Thermos Freezing Board 400G (3 Pack)

The duration the boards stay cold depends on factors like the ambient temperature, the effectiveness of the insulated container, and how frequently the container is opened. They are designed to help maintain cold temperatures for several hours, typically longer for packed lunches than for extended outdoor trips.

It is recommended to place the freezing boards in contact with the packaging of food items or within the container, rather than directly on exposed food, to prevent potential moisture or damage from extreme cold.

Wipe them clean with a damp cloth and mild soap if necessary. Rinse well and ensure they are completely dry before placing them back in the freezer.

Yes, they are designed for use with food in insulated containers. Ensure they are clean before each use and handle them carefully to avoid damage.

If a freezing board is punctured, it may leak its contents. Discontinue use immediately to prevent contamination and avoid further damage.

The number of boards to use depends on the size of your insulated container and the desired cooling duration. For a standard lunch box, one or two may suffice. For larger cooler bags, you might use three or more.

Yes, these are reusable freezing boards and are designed to be refrozen and used repeatedly for cooling.

Ensure the board has been in the freezer for adequate time (at least 8-12 hours) and that your freezer is set to an appropriate temperature.

Inspect the board for any punctures or damage. If a leak is detected, discontinue use to avoid contamination.

Check that the insulated container is properly sealed and not overfilled. Ensure the freezing board is fully frozen and has not been exposed to ambient temperatures for too long before use.
