1. Before Use: Before using an ice pack, ensure it is completely frozen for optimal cooling. Also, check the ice pack for any damage or leaks.
2. During Use: Place the items to be refrigerated into the ice pack, removing as much air as possible to reduce heat conduction. Then seal the ice pack to prevent cold air loss and the entry of external heat sources.
3. After Use: After use, promptly remove the ice pack from the freezer and store it properly. Do not refreeze melted ice packs, as this may damage the material and structure.
4. Maintenance: Regularly clean the inside and outside of the ice pack to maintain hygiene. Avoid placing the ice pack in high-temperature environments to prevent material deformation and failure. Additionally, periodically check the seal of the ice pack; replace it immediately if damaged.
