A foldable tote box is made of one-piece board of corrugated plastic. It comprises a rectangular bottom panel of two side edges and two end edges, a pair of side-wall panels, a pair of end wall panels, and two pairs of corner filler beam panels. Each side-wall panel has a folding edge integrally connected to the side edge of the bottom panel, and is folded along a first scored folding line at the folding edge, and has a cover panel connected to its top edge and two end edges defining a width of the side-wall panel and the height of the box. The end-wall panels are respectively integrally connected to and extended from the end edges of the bottom panel and folded along second scored folding lines. Each pair of corner filler beam panels is connected to the end edges of each end-wall panel. Each filler beam panels extends from the end edge of the end-wall panel and is folded along a third scored folding line to form a hollow support beam. A first pair of locking insert tabs is formed in cutting lines on the side-wall panel and engaged with a first pair of holding tabs, each of which is formed on the corresponding filler beam panel so as to secure the support beams formed of the filler beam panels against the wall of the box. Each locking insert tab and its corresponding holding tab are oriented in the same direction.
