PET
PET (Polyethylene Terephthalate) is one of the most common plastic materials used in packaging, especially for beverage bottles and food containers. When you see this term in resumes or job descriptions, it usually refers to working with this type of plastic material in manufacturing, quality control, or design roles. It's popular because it's lightweight, strong, and can be recycled. Think of water bottles, soda containers, or food packaging – these are often made from PET. Other names you might see include PETE (an alternate abbreviation) or polyester (when used in fiber form).
