Recycled plastic bottles made into finely weaved yarn for lanyards. RPET stands for recycled polyethylene terephthalate, or recycled PET. PET is a strong, durable and recyclable material that is used for soda bottles, water bottles and food jars, while RPET can be made into such products as blankets, insulation, car parts, shoes and more. RPET is produced by collecting, sorting and recycling PET, then refining the material into flakes that can be turned into new products. Using RPET as an alternative to PVC is a huge step forward on the path toward a greener, safer and cleaner future.
