Abstract: An object of the present disclosure is to provide a composition for preventing or treating obesity comprising a substance isolated from poly-?-glutamic acid (?-PGA) as an active ingredient. According to the present disclosure, it was confirmed that ?-PGAbm or ?-PGAcm, a substance isolated from ?-PGA, suppressed the expression of adipogenic marker genes in 3T3-L1 cells to reduce accumulation of lipid droplets and triglycerides, and suppressed the expression of cell cycle regulators in the early stage of adipogenesis to reduce adipocyte differentiation. In addition, ?-PGAbm or ?-PGAcm has been confirmed to suppress obesity through weight loss, positive changes in glucose and insulin resistance, reduction of epididymal adipocytes, and suppression of adipogenesis, and thus may be used effectively for related businesses.

Abstract: The present invention relates to a one-touch-removable container packaging film, and a container comprising same and, more specifically, to a one-touch-removable container packaging film, and a container comprising same, the packaging film: being naturally removable from the container when a container lid is rotatably separated from a container body in order to open contents sealed in the container, so as to be forcibly removed from the container according to the opening of the container contents without the need to consciously remove the packaging film in order to recycle the used container, and thus inconvenient actions such as removal of the packaging film during disposal of the container can be fundamentally eliminated; being forcibly removable according to the opening of the container contents so that the packaging film is necessarily removed from the container after the container is used even if the packaging film is not intended to be removed; and being easily removable with only a one-touch rotational
