The invention discloses a production method of a TPU film for exhaust type laminated glass. The production method is characterized by comprising the following steps: S1, putting a pre-prepared PE release film with lines on the surface into a silica gel matte roller; s2, putting an aliphatic TPU raw material into a blanking hopper of a casting machine, feeding the aliphatic TPU raw material into a screw rod, extruding the aliphatic TPU raw material from a die head to form a thin film, and feeding the thin film between a silica gel matte roller and an iron embossing roller; s3, the silica gel matte roller and the iron embossing roller are controlled to work, the aliphatic TPU film formed by the die head is attached to the face, with the lines, of the PE release film, the lines on the two faces are pressed out, and then the PE release film is wound through a winding machine. By designing the exhaust lines on the TPU surface, gas in the glass lamination process is easy to exhaust, the finally produced glass is cl
