Abstract: A fresh-keeping bag is provided with a zipper assembly including a slider and a zipper. The slider comprises two limiting pieces arranged in parallel and each provided with two limiting blocks, one connecting block, and an opening tongue located between the two limiting pieces and connected with the connecting block. The zipper comprises two single-chains, each provided with two toothless hooks arranged in parallel and respectively arranged on the two single-chains to cooperate with each other one to one; one of the two toothless hooks on each single-chain is provided with an auxiliary track on one side thereof; and the auxiliary tracks respectively arranged on the two single-chains are disposed oppositely The opening tongue props open the toothless hooks indirectly, eliminating the possibility of moisture flowing out between the opening tongue and the toothless hooks. Fresh-keeping bags applied with such zipper assembly prevent moisture from flowing out from the opening.
