Abstract
A packaging material comprising a substrate and a liner extending along the substrate. The liner comprises at least a biopolymer and graphene nanoplatelets to provide a gas barrier along at least a portion of the packaging material.
Claims14
A packaging material, comprising:
- a substrate;
- and
- a liner extending along the substrate, the liner comprises at least a biopolymer and graphene nanoplatelets to provide a gas barrier along at least a portion of the packaging material, wherein the graphene nanoplatelets are randomly dispersed in the biopolymer so that agglomeration of the nanoplatelets is avoided.
