Abstract: A reusable dense packaging system used to transport large size display substrates, is provided made up of three main components; a pallet frame, a cover, and restraining means. The restraining means securely hold the glass sheets within the cover and on the pallet frame. Restraining means includes one or more retaining bars moving towards and away from the front of the glass sheets and a mechanical system. The mechanical system may include the use of a pressing panel, a belt apparatus, a scissor-like mechanism, positioning devices, or a retaining bar pulling system, each capable of moving towards and away from the front of the glass sheets. Each embodiment allows for packaging from 1 to N glass sheets with flexibility and stability and with manual or automatic operation.
