Publication number: 20230294387Abstract: A multilayer membrane comprising at least two co-extruded layers where the two co-extruded layer contain different polymers and one of the two co-extruded layers contains an extrusion additive. Examples of useful extrusion additives may include a nucleating agent or a pore-forming particulate. A method for making the membrane is also disclosed. Using an extrusion additive when co-extruding two different polymers avoids some of the drawbacks associated with processes involving the co-extrusion of different polymers, particularly processes where a co-extruded non-porous precursor is later stretched to form pores. For example, the drawback of lower permeability, difficulty to make lower Gurley, and splittiness may be improved.Type: ApplicationFiled: July 5, 2021Publication date: September 21, 2023Inventors: Changqing Wang ADAMS, David ANZINI

Patent number: 9260225Abstract: The disclosure relates to a zipper for a reclosable bag wherein the zipper is designed to make additional sound during operation, and further provide an increased tactile response. The zipper profile is manufactured by forming cuts in the profile, and then the profile is stretched so that the cuts become gaps. These gaps cause additional sound during operation of the zipper.Type: GrantFiled: November 29, 2011Date of Patent: February 16, 2016Assignee: ILLINOIS TOOL WORKS INC.Inventors: David Anzini, Rusty Koenigkramer, Eric Plourde, Kenny McCracken, Steven Ausnit, Charles G.

Patent number: 9027310Abstract: The method and apparatus relates to providing a slit, perforation, line of weakness or similar structure in a flange of a zipper for a reclosable package or bag, including a high-capacity zipper. The slit, perforation, line of weakness or similar structure provides an opening for filling the reclosable package or bag without the need to separate the zipper profiles from each other. After filling, the opening is sealed and the cosmetic appearance of the reclosable package or bag is maintained.Type: GrantFiled: February 15, 2012Date of Patent: May 12, 2015Assignee: Illinois Tool Works Inc.Inventors: Glyn Russell, Charles Greco, Lars Wihlborg, Robert J.

Publication number: 20140069061Abstract: The disclosure pertains to method for manufacturing reclosable packages, bags or pouches using a flow wrapper machine wherein, typically, a self-mating reclosure or zipper sealed inside of the package. In a first embodiment, self-mating reclosures are placed transversely on the web and a flow wrapping machine wraps the web around the food product thereby forming a machine direction fin seal. Transverse direction end seals are likewise formed. In a second embodiment, the web includes quad seals formed by a drag sealer at positions which will become corners of the package. Similar to the method of the first embodiment, the flow wrapping machine wraps the web around the food product thereby forming a fin seal.Type: ApplicationFiled: November 14, 2013Publication date: March 13, 2014Applicant: ILLINOIS TOOL WORKS INC.Inventor: David ANZINI

Publication number: 20070225141Abstract: The present disclosure relates to methods for forming reclosable bags with slider zippers which can be used in high pressure pasteurization. In particular, these methods form reclosable bags with a shroud formed over the slider zipper, with a patch or cap for protecting the slider during high pressure pasteurization. When the user tears the shroud from the bag, the patch or cap remains attached to the shroud but releases from the slider. An alternative embodiment forms an air pocket in the shroud to protect the slider.Type: ApplicationFiled: May 15, 2007Publication date: September 27, 2007Inventors: David Anzini, Steven Ausnit, Lars Wihlborg, Per Bentsen, Robert Kobetsky
