| 摘要 |
An innerseal facing (10) construction is disclosed which includes three layers. An induction heatable layer (12) overlies a heat sink layer (14), which in turn overlies a bonding layer (16). The bonding layer has several strata (18, 20, 22) 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 a container (49). |
