The invention relates to a three-dimensional (3D) toughened glass film and a forming process. The 3D toughened glass film comprises a glass substrate and a frame, the frame is glued to the edge of theglass substrate, and a containing cavity is defined by the frame and the glass substrate, wherein the frame is made of a plastic material. The forming process of the 3D toughened glass film specifically comprises the following steps: S1, determining a base material: concretely selecting glass with a thickness of 0.2-0.5 mm as the glass substrate, and determining the boundary dimension of the glass substrate; S2, carrying out polishing: concretely carrying out polishing treatment on the surface of the glass substrate to obtain a first semi-finished product; S3, carrying out surface tempering and cleaning: concretely carrying out surface tempering treatment on the first semi-finished product, and carrying out surface cleaning to obtain a second semi-finished product; S4, carrying out adhesive dispensing: concretely carrying out adhesive dispensing on the edges of the periphery of the second semi-finished product to form a colloid frame; and S5, carrying out forming: concretely processing the colloid frame to enable the inner side and the outer side of the colloid frame respectively to form an arch edge, so that a formed product is obtained. The frame in the 3D toughened glass film and the forming process is plastic made of an environment-friendly material, and the 3D toughened glass film has the advantages that the reject ratio is low, cost is low, screen print is convenient, and drop resistance is achieved.
