  • Antifog polyester lidding film for CPET trays
    Patent number: 11267233
    Abstract: The present disclosure is directed to peelable, heat-sealable lidding films for containers of diverse polymer compositions storing various products such as foodstuffs and pharmaceuticals. The lidding films disclosed herein can be heat-sealed to crystalline polyester trays (CPET), easily peeled, and contain improved antifogging performance by incorporating a non-migratory antifogging additive into the heat sealable layer of the film without deteriorating seal strengths.
    Type: Grant
    Filed: April 14, 2020
    Date of Patent: March 8, 2022
    Assignee: Toray Plastics (America), Inc.
    Inventors: Kari Shoolbraid, Takafumi Sakai

  • Heat sealing polyester films with low coefficient of friction
    Patent number: 10639873
    Abstract: Coextruded biaxially oriented sealable polyester films having at least one heat-sealable layer and at least one base layer. The heat-sealable layer has a sealing temperature on APET or PETG trays of at least 250° F. (121° C.) for seal strength of at least 1,500 g/in of film width, and a static and dynamic coefficient of friction of 0.28 or less. The heat-sealable layer includes one or more amorphous polyesters and one low melting point crystallizable polyester, such as polybutylene terephthalate (PBT).
