INNERSEAL THAT CAN BE APPLIED BY MICROWAVE ENERGY

摘要

Innerseal comprising a heat-sealable layer, wherein heating by microwave energy is employed to soften the heat-sealable layer, thereby allowing it to be bonded to the lip of a container. Innerseals of this invention require a layer of polymeric material capable of being heat-sealed to the lip of a container and a layer formed of material capable of absorbing microwave energy, converting that energy to heat, and transferring that energy, either directly or indirectly, to the layer of heat-sealable polymeric material.
