Polyethylene terephthalate, commonly known as PET, is a type of plastic widely used in packaging, especially for bottles and containers. It is known for its strength, lightweight nature, and resistance to moisture, making it ideal for storing beverages and food products. PET is also recyclable, which helps reduce environmental impact. In addition to packaging, PET is used in textiles, where it is often found in polyester fabrics. Its durability and ability to hold color make it a popular choice in the fashion industry. Overall, PET plays a significant role in both consumer goods and sustainable practices.
