    • The present invention provides a thermoplastic resin sheet and its molded article for a packaging material which is heated in a microwave oven and for shielding electromagnetic waves. The above-mentioned resin sheet and molded article are characterized by generating heat when irradiated with microwaves.
      The present invention is directed to an electroconductive thermoplastic resin sheet which is prepared by first superposing an electroconductive nonwoven fabric mainly comprising electroconductive fibers and heat-meltable fibers upon one surface, both the surfaces, or a part or all of the surface of a thermoplastic resin film as a base material layer, further superposing a thermoplastic resin film as a protective layer upon the nonwoven fabric so that they may come in contact with each other, heating and contact-­bonding them at a temperature of the melting point or higher of the heat-meltable fibers, and it is also directed to an electroconductive thermoplastic resin-­molded article which is prepared by heating the aforesaid electroconductive thermoplastic resin sheet up to a temperature at which the resin sheet softens, setting the resin sheet between a pair of female and male molds the surface of at least one of which comprises a heat-­ resistant rubber, and then mating both the molds to mold the resin sheet.
    • 本发明提供一种热塑性树脂片及其用于包装材料的模塑制品,其在微波炉中被加热并用于屏蔽电磁波。 上述树脂片和模制品的特征在于当用微波照射时产生热量。 本发明涉及一种导电热塑性树脂片,其通过首先将主要包含导电纤维和可热熔纤维的导电无纺布叠加在热塑性树脂的一个表面,两个表面或一部分或全部表面上 膜作为基材层,进一步将热塑性树脂膜作为保护层叠加在无纺布上,使得它们可能彼此接触,在热的熔点或更高的温度下加热和接触它们 并且还涉及一种导电热塑性树脂模塑制品,其通过将上述导电热塑性树脂片材加热到树脂片软化的温度制备,将树脂片材设置在一对雌性和雄性之间 模制其中至少一个的表面包括耐热橡胶,然后配合两个模具t o模制树脂板。
