1. Use the foam box: put the blueberries in the foam box and fill enough ice around them to keep them fresh. Ice cubes can effectively prolong the fresh-keeping time of blueberries, but enough ice cubes should be ensured during transportation.
2. Multi-wrapping adhesive tape: wrap adhesive tape outside the foam box to increase the sealing performance of the package and prevent collision and extrusion during transportation.
3. Choose a fast courier service: Use a fast courier service, such as SF Express, to ensure that blueberries reach their destination in the shortest time.
4. Fill in the correct information: When mailing blueberries, you must fill in the correct recipient information, including name, address, telephone number and other necessary information to ensure that blueberries can be delivered to their destinations accurately.
5. Pay attention to the temperature: during transportation, ensure that the temperature of blueberries is kept below 5℃ to avoid blueberry deterioration. If the temperature is too high, blueberries will start to deteriorate and lose their freshness.
In a word, by using foam boxes, wrapping tapes, choosing express delivery service, filling in correct information and keeping the temperature, blueberries can be mailed better to ensure their freshness and integrity.
