Rigid boxes can be constructed in various styles. Some of our standard styles include the 2-piece telescoping box, cigar style box, book box, slipcase, literature box, and drawer box. Manufactured with chip board or graphics board. Our graphics board is the smoothest, rigid, heavy gauge chip board available. Made of 100% recycled content, graphics board is available for 50 point up to 145-point thickness, over 1/8” thick. When you need heavy duty, Petra and Holum can deliver.
