Abstract： Agar， as a natural polysaccharide， has broad application prospects in the field of food packaging becauseof its good gel，film formingand biodegradability.This article provides asystematic overviewof the sources， chemical structures，and physicochemical properties of agar. It elaborates on the clasification and performance advantages of agar based biodegradable food packaging films，and summarizes their specific applications in the preservation of meat，fruits，vegetables，dairy products，and other foods.Theaimis to provide theoretical references for the innovative development of food packaging materials.

Keywords： agar; degradable films; food packaging; food preservation

近年來，塑料污染已成為全球性環(huán)境問題，傳統(tǒng)塑料包裝因其不可降解性，在自然環(huán)境中長期積累，進而產(chǎn)生許多負面影響，如釋放雙酚A、鄰苯二甲酸鹽等有害化學物質(zhì)，對生態(tài)系統(tǒng)和人類健康構(gòu)成嚴重威脅[1]。（剩余7581字）
