An environmentally-controlled food container, such as a refrigerator, freezer or oven, includes a plurality of walls joined at their edges and joints between adjacent walls. The joints are covered by a seaming tape which includes a plastic film layer and a mesh layer. The mesh layer is formed from a material having a coefficient of thermal expansion within 짹10% of a coefficient of thermal expansion of adjacent wall material. The seaming prevents moisture and bacteria from entering the joints, and does not fracture due to thermal expansion and contraction of the walls.
