PURPOSE: A multi-layer film for yacht anchor is provided to have high durability and weather resistance by using polyethylene terephthalate and UV blocking particle, and be economical and has superior property of matter of film. CONSTITUTION: The multi-layer film for yacht anchor includes a base layer and a surface layer. The base layer contains the poly ethylene naphthalate in which the inherent viscosity is 0.4 ~ 1.0 dL / g, and the mixture of the polyethylene terephthalate / polyethylene naphthalate copolymer or the polyethylene terephthalate and poly ethylene naphthalate. The surface layer is laminated on one side of both sides of the base layer and contains the polyethylene terephthalate, in which the inherent viscosity is 0.6 ~ 1.0 dL / g, and the UV blocking particle.
