Abstract: 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.

Abstract: Provided are multilayer polymer films comprising LLDPE, LDPE and a random propylene-ethylene copolymer which films suitable for packaging applications and are mechanically recyclable, and to recycled polymer compositions formed by mechanically recycling such films. The recycled polymer compositions may be combined with a polypropylene random copolymer and used to form further polymer films suitable for packaging applications applications.

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.
