Kraft paper has been manufactured since 1906. Since then, pulp processing, paper making, and corrugating operations have been developed to a high state of efficiency and productivity. Today, in the corrugated cardboard industry, designers are creating innovative containers that require four-color printing and complex die-cutting. These innovative containers are designed with sophisticated software such as computer-aided design (CAD) programs, allowing a packaging designer to brainstorm different package designs before manufacturing begins. A designer using a CAD program can call up and modify different designs that have been stored in a computer design library. Thus, existing packages can generate new designs. Many retail stores use such light, strong, and colorful containers directly, as point-of-purchase displays.
