PET Plastic Polymers

In today’s era, where sustainability and versatility are paramount, PET plastic polymers emerge as a solution that ticks all the right boxes. From packaging to textiles, PET offers a plethora of applications backed by its exceptional properties. But what is PET and why does it stand out as a must-buy polymer for food packaging applications?

In this blog, we will look at the fundamentals of PET plastic polymers, including their composition, properties, and various applications across industries. So, without further ado, read on! 

What is PET Plastic Polymer?

PET/PETE, or Polyethylene Terephthalate, is a type of thermoplastic polymer resin that is widely used in various industries. It belongs to the family of polyesters known for having a semi-crystalline form when stable. PET polymers are made through a process of extruding polyethylene and terephthalic acid, forming a long chain of repeating units. Because of its lightweight nature and ability to be recycled, PET has become increasingly popular as an environmentally friendly packaging solution.
