A polyvinylidene fluoride film composition and a polyvinylidene fluoride isolation film are provided. The polyvinylidene fluoride film composition includes a polyvinylidene fluoride, a polyetherimide, and a polyether-type nonionic surfactant. The weight ratio of the polyvinylidene fluoride to the polyetherimide is 1:1 to 19:1, and the content of the polyether-type nonionic surfactant is 0.1% to 10% by weight based on a total of 100% by weight of the polyvinylidene fluoride film composition.
