Patent number: 11058791Abstract: A thin nanocomposite film for use in an absorbent article is provided. The film contains an ethylene polymer, a nanoclay having an organic surface treatment, and a compatibilizer that includes an olefin polymer containing an ethylenically unsaturated carboxylic acid monomer. The present inventors have discovered that through selective control over the particular type and concentration of the components used to form the film, as well as the manner in which it is formed, the modulus and tensile strength of the film can be significantly improved without having an adverse impact on its ductility.Type: GrantFiled: January 30, 2015Date of Patent: July 13, 2021Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Feng Chen, James Hongxue Wang, Gregory J. Wideman, Michael J. Faulks, Mark M. Mleziva

Publication number: 20200157329Abstract: A sustainable thermoplastic composition made by forming a mixture of virgin polypropylene and post-industrial-recycled material (PIR). The PIR may include a thermoplastic, elastomeric-polymer and a spunbond component. The mixture is melt-blended in an extruder. Extruded materials made from the mixture demonstrate little variance in the results of the IZOD Impact Test of materials containing 30 to 70 percent PIR, and a material containing 100 percent virgin polypropylene. In addition, the extruded materials containing 30 to 70 percent PIR demonstrate a substantially constant strain at yield, that strain at yield being substantially equal to that demonstrated by a material containing 100 percent virgin polypropylene.Type: ApplicationFiled: December 17, 2019Publication date: May 21, 2020Inventors: Brent Merrik Thompson, James Hongxue Wang, Gregory James Wideman

Patent number: 10131753Abstract: A multi-layered nanocomposite film for use in packaging is provided. More particularly, the film contains at least one core layer positioned adjacent to at least one outer layer. For example, in one embodiment, the film contains a core layer that is positioned between two outer layers. The core layer(s) and/or outer layer(s) may be formed from a polymer composition that contains an ethylene polymer, nanoclay having an organic surface treatment, and a compatibilizer that includes an olefin component and a polar component.Type: GrantFiled: January 30, 2015Date of Patent: November 20, 2018Assignee: Kimberly-Clark Worldwide, Inc.Inventors: James Hongxue Wang, Feng Chen, Gregory J.

Patent number: 9878065Abstract: A thin nanocomposite film for use in an absorbent article (e.g., sanitary napkin) is provided. The film contains a first ethylene polymer having a density of about 0.94 g/cm3 or less, second ethylene polymer having a density of greater than 0.94 g/cm3, and nanoclay having an organic surface treatment.

Patent number: 9617400Abstract: A film formed from a water-soluble polymer matrix containing a fragrance is provided. The film is water-sensitive so that upon contact with a sufficient amount of water, the matrix loses its integrity to increasingly expose the fragrance to the ambient environment for releasing its odor. The ability to incorporate a fragrance into the matrix is achieved by controlling the nature of the fragrance and polymer, the manner in which the matrix and fragrance are melt processed, etc. For example, the fragrance may be injected directly into the extruder and melt blended with the polymer to avoid the costly, time-consuming steps of pre-encapsulation or pre-compounding of the fragrance into a masterbatch. Furthermore, to balance the fragrance's ability to release the desired odor during use while minimizing the premature exhaustion of the odor during processing, the fragrance has a boiling point (at atmospheric pressure) of from about 125° C. to about 350° C.Type: GrantFiled: October 30, 2014Date of Patent: April 11, 2017Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Sarah A.
