Questions buyers ask before sourcing this category
Short answers for RFQ prep. Full buying guides are in Related Knowledge on this page.
What paperboard grades do rigid-box and carton plants buy from China?
Typical buys are grey board (chipboard) for rigid boxes, plus black card, white card, and kraft for cartons, bags, and inserts. Name the family and caliper—not only “cardboard” or GSM.
Why is caliper more useful than GSM alone?
Stiffness, wrap behavior, and lid warp track thickness and density more than a single GSM number. Ask how caliper is measured and the tolerance after conditioning.
What belongs on a grey-board RFQ?
Thickness + tolerance, density class, flatness, recycled-content documentation if claimed, odor limits for cosmetics/food-adjacent packs, packing/moisture protection, and substitution rules.
Can I switch board mills on a running gift-box SKU?
Not silently. Mill or grade swaps change wrap adhesion, warp, and magnet crush. Freeze an approved mill/grade pair and require a new wrapped sample before any substitution.
