  • Patent number: 11865818
    Abstract: The present invention deals with a multilayer structure comprising a first polyethylene layer as a first external layer. The first polyethylene layer is oriented in at least machine direction. The structure also comprises a second polyethylene layer as a second external layer. It further comprises a layer made of a copolymer of ethylene and vinyl alcohol (EVOH) between the first external layer and the second external layer and a tie layer on each side EVOH layer. Furthermore, the tie layers comprise one or more copolymers of ethylene.

  • Patent number: 10287074
    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.
