Black Card and White Card Paper Buying Guide
Buyer guide to black card and white card paper from China for rigid boxes, folders, and print packs: GSM, stiffness, shade, coating, and RFQ fields for paperboard programs.
Quick answer
Buy black card and white card by locking GSM/caliper, shade, coating/finish, and end use (covers, cards, rigid wrap faces, folders). Do not RFQ “card paper” without color and stiffness targets—quotes will not be comparable.
Where these stocks are used
Rigid box wraps and lids, invitation/folder covers, high-contrast packaging panels, and some insert cards. They differ from grey board cores and from folding carton SBS—keep material families separate in sourcing.
Black card controls
Shade consistency, rub resistance, and whether the black is through-colored or surface-coated. Soft-touch or film lamination changes scuff and recyclability claims. Approve rub and fold cracking on real scores.
White card controls
Whiteness/brightness band, coating for print, and stiffness at target GSM. Food-contact or low-odor needs for cosmetics should be written. Recycled whites can vary lot-to-lot—set shade tolerances.
Converting notes
Die-cutting, foiling, and embossing behave differently on dense blacks vs coated whites. Ask for grain direction recommendations when warping matters on large lids.
RFQ fields
