A biodegradable thin film material and a manufacturing method thereof include: a biodegradable material consisting of any one or more of PLA, PBAT, and PBS, with a content of 60 to 70 mass percent; a food-grade agricultural waste It is starch, fiber, protein or lipid with a particle size of at least 50 μm and a content of 10-30% by mass. A quality modifier can be calcium carbonate (CaCO 3 ) powder or magnesium silicate powder. The quality modifier has a particle size of at least 8 μm and a content of 7 to 29 mass percent; and an organic decomposing strain is a heat-resistant liquefied bacillus amyloliquefaciens with a content of 1 to 3 mass percent; the aforementioned biodegradable material, food-grade agriculture After the waste, quality modifier and organic decomposing bacteria are kneaded in the process, they are blown into a biodegradable film with a film thickness of 40μm ~ 60μm. |
