The world has known plastic as an unparalleled material that can help transform our lives for the better and as an alternative for many of the natural raw materials available in the environment targeting to preserve various environmental resources and raw materials. In 1973, Du Pont Chemical Company introduced the first plastic bottle made from PET. The study deals with the importance of polyethylene terephthalate panels (PET) in the field of product design and the way of using and employing them for better product characteristics and properties, in order to ensure safe disposal of plastic waste and preserve our environment. PET panels is considered one of the important materials in the field of product design that can be used for products improvement especially in terms of endurance; durability, thermal insulation, sound insulation, transparency, and aesthetic appearance. PET panels also play an important role in reducing product costs and ensuring safe disposal of some plastic waste. Though and through the findings, PET Panels are suggested to be used in the field of product design as an alternative for many of the currently used materials for their cheap price and eco-friendly impact to ensure improving of the properties of products and achieving a safe disposal of plastic waste.
