A packing insert is shown, which includes a first face, a second face, opposite the first face, a first side support and a second side support. The first side support is flexibly connected to the first face and the second face, preferably to one edge of each face. When not fully extended, the side supports bend inwards between the first face and the second face, and they are in positions with respect to the first face and the second face and each other such that when they are bent inwards between the first face and the second face, the first support member does not interfere with the second support member. In different arrangement, each side support includes a forward support member flexibly connected at one end to one edge of the first face and a rear support member flexibly connected at one end to one edge of the second face. The forward support member and the rear support member are rotatably connected to each other at their ends which are opposite the first face and the second face. In various forms, each side support includes a multi-position locking hinge or a cam-locking hinge or a tension spring hinge rotatably connecting the forward support member to the rear support member. The distance between the first face and the second face is adjusted by changing the angles formed by the first side support and the second side support. In one form, the first face and the second face are both substantially planar.
