The determination of the weight bearing limit of Industrial Garbage Bags is a process of comprehensive consideration of many factors, involving multiple links such as material properties, design structure and testing standards.
First of all, material properties are the basis. Commonly used materials for Industrial Garbage Bags, such as polyethylene and polypropylene, have a key influence on the bearing limit due to their basic physical properties. The tensile strength and tear strength of the material are important indicators. The tensile strength determines the ability of the garbage bag to withstand vertical tension. Through professional material tensile testing equipment, the maximum tensile force that the material can withstand before breaking can be measured. The tear strength reflects the resistance of the garbage bag to local tearing force, which is crucial to prevent sharp objects in the garbage from scratching the bag. For example, high-density polyethylene (HDPE) usually has higher tensile strength and tear strength than low-density polyethylene (LDPE), so garbage bags based on HDPE materials often have higher potential bearing limits.
Secondly, the design structure of the garbage bag should not be ignored. The size, shape and thickness of the garbage bag are closely related to the bearing limit. Generally speaking, larger garbage bags are more likely to break when carrying the same weight of garbage if there is no corresponding structural reinforcement. This is because the force distribution of garbage bags over a large area is more dispersed, and local forces are likely to exceed the bearing capacity of the material. The thickness of the garbage bag directly affects its overall strength, and thicker bags can bear greater weight. In addition, some special structural designs, such as bottom reinforcement and multi-layer composite structure, can effectively improve the carrying capacity of garbage bags. For example, the design of using double-layer materials or adding reinforcing ribs at the bottom can better withstand the pressure of heavy objects.
When determining the load limit, it is also necessary to verify it through rigorous testing. The common test method is to fix the garbage bag on a special test device in a laboratory environment, and then gradually increase the weight of the standard weight until the garbage bag shows obvious signs of damage such as rupture, tearing or deformation that cannot be used normally. This critical weight is the weight bearing limit of the garbage bag. During the test, different environmental factors such as temperature and humidity will also be considered. Because in a high temperature environment, the material may become soft and the strength will decrease; while in a low temperature environment, the material may become brittle and the toughness will decrease, which will change the actual load limit of the garbage bag. Only by combining material properties, structural design and test results can the weight bearing limit of Industrial Garbage Bags be accurately determined.
