Recycled Polyethylene Terephthalate Sheet (R-PET) The material is composed of either 100% recycled PET flake OR both recycled PET flake and virgin PET material at percentages specified by the customer. R-PET is produced by collecting, sorting and recycling PET, then refining the material into flakes that can be turned into new products. Using R-PET as an alternative to PVC is a huge step forward on the path toward a greener, safer and cleaner future. R-PET Sheet with tight tolerances is ideal for packaging, laminating, and custom thermoforming applications. R-PET films are best suited for rigid packaging applications in industries ranging from food and medical to automotive. Compared to plastic resins such as PP, PVC and HDPE, R-PET materials have high tensile yield strengths.
