Ask HN: How to keep Fruits and Vegetable fresh (actual and perceived) until delivery

Hey All, When Fruits & Vegetables have to be shipped from warehouse to a customer's house (transport time - 5-10 hours). What kind of packaging can we use for fruits & vegetables to ensure the freshness - actual & perceived till it reaches customer's house? Constraint - we cannot have cold room in the transportation vehicle due to high cost per order. Thanks
