Polyethylene Terephthalate (PET) is a clear, strong, and lightweight plastic widely used in beverage bottles, food containers, and synthetic fibers. It is fully recyclable under recycling code #1 and is one of the most commonly recycled plastics globally. PET is non-toxic, safe for food and beverage contact, and provides an excellent barrier against moisture and gases. Its durability and transparency make it ideal for packaging products ranging from water to salad dressings. Recycling PET reduces landfill waste and conserves resources, as recycled PET (rPET) can be turned into new bottles, clothing, or packaging materials. Many brands now use rPET to support sustainability goals, making PET a key material in circular economy initiatives.
