Patent number: 12251908Abstract: The biaxially oriented multilayered films include a stack (A-B)n of n layer units A-B, where n is greater than or equal to 32 each layer unit A-B having individual layers comprising a first layer A and a second layer B overlying the first layer A. The biaxially oriented multilayer films include intralayer voids within a portion of the individual layers in the stack. The intralayer voids have width-to-height aspect ratios from 20:1 to 500:1. The first layers of the layer units have a first composition, and the second layers of the layer units have a second composition. The first composition includes a first thermoplastic and a first polymer immiscible with the first thermoplastic. The second composition includes a second thermoplastic that may be the same as or different from that of the first thermoplastic.Type: GrantFiled: August 5, 2020Date of Patent: March 18, 2025Assignee: FLEX FILMS (USA) INC.Inventors: Steven Sargeant, David Ortiz-Grob, Dakota Goodman

Patent number: 12168340Abstract: Embodiments of the disclosure relate to a blister package having a laminate structure that is heat-sealable to a lacquer layer on strain-hardened aluminum foil. The blister package includes a lid layer comprising a strain-hardened aluminum foil, a lacquer layer on a sealing surface of the strain-hardened aluminum foil and a laminate structure sealed directly to the lacquer layer. The laminate structure includes a multilayer film and a plurality of wells formed therethrough. The multilayer film includes a first formable layer of a thermoplastic material and a sealing layer of a copolyester material. The sealing layer overlies the first formable layer and has an outer surface opposite the first formable layer. The sealing layer has crystallinity from 5% to 20% as measured by differential scanning calorimetry (DSC). The outer surface of the sealing layer is sealed directly against the lacquer layer.Type: GrantFiled: May 26, 2020Date of Patent: December 17, 2024Assignee: Flex Films (USA), Inc.Inventors: Ashok Chaturvedi, Steven Sargeant, Sudhir Naik, Sanjeev Gupta, Dipak Boral, Pramod Sirsamkar
