The present invention relates to an improved laminate for containers of liquid, such as juice, the laminate comprising: a paperboard substrate; an outer layer of a member selected from the group consisting of heat-sealable low density polyethylene polymers and Plexar; and an inner barrier layer of a polymeric nanocomposite blend comprising at least one resin and a layered silicate dispersed in said resin. The layered silicate preferably has a layer thickness of about 7 to 12 A and an interlayer thickness of about 30 A or greater. |
