  • METHOD TO MAKE A COMPOSITE AUTOMOTIVE TRIM PART
    Publication number: 20190263033
    Abstract: The present invention relates to a method for producing a composite part, preferably an automotive trim composite part, comprising a textured skin and a rigid or foam substrate layer. The method comprises the steps of forming the skin by spraying or casting an aqueous thermoplastic dispersion which is derived from the melt blending of thermoplastic polymer, a dispersing agent, and water onto a textured mold and molding the rigid or form substrate onto the skin.

  • Flexible container with pop-up spout
    Patent number: 10173813
    Abstract: The present disclosure provides a flexible container. In an embodiment, the flexible container includes a first multilayer film and a second multilayer film. Each multilayer film comprises an inner seal layer. The multilayer films are arranged such that the seal layers oppose each other and the second multilayer film is superimposed on the first multilayer film. The multilayer films are sealed along a common peripheral edge. The flexible container includes an orifice in one of the multilayer films, and a pop-up spout extends through the orifice. The pop-up spout has a flange sealed to the multilayer film around the orifice. The pop-up spout comprises an ethylene/?-olefin multi-block copolymer.
