Publication number: 20230081107Abstract: Thin, self-supporting biaxially expanded polytetrafluoroethylene (ePTFE) membranes that have a high crystallinity index, high intrinsic strength, low areal density (i.e., lightweight), and high optical transparency are provided. In particular, the ePTFE membrane may have a crystallinity index of at least about 94% and a matrix tensile strength at least about 600 MPa in both longitudinal nd transverse directions. In addition, the ePTFE membrane is transparent or invisible to the naked eye through a complete conversion of the PTFE primary particles into fibrils. The ePTFE membrane may have a thickness per layer of less than 100 nm and a porosity reater than 50%. Further, the ePTFE membrane is stackable, which, in turn, may be used to control permeability, pore size, and/or bulk mechanical properties. The ePTFE membrane may be used to form composites, laminates, fibers, tapes, sheets, tubes, or three-dimensional objects. Additionally, the ePTFE membrane may be used in filtration applications.Type: ApplicationFiled: June 9, 2020Publication date: March 16, 2023Inventors: Bryan Hutchinson, Justin J. Skaife, Bret Snyder

Patent number: 11517504Abstract: A method of making a storage bag comprising the following steps performed in any order: (a) forming a composite tube having an inner surface comprising a higher melting polymer, an outer surface comprising a lower melting polymer, two ends, and a diameter; (b) flattening the tube in a direction perpendicular to the diameter; (c) forming a joint at one of the ends at a temperature between respective melting points of the higher melting polymer and the lower melting polymer; (d) providing a composite sheet having a first side comprising a higher melting polymer and a second side comprising a lower melting polymer; and (e) disposing the composite sheet over the joint such that the first side comprising a lower melting polymer engages the joint and forming a lap seam over the joint at a temperature between respective melting points of the higher melting polymer and the lower melting polymer, and a storage bag made by such method.Type: GrantFiled: January 30, 2020Date of Patent: December 6, 2022Assignee: W. L. Gore & Associates, Inc.Inventors: Bret A. Snyder, Basak Irem Nase, John E. Bacino, William Shamrock

Patent number: 11278471Abstract: A storage bag configured to contain or that contains at least one therapeutic compound such as a viral vector and non-viral vector is provided. In one embodiment, the storage bag contains a viral vector and/or a non-viral vector containing genetic material. The storage bag has two edges and two ends including a first face and a second face integrally joined at the two edges of the bag and defining an inner surface and an outer surface forming the bag; the inner surface including a higher melting polymer, and the outer surface including a lower melting polymer; a joint at one of the ends; a discrete composite sheet having a first side including a higher melting polymer and a second side including a lower melting polymer folded over the joint with the first side including a lower melting polymer engaging the joint to form a lap seam over the joint.Type: GrantFiled: November 21, 2019Date of Patent: March 22, 2022Assignee: W. L. Gore & Associates, Inc.Inventors: Bret A. Snyder, Basak Irem Nase, John E. Bacino, William Shamrock, Edward Gunzel
