A packing bag containing scallion and garlic is to put the contents of scallion and garlic plants into the holding space of the packing bag and seal them. When the contents consume oxygen under the action of respiration and continuously generate carbon dioxide to fill the holding space, the oxygen content in the holding space is relatively reduced, and when the air pressure inside the holding space is greater than that outside the packing bag due to the full of carbon dioxide, the content is over oxidized Carbon can be discharged out of the packaging bag by a one-way vent valve, thereby forming the creation.一種含有蔥蒜之包裝袋,係將蔥蒜類植物之內容物放入包裝袋之容置空間內且密封,待內容物在呼吸作用下耗氧且不斷生成二氧化碳充滿在容置空間內,令容置空間內的含氧量相對減少,且當容置空間內因充滿二氧化碳而氣壓大於包裝袋外的氣壓時,過飽之二氧化碳可由單向透氣閥排出包裝袋外,藉此構成本創作。
