ABSTRACT:
An ultrasonically bonded microwave susceptor material and method for manufacturing this microwave susceptor material. A laminated microwave susceptor material has first and second plies of material ultrasonically bonded together over a part of an area thereof. The first ply of material is a layer of thermally fusible plastic such as a thermoplastic polyester, the second ply of material is a layer of paper or paperboard and at least one of the first and second plies of material includes a microwave interactive material capable of converting microwave energy to thermal energy. The microwave interactive material may consist of a metallized surface on the plastic layer or the paper, and in such cases the metal layer may be arranged between the plastic layer and the paper. The first and second plies of material are ultrasonically bonded along a multiplicity of bonding lines or rows of bonding spots. In this process, the heat fusible plastic is melted and resolidified to secure the first ply to the second ply. In some cases, bonding of the plies is obtained by a localized piercing or degrading of the metal coating that enables formation of a plastic-paper interface.
