  • Moisture, Grease, and Oil Resistant Coatings for Cellulosic Materials
    Publication number: 20210292590
    Abstract: A coated cellulose-based food or beverage container that is resistant to penetration by oil and grease in the presence of water. The container may be coated with a starch dispersion that includes a starch having an amylose content of 20% by weight to 100% by weight (e.g., 30% by weight to 50% by weight). Methods for producing the coated container include preparing a starch suspension, heating the starch suspension to form a starch dispersion, applying the heated starch dispersion to the container to form a coating, and drying the coating.

  • Biodegradable polyester and natural polymer laminates
    Patent number: 6893527
    Abstract: Methods of making articles are provided in which a self-supporting structure formed of natural polymer has a self-adherent, moisture resistant thermoplastic film comprising gelatinized starch and a hydroxy-functional polyester on the structure surface. The self-supporting structure preferably is a starch and polyvinyl alcohol blend in an expanded form. The articles typically do not delaminate even when soaked in water, and are biodegradable.
