Abstract: Various examples are provided for collapsible storage containers. In one example, among others, a storage container includes a rectangular bin, a reinforcing liner sheet, and clamping handles. The rectangular bin can include a cavity defined by a bottom and a plurality of sides including opposite sides having handle openings. The reinforcing liner sheet can include side sections separated by a bottom section, where the side sections include handle openings. The bottom section can be configured to align with the bottom of the rectangular bin and the side sections can be configured to align with the opposite sides of the rectangular bin when the reinforcing liner sheet is inserted into the cavity. The clamping handles can be configured to pass through aligned handle openings in one of the opposite sides and one of the side sections, thereby securing the reinforcing liner sheet in the rectangular bin.
