The invention provides a bag skin material and an aerostat. The bag skin material comprises a weather-proof layer, an air-blocking layer, a weight-bearing layer and a welding layer which are overlapped, wherein the air-blocking layer is organic polymer with montmorillonite dispersed. The montmorillonite is dispersed in the organic polymer to form the air-blocking layer. Due to the property that the montmorillonite is layered crystalline silicate clay ore, the air-blocking performance of the bag skin material is improved. Furthermore, leakage of air inside the aerostat or an airship is reduced, and the hang time of the aerostat or the airship is lengthened.
