The invention discloses a moldable two-way stretch polypropylene film as well as a preparation method and application thereof. The moldable two-way stretch polypropylene film comprises a first moldable layer, a second moldable layer, a polypropylene core layer and a polypropylene surface layer; the moldable two-way stretch polypropylene film is prepared by the first moldable layer, the second moldable layer, the polypropylene core layer and the polypropylene surface layer through a coextrusion two-way stretch process. Compared with a traditional moldable two-way stretch polypropylene film, themoldable two-way stretch polypropylene film has the advantages that the appearance is good, surface scalding cannot be generated in film preparation and laser mold pressing processes, the film preparation and mold pressing speed is higher, the film heat shrinkage is lower, and the thickness uniformity is higher.
