Some embodiments of a cargo container door seal system can provide seal members to hinder leakage of conditioned air along the top edge and the side edges of an access door of a temperature-controlled cargo container. For example, the seal system may include mating seal members proximate to a top edge of a roll-up door of a refrigerated trailer, and may also include flexible side seal members proximate to the left and right side edges of the roll-up door.
