The correct answer to this question is A, insulated. This type of packaging is not only used to ship food, but also to ship medicine, organs, blood, and chemicals. Insulated containers help keep the product fresh and efficient. Insulated containers can be constructed many different ways, including a vacuum flash, thermal blankets, and bubble wrap. The containers may also include block or dry ice, ice packs, or thermal mass.
Temperature loggers are also included to help monitor the temperature. Originally, insulated containers were single use, but aware of the environmental impact, reusable containers have been created, which have reduced waste by 95%.
