Jacob E. Napierala has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20230374206
    Abstract: The invention provides shrinkable films comprised of polyesters comprising certain combinations of glycols and diacids in particular proportions. These polyesters afford certain advantageous properties in the resulting shrinkable films, and thus are suitable as drop-in replacements for commercially available shrink films made using poly(vinyl chloride).
    Type: Application
