  • Patent number: 10781303
    Abstract: High flow nucleated heterophasic polyolefin compositions comprising a matrix comprising a propylene homo- and/or copolymer and an elastomeric alpha-olefin copolymer phase dispersed in the matrix, which have rather high melt flow rate, improved impact strength but also an excellent impact/stiffness balance and a process for the preparation of such a heterophasic polyolefin composition, articles made therefrom and uses of the heterophasic polyolefin composition.
    Type: Grant
    Filed: March 1, 2017
    Date of Patent: September 22, 2020
    Assignee: BOREALIS AG
    Inventors: Claudia Kniesel, Minna Aarnio-Winterhof, Karlheinz Friedrich, Markus Gahleitner, Friedrich Berger
  • Patent number: 10781304
    Abstract: Polypropylene composition comprising (A) 60 to 95 wt % of a heterophasic polypropylene (HECO) comprising 10 to 30 wt % of dispersed phase with the dispersed phase having a comonomer content of 30 to 45 wt % and the HECO having a melt flow rate MFRPP in the range of 12 to 200 g/10 min and being prepared in the presence of a Ziegler Natta catalyst (ZN-C), (B) 0 to 15 wt % of one or more elastomers, (C) 5 to 20 wt % of at least one filler wherein the polypropylene composition fulfils inequation (1) fogging?0.02 MFRComp+0.3. The composition allows for a well-balanced combination of a good impact/stiffness balance, a good scratch resistance, low VOC and FOG emissions and remarkable good fogging values.

  • Patent number: 10351284
    Abstract: A process for collation shrink wrapping an object that may include a number of individual containers, preferably a number of substantially identical containers. The process may include the steps of (i) obtaining a binding tape that is a film uniaxially oriented in the machine direction (MD) and wrapping the tape around the object, (ii) sealing the ends of the now wrapped binding tape (i.e., to form a loop), (iii) obtaining a collation shrink film that may include a multimodal linear low density polyethylene (LLDPE), the film being a stretched film that is uniaxially oriented in the machine direction (MD) in a draw ratio of at least 1:3, (iv) wrapping the collation shrink film around the object of step (ii), (v) heating the wrapped object of step (iv) such that the tape shrinks in its machine direction and the collation shrink film shrinks in its machine direction.
