The key to keeping ice packs last longer is to keep them cold. Here are some suggestions:
1.Cryogenic storage: Keep the ice pack in the refrigerator or freezer to make sure it is kept cold. It is advisable to place the ice pack in a well-sealed plastic bag or container to prevent the ice from melting and maintain its freshness.
2.Avoid re-freezing: Once the ice pack has been frozen, do not freeze it again. This is because repeated freezing can destroy the structure of the ice pack and reduce its thermal insulation performance.
3.Moisture-proof treatment: Ice packs are prone to moisture absorption, which will lead to a decrease in their thermal insulation performance. Therefore, it is advisable to keep the ice pack in a dry place and avoid contact with wet items.
4.Regular Inspections: Regularly check the thermal insulation performance of the ice pack to ensure that it is kept in good condition. If you find that the insulation performance of the ice pack is decreasing, you can try to dry it in the sun or use other methods to fix it.
5.Pay attention to the expiration date: The shelf life of the ice pack is usually 1-2 years. If the expiration date has passed, it is recommended to replace the ice pack with a new one to ensure that it maintains good thermal insulation properties.
6.Avoid violent vibrations: During transportation or use, avoid severe vibration or impact on the ice pack, which may damage the structure of the ice pack and reduce its thermal insulation performance.
In conclusion, in order to make the preservation effect of ice packs last longer, we should pay attention to keeping them cold, avoiding repeated freezing, moisture-proof treatment, regular inspection, paying attention to the expiration date, and avoiding violent vibrations. These measures can help us extend the life of the ice packs and maintain good thermal insulation performance. Autumn and Winter Check-in Challenge
