Recycled Polymer Composition for Manufacturing Small to Medium-Sized Container Including HDPE Recovered from Secondary Battery Separator and Small to Medium-Sized Container Manufactured Therefrom

A polymer composition for manufacturing a small to medium-sized container and which includes a high-density polyethylene (HDPE) recovered from a secondary battery separator. A polymer composition having excellent processability may be prepared by recycling a secondary battery separator. The polymer composition may be molded to manufacture an environmentally friendly small to medium-sized container, such as a small to medium-sized container, having excellent flexural strength, elongation, impact strength, and environmental stress crack resistance.
