  • Publication number: 20210229408
    Abstract: Embodiments relates to a multilayer film comprising a core layer, a first outer layer and second outer layer. In an embodiment, the core layer includes a polypropylene; the first outer layer comprises (a) a polymethylpentene, (b) a butene copolymer, and (c) a polydimethylsiloxane and/or a crosslinked silicone; and the second outer layer comprises (a) a polymethylpentene, (b) a butene copolymer, and (c) a polydimethylsiloxane and/or a crosslinked silicone. Yet, another embodiment relates the core layer comprises polypropylene; the first outer layer comprises a mini random polypropylene resin, wherein the first outer layer comprises a first corona treated surface; and the second outer layer comprises a polymethylpentene copolymer, a crystalline polypropylene, a polydimethylsiloxane, a crosslinked silicone and/or a fluoropolymer.

  • Publication number: 20180244024
    Abstract: A release film including a monoaxially or biaxially oriented multilayer polyolefin-based film having a crystallizable polyolefin core film layer and at least one coextruded skin layer having a poly-4-methyl-1-pentene composition blended with an olefin copolymer elastomer modifier. The film's release surface has a peeling force value of 1500 g/inch or less and a 60° angle surface gloss of below 50 gloss units (GU). An embodiment is a film structure having (a) a metal transfer carrier film having polyolefin as described above and (b) a coated metal layer having a metal layer and a coating layer, wherein the coating layer lies between the metal layer and the metal transfer carrier film, wherein the metal transfer carrier film is configured to allow transfer of the coated metal layer onto a substrate, so that after transfer of the coated metal layer onto the substrate, the coating layer is located on top of the substrate.

  • Patent number: 6574197
    Abstract: A network monitoring device disposed at a node connected to a network includes a determination unit for sending a monitoring packet to a neighboring node upstream or downstream, and for determining that the neighboring node has broken away from the network unless the determination unit does not receive a response packet from the neighbor, and a notification unit for, when the determination unit has determined that the neighboring node upstream or downstream has broken away from the network, broadcasting a notification packet indicating the event to all other nodes connected to the network.
