Polyester vs. Polyethylene: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Polyester is a synthetic fiber used in textiles, while polyethylene is a plastic polymer used in various products like containers and bags.
Key Differences
Polyester is a category of polymers used predominantly in clothing, bedding, and furnishings. It's known for its durability, resistance to stretching and shrinking, and quick-drying properties. Polyethylene, in contrast, is the most common plastic, used in making plastic bags, bottles, and containers. It's appreciated for its strength, flexibility, and moisture resistance.

Polyester fabrics are created from ethylene-derived compounds, often mixed with natural fibers to produce clothes that are wrinkle-resistant and maintain their shape. Polyethylene is made by polymerizing ethylene and is used in both rigid forms (like containers) and flexible forms (like plastic bags).
