Abstract
A high-barrier liner for a composite container that is compatible with the use of RFID devices in the container includes a paper layer having an outer surface for attachment to an inner paperboard surface of a body wall of the container, and a metallized film attached to the inner surface of the paper layer, the metallized film comprising a polymer film substrate having a vapor-deposited layer of metal applied to one surface of the substrate. The liner also includes a heat seal layer disposed on an opposite side of the metallized film from the paper layer and forming an innermost surface of the liner. The metallized film can include a metallization-promoting material coated onto the substrate prior to metallization to improve the uniformity and continuity of the metal layer. The metal layer of the metallized film can have a protective coating applied over it.
