  • Patent number: 12264243
    Abstract: The present invention relates to a biaxially oriented formable polyester film having A/B/A layer structure and the process of preparing the same. The biaxially oriented formable polyester films exhibit improved Dart impact, elongation and formability comparable to nylon film which are used for thermoforming and cold forming applications.

  • Patent number: 12109749
    Abstract: The present disclosure relates to a process for producing bi-axially oriented polyester (BOPET) film from the recycled polyethylene terephthalate (RPET) granules. The process involves preparing recycled PET (RPET) granules form post-consumer recycled PET (PCR PET) by depolymerization and polycondensation followed by preparing the biaxially oriented polyethylene terephthalate (BOPET) film having recycled polyethylene terephthalate (RPET) up to 100%. The bi-axially oriented polyester film has good elongation, mechanical and/or thermal properties and are similar in quality to virgin PET films useful in high end food and pharma packaging and industrial applications.
