Embodiments of the subject invention relate to a method and apparatus for thermally protecting a product, such as when storing and/or shipping a product, so as to control the temperatures the products are exposed to. Embodiments can increased the amount of time the product and/or portions of the product experience a desired temperature range and/or reduce the amount of time the product and/or portions of the product experience temperatures outside of the desired temperature range and/or experience an undesirable temperature range. Embodiments can incorporate thermally conductive materials, such as aluminum sheets, positioned around and/or near the product positioned inside a packaging container, such that the conductive materials conduct heat from one or more locations in the interior of the package to one or more other locations in the interior of the package. These thermally conductive materials can be referred to as conductive equalizers. The conductive equalizers can conductively transfer heat from the hotter portions of the interior of the container to cooler portions of the interior of the container and/or from portions of the interior desired to be cooled to the cold bank. Conducting heat from hotter portions to cooler portions, or from portions to be cooled to the cold bank can result in a more uniform temperature distribution around the product.
