The air-tight bag will prevent air from entering into the bag and without air, there will be fewer bacteria growth so it will last longer. Most bacteria cannot survive in a vacuum; they need air for growth. So, it is good to store it in an airtight bag.

We can make it last longer by wrapping it on a separate paper towel before placing it in a zip-top bag and then into the refrigerator. It will last up to 7-days which is enough for a vegetable. Most bacteria grow at room temperature. They need a temperature near to the room (25°C) for growth and storing it in the refrigerator will decrease its temperature and ultimately it will last longer.
