AI Technical Summary

Technical Problem

Existing nail polish bottles need to be bonded with a light-shielding material layer after blow molding, which is time-consuming and labor-intensive, and it is difficult to ensure both aesthetics and strength.

Method used

The nail polish bottle adopts a three-layer structure, with the inner layer being a PE containing layer, the middle being an adhesive connecting layer (such as Eva, epoxy resin glue or Evoh), and the outer layer being a decorative layer. The three layers of materials are stacked and blow-molded, avoiding the step of separately gluing the light-shielding layer, thereby improving the aesthetics and overall strength.

Benefits of technology

The production process is simplified, time and labor are saved, and at the same time, the light-proof storage of the nail polish and the strength of the bottle are ensured, thereby improving the aesthetics.
