Transparent breathable film for fresh-keeping packaging of agricultural products and manufacturing process thereof

The invention discloses a transparent breathable film for fresh-keeping packaging of agricultural products and a manufacturing process thereof. The manufacturing process comprise the steps that materials are selected from plastic film raw materials, transparent materials and auxiliaries. the materials are proportioned in equal proportion; stretching is carried out to form a film by using manufacturing steps of a film manufacturing machine; quality detection is carried out; and rolling and forming are carried out. Further disclosed is a using method. According to the method, a scheme which is high in performance, easy to process and low in price is provided in the aspects of material selection, proportion, dosage and mixing, the transparent breathable film produced through the method has good ductility and breathability, and the shelf life of agricultural products can be well prolonged; and the transparent breathable film can be naturally degraded. 一种用于农产品保鲜包装的透明透气膜及其制造工艺，包括材料选用塑料薄膜原料、透明材料、助剂；将材料进行等比例配比；使用制膜机的
