An improved binder formed of two cover portions made of rigid material joined together with a living hinge. A closure flap with a second living hinge joins the free ends of the cover opposite the binder spine. An improved method of attaching a pocket to the binder is also disclosed. The use of such a technique on rigid polypropylene material allows roll feeding of materials, eliminates the need for a chipboard, allows existing printing and sealing machinery to be employed in the manufacture of the binder, and provides improved durability and aesthetics at a low cost.
