Disclosed is a packaging for a flexible secondary battery comprising a first polymer resin layer, a barrier layer formed on the first polymer resin layer to block water and gas, and a second polymer resin layer formed on the barrier layer. The thickness of the barrier layer is 30 to 999 nm. The barrier layer is multi-layered, and comprises graphene, a dispersing agent, and pyrene as a flexible linking agent, in which there is π-π conjugation (interaction) between the graphene and the pyrene. Also disclosed is a flexible secondary battery comprising the packaging.
