The action mechanism of the plasticizer includes inserting into the polymer chain to reduce the stress of the polymer chain, reduce the fluidity of the polymer chain, reduce the crystallinity of the polymer, and improve the plasticity of the polymer material. When plastic bags are added to polymers, the interaction among plastic bags, plastic components and polymer fluids is important. Due to the high flexibility of false eyelashes, a suitable plasticizer is needed to adjust the binding agent for eyelashes. Dimethyl phthalate, dioctyl phthalate and polyethylene glycol were used in the experiment.<br>
