How does the material of a Garbage Bag affect its load-bearing capacity and durability?

Garbage Bags play an important role in our daily lives, and their material is a key factor in determining their load-bearing capacity and durability.
Common Garbage Bag materials include polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC). Polyethylene Garbage Bags usually have good flexibility and ductility. The molecular structure of this material is relatively regular, so that the Garbage Bags made of it can have a certain amount of expansion and contraction space when subjected to external forces, thereby improving its load-bearing capacity to a certain extent. Moreover, polyethylene has good chemical stability and is not easily corroded by substances such as acids and alkalis, so its durability is relatively high.
Polypropylene Garbage Bags have higher strength and hardness. Its molecular chain is more regular and has a higher degree of crystallinity, which allows polypropylene Garbage Bags to bear greater weight without breaking easily. However, relatively speaking, the flexibility of polypropylene may be slightly inferior, and it may crack when dealing with sharp objects or large external forces.
Garbage Bag made of polyvinyl chloride has good wear and puncture resistance. This means that it is not easy to be scratched or worn when facing sharp or rough garbage, which improves durability. However, it may release harmful substances in high temperature environments, and its environmental performance is relatively poor.
In addition, the thickness of the material is also an important factor affecting the load-bearing capacity and durability of the Garbage Bag. Generally speaking, under the same material, the greater the thickness, the stronger the load-bearing capacity of the Garbage Bag and the more durable it is.
In general, the material of the Garbage Bag directly affects the load-bearing capacity and durability of the Garbage Bag by determining its molecular structure, physical properties and chemical properties. When choosing a Garbage Bag, we should consider factors such as material and thickness according to actual use needs to purchase products that meet our needs.
