NO, After activating the BerryBreeze™ unit your refrigerator transforms to an almost perfect environment. Therefore, there is no need for plastic bags or containers when storing your fresh produce. Actually, we prefer that you either place your produce in the appropriate bins and store them in their native or natural state.
*However, leafy vegetables such as Kale, Spinach, and Lettuce are high moisture vegetables and therefore benefit more from humid environments such as your vegetable bin/crisper. If your refrigerator is not equipped with a vegetable bin/crisper then we suggest you place your leafy vegetables in a plastic bag (with holes) or covered with a moist paper towel. You may also mist as needed.
