A film and a device for tearing film. The film includes a film body and a first protection film, and the first protection film includes a first magnetic part. Thus, the first protection film of the film can be torn off and removed by magnetic force, without contacting with the film by using adhesive tape, thereby avoiding a problem of failure of capturing the adhesive tape due to limited precision of the mechanical arm transmission, so that success rate of tearing film is improved and a problem of damaging the film body due to too large press force is avoided.
