    摘要： The present disclosure relates to a packaging for a cable-type secondary battery, surrounding an electrode assembly in the cable-type secondary battery, the packaging having a moisture-blocking layer comprising sealant polymer layers on both outer surfaces of a moisture-blocking film and a moisture-blocking film disposed between the sealant polymer layers, wherein the moisture-blocking layer is a tube form surrounding the electrode assembly, and the sealant polymer layers in both ends of the moisture-blocking layer are overlapped and adhered with each other in a predetermined part. The packaging according to the present disclosure can be used in a cable-type secondary battery to block moisture from being infiltrated into an electrode assembly, thereby improving the life characteristics of the battery and preventing the deterioration of battery performances.
