The present invention relates to a production method of an acrylic film, which is produced by a solvent casting method from a dope comprising an acrylic resin composition in which a low molecular weight acrylic resin is mixed with a high molecular weight acrylic resin, and has improved modulus while securing dope viscosity and discharge processability. 본 발명은 고분자 아크릴 수지에 저분자 아크릴 수지를 혼합한 아크릴 수지 조성물을 포함하는 도프로부터 Solvent casting 방식으로 제조되고, 도프 점도 및 토출 공정성을 확보하면서도 모듈러스가 개선된 아크릴 필름의 제조방법에 관한 것이다.
