Structural board
Rigid boxes commonly use greyboard selected by thickness and density. Folding cartons use paperboard chosen by caliper, stiffness and print surface. Corrugated packaging adds flute selection, compression strength and edge-crush considerations.
Wrapping and face paper
Coated paper supports detailed offset printing and lamination. Uncoated and textured specialty papers create a more tactile, restrained appearance but may change color reproduction, foil performance and rub resistance.
Liners and exposed edges
Inside liners affect opening feel, cleanliness and brand color continuity. Wrapped edges, corner construction and paper grain direction influence the finished appearance of premium rigid boxes.
Responsible choices
FSC-certified papers, recycled content, molded pulp and paper-based inserts can reduce plastic use. Claims should match actual certificates and the complete material specification rather than relying on a generic eco label.
