  • Patent number: 10172369
    Abstract: The present invention relates to thermoplastic cheese packaging films having an outer sealant layer having a three-dimensional food-contact surface topography formed by a roughening agent dispersed within the polymer matrix of the sealant layer. When the hot processed cheese contacts the surface of the sealant layer and cools, the cheese is embossed by inverse replication of the surface topography of the sealant layer. Such films are particularly useful when used with high speed hot packaging operations.

    Abstract: A multilayer film that includes at least three layers and is made up of a first layer, a second layer and a third layer, where the first layer is in between the second and third layers. The first layer contains a blend of a second polyolefin and interpolymer resin particles that include a styrenic polymer intercalated within a first polyolefin. The second layer directly contacts a surface of the first layer and includes a first thermoplastic resin. The third layer directly contacts a second surface of the first layer and includes a second thermoplastic resin. The first thermoplastic resin and second thermoplastic resin can be the same or different.

  • Publication number: 20120128988
    Abstract: An insulation sheet for electric machine that forms slot insulation sheet is configured by an aramid paper and a PPS film directly pressure laminated without use of an adhesive. This means that no adhesive layer interposes the aramid paper and PPS film. PPS film is less costly as compared to a polyimide film and possesses better thermal properties such as higher heat emissivity and is highly resistant to heat. Thus, high strength is maintained even when subjected to high temperature over extensive time. Further, because the aramid paper and PPS film are laminated directly without an adhesive layer, the laminate is reduced in thickness. This allows further thinning of the laminate.
