The invention relates to a manufacturing method of a high-strength type reflection film. The manufacturing method of the high-strength type reflection film includes the following steps: step a, a bonding layer is coated on the surface of a first vase material; step b, a bead establishing layer is formed on the surface of a second base material with pressure-sensitive adhesive, and a reflection layer is plated on the surface of the outer side of glass beads of the bead establishing layer; step c, a light reflecting layer formed by the bonding layer, the reflection layer and the glass beads is formed; step d, embossing is carried out on the back face of the bonding layer through a hot-press embossing roller, and therefore partial of the bonding layer is pressed to form square protruded ribs, and transparent surface material is connected with tops of the protruded ribs; step e, after the bonding layer is embossed, a supporting layer is sprayed on the back of the bonding layer so as to form a plane; and step f, the pressure-sensitive adhesive is evenly coated on the back of the supporting layer, and release materials are covered on the pressure-sensitive adhesive. According to the manufacturing method of the high-strength type reflection film, the smooth supporting layer can be acquired, coating of the pressure-sensitive adhesive can be smooth and uniform, bonding effect is good, and sizing material can be saved.
