    摘要： 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.

    摘要： 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.

    摘要： A process for collation shrink wrapping an object that may include a number of individual product containers, preferably substantially identical product containers. The process may include the steps of (i) 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, (ii) wrapping the object in the film, and (iii) heating the object wrapped in the film in order to collation shrink the film around the object.
