PURPOSE: A string for binding dried croakers and binding structure of dried croaker are provided to ensure a texture and a shape similar as binding structure of dried croaker with traditional straw even when using the poly propylene resin. CONSTITUTION: A poly propylene resin is first molded to a sheet form by using a molding machine. A folded part(10b) is formed by processing a first molded band(10a) to get folded mutually so that width can become narrow. A joint part(10c) of spiral shape is formed by heat-treating contacted parts to be jointed mutually while twisting folded parts into spiral shape along a drawing direction. It is preferable that an external diameter of string for binding dried croakers is about 3 to 7mm. |
