Epp box

Abstract

The invention discloses an EPP box, comprising a box bottom and a plurality of side walls removably arranged on the box bottom; the plurality of side walls are connected pairwise to form a removable frame. In the EPP box, because the plurality of side walls are removably connected to form the frame for arranging components, the side walls are individually made, the dimension of each side wall is accurately controlled, and then the inside dimension of the frame is conveniently controlled; only the damaged side wall(s) is replaced when part of the EPP box is damaged while in use without discarding the whole box body, and the production cost is greatly reduced.
