Abstract
A lidding film to use in food packaging, or the packaging of suitable non-food products, includes a substrate having an outer major surface on which is disposed at least a 5 heat-sealing layer (HS layer), a non-heat-sealing layer (NTIS layer), and a hydrophobic coating. On a side of the lidding film that corresponds to the outer major surface of the substrate is a peripheral region that encircles a central region. At least a first portion of the HS layer fills the peripheral region, and the NIS layer is absent as a cover on, or does not cover, the HIS layer in the peripheral region. At least a first portion of the NHS layer fills the 10 central region, and the HS layer is absent as a cover on, or does not cover, the NIS layer in the central region.
