I live in Anchorage, Alaska and so my question deals with colder weather. I bought 2 Dwarf Alberta Spruce bushes that I want to plant in containers. Do I need to line the container with anything to prevent the roots from freezing in the winter? The containers I purchased to plant them in are plastic. Thank you for your help!

Anytime you live in Zones 5 or less, which is the case here, potted plants will need to come indoors. Even a garage or basement will work. Wrapping is not necessary for those brought inside. If you choose to wrap or insulate the pots and leave them outdoors, the likelihood of their surviving would be minimal at best.
