This invention relates to a full degradable bio-Films and producing method, including 5%~80% of high-density soil (such as Illite, Silica, Montmorillonite, Quartz, Mica, and etc.) composition or extract, 5%~50% biomass starch and 15%~45% toughening agent. With the effective use of the high proportion of inorganic, it can be directly modify as nutrients for the soil by spontaneous decomposition. After long-term use can increase the survival rate of crops and concurrently with breathable, waterproof, weather-resistant, easy to store and low price of characteristics.本發明係有關一種全降解生質薄膜及其製造方法,係由重量百分比5%~80%之高密度土壤、重量百分比5%~50%之生質澱粉及重量百分比15%~45%之增韌劑所組成,同時藉由高比例之無機物之有效利用,於自然環境分解後更可直接作為土壤改質的養分,長久持續使用後將能夠增加農作物的育成率,該薄膜製成品並兼具有透氣、防水、耐天候、易保存、價格低之特點。
