  • FILMS INCLUDING POST CONSUMER RESIN
    Publication number: 20230105510
    Abstract: Provided are films made from polymer blends including post-consumer resin (PCR). The films are formed from a polymer blend that includes a PCR, a low density polyethylene and/or ethylene/carbon monoxide copolymer (ECO copolymer), and a modification agent. The films, which include a PCR, contribute to improved sustainability and in aspects maintain or minimize the reduction of desirable properties, such as elastic recovery.

  • ADDITIVE MANUFACTURING USING RECYCLED POLYOLEFINS WITH OLEFIN BLOCK COPOLYMERS AND ARTICLES MADE THEREFROM
    Publication number: 20220306890
    Abstract: A method comprising, (i) providing a thermoplastic material comprising 5-75 wt % of a post-consumer recycled polyolefin composition and 25-95 wt % of an olefin block copolymer composition based on total weight of the thermoplastic material, wherein the post-consumer recycled polyolefin composition comprises at least 50 wt %, of a polyolefin and at least 0.1 wt % of a contaminant; (ii) heating and dispensing said thermoplastic material through a nozzle to form an extrudate deposited on a base, (iii) moving the base, nozzle or combination thereof while dispensing the thermoplastic material so that there is horizontal displacement between the base and nozzle in a predetermined pattern to form an initial layer of the material on the base, and (iv) repeating steps (ii) and (iii) to form a subsequent layer of the material adhered on the initial layer, and (v) optionally repeating step steps (ii) and (iii) to form additional subsequent layers.

  • Method and device for displaying locked interface and mobile terminal
    Patent number: 10321321
    Abstract: The present disclosure relates to a method and a device for displaying a locked interface, and a mobile terminal. The method includes: presenting an unlocking interface to a user, so that the user inputs an unlocking password through the unlocking interface; in a process of receiving the unlocking password, comparing a received part of the unlocking password with a set unlocking password to determine a correct degree value of the received part of the unlocking password; and displaying a locked content interface and/or the unlocking interface according to the correct degree value.
