A proppant discharge system has a container with an outlet positioned in a bottom thereof and a gate affixed adjacent the outlet so as to be movable between a first position covering the outlet to a second position opening the outlet, and a support structure having an actuator thereon. The container is removably positioned on the top surface of the support structure. The actuator is engageable with gate so as to move the gate from the first position to the second position. A conveyor underlies the container so as to receive proppant as discharged from the container through the outlet. The container can be a ten foot ISO container.

A collapsible container, a method of manufacturing, and a method of using the same is provided herein. In some embodiments, the collapsible container is octagonal, generally square, or generally rectangular while comprising eight side panels have receiving pockets for receiving stiffening panels. The collapsible container may include a third layer sewn to the inside of the walls such that content loaded into the third layer is directed to a spout at the bottom of the third layer for convenient discharge of contents. The eight side panels are designed such that the container can be collapsed for easy transport but also stably supports and facilitates discharge of contents from the third layer when the container is set up.
