Abstract
An innerseal facing construction is disclosed which includes three layers. An induction heatable layer overlies a heat sink layer, which in turn overlies a bonding layer. The bonding layer has several strata of material of progressively higher melting points. The construction provides an innerseal facing that may be used over a broad range of induction power levels to provide progressively stronger bonding between the innerseal facing and the container.
