The correct method of using insulation bags

1. Preheating before use: Soak the insulation bag in warm water to increase its temperature, which can better maintain the insulation effect.
2. Pay attention to packaging sealing: When using insulation bags, ensure that the packaging is sealed and do not leak air, otherwise it will greatly reduce the insulation effect.
3. Keep replenishing heat: When placing hot items inside the insulation bag, it is important to replenish heat in a timely manner, such as adding some hot water bags, insulation blankets, etc. to extend the insulation time.
4. Do not leave it for too long: If the item to be insulated needs to maintain a certain temperature for a long time, it is recommended not to leave it for too long to avoid safety hazards.
