To improve the poor oxidation resistance of traditional PET medicine bottles, the invention provides a preparation method of anti-oxidant medicine bottles. Firstly, polyethylene terephthalate is modified with aromatic compounds, then processed into masterbatches by an extruder. Finally, the modified PET polymer masterbatches are fabricated into medicine bottles via blow molding technology. The anti-oxidant medicine bottles prepared by this method feature excellent oxidation resistance and high temperature resistance, effectively extending the storage shelf life of medicines.
