Publication number: 20240066552Abstract: Non-conductive films for constructing lighter than air balloons are provided. A non-conductive film may comprise multiple layers of gas barrier polymers. An outer surface printable layer and an interior heat or ultrasonically sealable layer may also be included. Each gas barrier film may comprise multiple (e.g., from 3 to approximately 75) barrier layers. A gas barrier core has a nano-layer structure. A gas barrier core may also comprise a biodegradable film or a bio-based film. A non-conductive film may comprise a metal layer for enhancing gas barrier properties. The metal layer may be discontinuous. The metal layer may be conductive and coated with an insulating top coat.Type: ApplicationFiled: November 6, 2023Publication date: February 29, 2024Applicant: San Diego Gas & Electric CompanyInventors: Eldridge M. MOUNT, III, Denis S. SANFORD
