The invention relates to a formula of a soft capsule shell, which comprises gelatin, water, glycerol and sorbitol. The formula is characterized in that the proportion of a plasticizer (namely glycerol) and sorbitol is adjusted, and the components are as follows by weight percentage: gelatin 80-100%, water 60-80%, plasticizer 40-60%, antioxidant 0.2-1.2%, and PEG-400 (polyethylene glycol-400) 5-15%. Due to high requirements of soft capsules for the plasticity of shell materials, the moisturizing property of sorbitol is considered and the shell is ensured not to cause softening, deformation, adhesion, liquid leakage and other problems of the soft capsule due to excessive water content, so that the plasticizer is mixed for use to ensure the stability of the capsule. The antioxidant can prevent crosslinking due to oxidation reactions among the substances in the shell material, so as to cause time delay in disintegration of the soft capsule. The addition of the antioxidant in the formula provided ...
