The invention discloses a method for synthesizing artificial leather for leather carving soft packaging. The method comprises the following steps: coating a base cloth with PVC paste resin; weighing all components of a surface layer in proportion, stirring the weighed components at 800-1000 rpm for 20-30 min, performing blade coating on the PVC paste resin coated base cloth, and drying the blade-coated base cloth in a 120-130 DEG C oven for 3-5 min to form the surface layer; weighing all components of a bottom layer in proportion, stirring the weighed components at 800-1000 rpm for 20-30 min,performing blade coating on the bottom of the surface layer with the stirred material to form a layer, and drying the blade-coated surface layer in the 120-130 DEG C oven for 3-5 min to obtain a prefoamed composite layer; and foaming the prefoamed composite layer to obtain the artificial leather. Semi-drying treatment makes a part of a solvent volatilize before application, so damages of the solvent to the surface layer o
