What is the Difference between PLA and PE Plastic?

Both PLA and PE plastics are ubiquitous materials used in the manufacturing industry. Though they are polymers with similar properties, they stem from different chemical compositions and exhibit characteristics that vary in scope. In this article, we'll illustrate the differences between PLA and PE plastic.

 

PLA Plastic

 

Polylactic acid (PLA) plastic is a biodegradable thermoplastic that is derived from renewable sources such as corn, sugarcane, and potato. The material does not contain any toxic or hazardous substances and is environmentally safe, making it a favorable option for several applications. Its versatility and usability have its plastic sheets utilized in the manufacture of disposable plastics, food packaging, medical equipment, and 3D printing.

 

One of the notable properties of PLA plastic is its ability to biodegrade. When subjected to the right conditions of moisture and heat, it decomposes back to carbon dioxide and water. This property has made it a go-to option for environmentally-friendly packaging solutions.

 

PE Plastic

 

Polyethylene (PE) plastic is a highly versatile thermoplastic polymer that is made from petroleum. It is presently one of the most extensively used plastics globally, serving a wide array of industries. Its good impact strength, lightweight, low thickness, and temperature resistance make it a favorable material in several applications, including construction, automotive, and packaging.

 

One of the most notable characteristics of PE plastic is its recyclability. The material can be repurposed into a wide array of products, including packaging, synthetic wood, and plastic bags.

 

Differences Between PLA and PE Plastic

 

The primary distinctions between PLA plastic and PE plastic are in their chemical composition, usability, and biodegradability. While PLA is derived from renewable resources, PE plastic comes from petroleum. PLA is a biodegradable material, while PE plastic is easily recyclable.

 

PLA plastic is mostly used in the manufacture of products that are environmentally safe, while PE plastic is extensively utilized in a wide range of applications worldwide. The two plastics exhibit varying properties, making them suited for different applications.

 

Conclusion

 

PLA and PE plastic are essential materials in the manufacturing industry. Although they possess similar properties, the differences between them are significant. PLA plastic is environmentally safe, biodegradable, and is mostly utilized in products that are environmentally friendly. On the other hand, PE plastic is highly recyclable and commonly used in several fields. Understanding the differences between the two plastics will affect informed decisions regarding their applications.
