The invention relates to a high-content polylactic acid transparent oil bottle, which belongs to the field of macromolecular materials. The high-content polylactic acid transparent oil bottle is prepared from the following raw materials in parts by weight: 90 to 98 parts of polylactic acid, 1 to 10 parts of flexibilizer, and 1 to 5 parts of shock-resistant modifier. The preparation method comprises the following steps: granulating the raw materials by virtue of a dual-screw extruder, drying, injection molding by virtue of an injection molding machine, and blow molding by virtue of a blow molding machine to obtain a finished product. The high-content polylactic acid transparent oil bottle has the advantages that by virtue of the blending and modification of the polylactic acid, on the premise of ensuring the transparency of the product, the weaknesses of high brittleness, low transparency and poor shock strength can be overcome, so that the polylactic acid bottle is suitable for holding edible oil, and the food safety can be ensured.
