Beschreibung
Zusammenfassung:	In the present specification, disclosed is an electromagnetic wave shielding film which comprises: an electromagnetic wave shielding layer which is disposed between an insulating layer and a conductive adhesive layer and which has at least two metal sheet layers; and a polymer resin adhesive layer which contains metal powder and which is disposed between the metal sheet layers. The film has an excellent electromagnetic wave shielding effect since at least two metal sheet layers are electrically connected to each other through metal powder, and has excellent resistance to breakage or cracking when repeatedly folded, due to the flexibility of a polymer resin, compared to a film containing a single metal sheet layer. 본 명세서는 절연층과 전도성 접착층 사이에 2개 이상의 금속 시트층을 전자파 차폐층을 포함하되, 상기 금속 시트층 간에 금속 분말을 포함하는 고분자 수지 접착제층을 포함하는 전자파 차폐 필름을 개시한다. 상기 필름은 2개 이상의 금속 시트층들이 서로 금속분말들을 통해 전기적으로 연결되어 전자파 차폐효과가 우수하며, 고분자 수지의 유연성(Flexibility)으로 단일층의 금속 시트층을 포함하는 필름보다 반복접힘시 끊어짐 또는 크랙 발생에 대한 저항성이 우수하다.
