Keep-It Fresh Produce Bags naturally slow down the normal ripening process to keep foods and flowers fresh longer! After harvesting, most fruits, vegetables and flowers, release certain gasses that cause them to ripen and then rot, in a short period of time. Keep-It Fresh Produce Bags are designed to absorb and remove these gasses away from the produce, extending the freshness period and helping to maintain the nutritional value. Great for: Bananas, strawberries, grapefruit, grapes, oranges, apples, peaches, berries, cherries, kiwi, tomatoes, lettuce, cucumbers, avocados, asparagus, carrots, fresh cut flowers, fresh herbs, and much, much more!
