    Abstract: The present invention relates to a multilayer film comprising at least two outer layers and at least one core layer, at least one of the outer layers comprises component a1), the other outer layer comprises component a1) or a2). Component a1) is a terpolymer of propylene, ethylene and one C4 to C10 α-olefin; having ethylene content in the range of 0.1 to 8.0 wt.-%, C4 to C10 α-olefin content in the range of 0.1 to 16.0 wt.-%, and a melt flow rate MFR2 0.5 to 12.0 g/10 min. Component a2) is a polypropylene having a melting temperature of at least 150° C. The core layer comprises a heterophasic propylene copolymer b) having MFR2 of 0.3 to 20.0 g/10 min, XCS content of 16.0 to 50.0 wt.-%, and comonomer content of 11.5 to 21.0 mol-%, comprising a matrix being a random propylene copolymer b1) and an elastomeric propylene copolymer b2) dispersed in said matrix.

    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.
