Will my produce stay fresh in these bags?

Most vegetable will do fine just as they are in the bag in your refrigerator. Wrap leafy greens, such as lettuce, in a damp towel as these vegetables tend to dry out quickly. Fruit such as apples and pears will benefit from the mesh material that allows the ethylene gas that these fruits release to escape, thus helping to preserve the fruit. The bag has no chemicals in it that will preserve produce.
