RPET stands for Recycled Polyethylene Terephthalate. It's a material derived from recycling PET (Polyethylene Terephthalate) plastic, which is commonly used in the production of bottles for beverages, food containers, and other packaging materials. RPET is created by collecting and processing post-consumer PET plastic waste, such as bottles, and then melting and reforming it into new products. RPET is often used in the production of textiles, such as clothing and carpets, as well as in packaging and other applications where a recycled, environmentally friendly material is desired.
