall that plastic containers may face under normal operating conditions. During the test, the plastic container will be filled with the actual contents or the simulation, and will be dropped freely from a certain height. This process usually uses the bottom drop method, which means that the container lands on the bottom. The test requires that cracks are not allowed after falling, which is to ensure the structural integrity of the container to prevent damage or leakage of internal products.
Low temperature empty tank drop test
Different from the solid tank drop test at normal temperature, the low temperature empty tank drop test pays more attention to the cold resistance of plastic containers in low temperature environment. In this test, the plastic container is pre-placed in a low temperature environment for a period of time to bring it to the test temperature. The container then falls freely from a certain height so that its bottom and sides land separately. Such tests are designed to assess the toughness and impact resistance of plastic materials at low temperatures.
Drop tests on different types of plastic packaging containers
For different types of plastic packaging containers, the specific requirements of the drop test will be different. Taking bottles and buckets as an example, the test method requirements are relatively complex. First, the container is filled with a certain temperature of water and dropped from a certain height with the bottom and side respectively to the concrete floor. In this process, there should be no damage and leakage to ensure that the container can effectively carry and protect the internal liquid during transportation.
The importance of drop tests
As an important means of quality control of plastic packaging containers, drop test can not only evaluate its structural strength and impact resistance, but also provide effective feedback for product design and improvement. By continuously optimizing the design and material selection, the durability and safety of plastic packaging containers can be improved, and the occurrence of product damage and leakage caused by falling can be reduced, thereby reducing business operating costs and improving user experience.
To sum up, drop test plays an irreplaceable role in the production and quality control process of plastic packaging containers. By strictly complying with the standards and requirements of the drop test, it is possible to ensure that the plastic packaging container can be stable and reliable transport and storage of internal products in a variety of use environments. Therefore, strengthening the research and implementation of drop tests is of great significance for improving the quality and competitiveness of plastic packaging containers.
