    Abstract: This invention relates to articles capable of being heated by magnetically coupled radio frequency energy. Bonding by induction heating can be used to seal bags and pouches, seal window panes, bind books, and the like. Induction heating can be used in situations where microwave heating is not suitable, such as, for example, in cases where the materials to be bonded absorb microwave energy, such as polar polymers, wood, or materials containing non-magnetic conductive particles. In these situations, it may be desirable to heat the bond area only and not the material to be bonded. This invention provides a composition comprising: (1) a susceptor of magnetically coupled radio frequency energy comprising a non-magnetic particulate substrate, e.g., an electrically insulative material in particulate form, bearing a thin magnetic coating, e.g., a magnetic inorganic film, and (2) a matrix that is substantially non-reflective of radio frequency energy, e.g., silicone rubber, which matrix can be heated upon the composition's being subjected to magnetically coupled radio frequency energy. It has been discovered that thin magnetic coatings on non-magnetic particles provide energy transfer with induction heaters equal to or better than many commonly used solid susceptor particles. It has also been discovered that the temperature of the composition of this invention can be regulated so as not to exceed a predetermined temperature.

    Abstract translation: 本发明涉及能够通过磁耦合射频能量加热的制品。 通过感应加热粘合可用于密封袋和袋，密封窗玻璃，装订书等。 感应加热可用于微波加热不适合的情况，例如在待接合的材料吸收微波能量的情况下，例如极性聚合物，木材或含有非磁性导电颗粒的材料。 在这些情况下，可能需要仅加热粘合区域而不是加热待结合的材料。 本发明提供了一种组合物，其包括：（1）磁耦合射频能量的感受体，其包含非磁性颗粒基质，例如颗粒形式的电绝缘材料，承载薄磁性涂层，例如磁性无机膜，和 （2）基本上不反射射频能量的基体，例如硅橡胶，该基质可以在组合物经受磁耦合射频能量时被加热。 已经发现，非磁性颗粒上的薄磁性涂层提供等于或优于许多常用固体感受体颗粒的感应加热器的能量传递。 还已经发现本发明组合物的温度可以调节到不超过预定温度。

    Abstract: There is herein disclosed a multi-layer structure which can suitably be used to manufacture a container in which sealing properties are improved for the prevention of container breakage during sterilization by heating, cooking by heating, distribution or the like and heat resistance is improved for the prevention of container deterioration and which is excellent in opening properties; and a container having the above-mentioned excellent characteristics which comprises this multi-layer structure. According to the present invention, there are provided a multi-layer structure having two or more layers which comprises a surface layer (a) comprising a thermoplastic resin and having a thickness of 10 to 80 µm and an adjacent layer (b) comprising a thermoplastic resin or a thermoplastic resin containing an inorganic filler, an interlaminar peeling strength between the surface layer (a) and the adjacent layer (b) being in the range of 0.3 to 2.0 kg/15 mm; and a container comprising this multi-layer structure.
