Title:
BIODEGRADABLE RESIN COMPOSITION, AND BIODEGRADABLE FILM AND BIODEGRADABLE PRODUCT USING SAME
Document Type and Number:
WIPO Patent Application WO/2023/008902
Kind Code:
A1
Abstract:
The present invention relates to a biodegradable resin composition including a polyhydroxyalkanoate (PHA) resin and a polybutyleneadipate terephthalate (PBAT) resin. The biodegradable resin composition, which includes, based on the total weight of the biodegradable resin composition, 40 wt% to 99 wt% of the PHA resin and 1 wt% to 60 wt% of the PBAT resin, and a biodegradable film and a biodegradable product that use same are provided. By having the specific compositions, the biodegradable resin composition according to an embodiment may be able to improve the mechanical characteristics and optical characteristics of a biodegradable film formed therefrom simultaneously, may enable biodegradation both in the soil and the ocean, and thus may exhibit excellent characteristics when applied to more diverse fields.
