PET, which stands for polyethylene terephthalate, is a clear, strong and lightweight plastic belonging to the polyester family.
PET is typically called “polyester” when used for fibers or fabrics, and “PET” or “PET Resin” when used for bottles, jars, containers and packaging applications.
PET is the world’s packaging choice for many foods and beverages because it is hygienic, strong, lightweight, shatterproof, and retains freshness. It is most commonly used to package carbonated soft drinks and water. Consumers can identify PET containers by the triangular #1 resin identification code found on the bottom of PET bottles and jars.
