The invention belongs to the field of composite material production and preparation, and relates to a fiber reinforced thermoplastic resin unidirectional prepreg tape and a preparation method thereof. The prepreg tape is prepared from the following components, by weight: 30-70 parts of a thermoplastic resin, 30-70 parts of nature fibers, 0-1 part of a coupling agent, and 0-1 part of an emulsion. Compared with the prepreg tape in the prior art, the prepared nature fiber/thermoplastic resin unidirectional prepreg tape of the present invention has the following advantages and beneficial effects that: mechanical strength is high, the prepreg tape can be stored for a long time, the nature fibers are completely impregnated by the resin and are not exposed to the outside so as to maintain the dry state of the material, particularly the nature fibers, the nature fibers are not easily subjected to mildew deterioration, and the porosity is low so as to ensure performance stability of the product. With the method, the w
