Patent number: 11801670Abstract: A squeezable, white polypropylene film is disclosed having a novel balance of conformability, stiffness, modulus, opacity, and whiteness. The film includes an ABCBA structure having a core layer of polypropylene resin with an elastomeric copolymer and a cavitating agent. Two intermediate layers of polypropylene resin are present on either side, the intermediate layers optionally including an elastomeric copolymer and a pigmenting agent. Two polymer skin layers surround the two intermediate layers. The resins are co-extruded into a biaxially oriented film having a thickness between 40 to 70 pm for use in pressure-sensitive labeling applications.Type: GrantFiled: August 24, 2018Date of Patent: October 31, 2023Assignee: Jindal Films Americas LLCInventors: Benoît Ambroise, Daniel L. Hinman, Robert M. Sheppard, Michael D. Cleckner

Patent number: 11752746Abstract: Disclosed are compositions, methods, and uses for multi-layered films which are intended to provide high quality sealants having sufficient sealing strength for use in packaging and other applications while being more cost-effective and higher-yield than traditional combinations of unoriented polyolefin films and web materials. The film comprises a multilayer structure of LLDPE having a core layer, a surface skin layer, and a sealant skin layer. The core layer further comprises a slip agent, while the skin layers further comprise antiblock agents. Optional embodiments may include tie layers between the core layer and the skin layers, or may include pigments in one or more of the core layer or tie layers. The surface skin layer may be subjected to a surface treatment (e.g., corona treatment) to improve suitability for coating or metallization.Type: GrantFiled: August 24, 2018Date of Patent: September 12, 2023Assignee: Jindal Films Americas LLCInventors: Benoît Ambroise, Michael D. Cleckner, Christophe E. Guillaume, Lesley A. Bliss

Patent number: 8844248Abstract: Provided is a method for forming a bag around an article, the method comprising: providing an oriented film; cauterizing the film at a temperature sufficient to de-orient a portion of the film to create a cauterized area on the continuous film; placing an article(s) on the film between adjacent cauterized areas; heat-sealing the film around the article(s) such that at least a portion of the film between the heat-sealed area and the article comprises the cauterized area. Also, provided is a form, fill, and seal apparatus comprising a heat sealer and a cauterizer, both having a temperature control, the heat sealer positioned to allow the heat sealer to form a seal between two edges of film having an article wrapped therein, and the cauterizer positioned to cauterize an area of the sealed film in an area adjacent to the sealed edges and the article.Type: GrantFiled: July 12, 2012Date of Patent: September 30, 2014Assignee: Jindal Films Americas LLCInventors: Michael D. Cleckner, Scott Wilkins, James S. Howard

Publication number: 20110236668Abstract: Disclosed are single and multi-layer films having low haze and low density properties, comprising at least one polymeric layer and at least one density reduction agent, wherein the film has a haze ?35% and a density (D) of at least 1% lower than the density of the polymer. The density reduction agent may be added to, for example, a core layer, one or more tie layers, or a core layer and one or more tie layers. Processes for the manufacture of these films, and the use of these films as labels and packaging products are disclosed.Type: ApplicationFiled: September 23, 2009Publication date: September 29, 2011Inventors: Michael J.
