Buyer rows: fill, line and destination
Dry goods and confectionery cartons
A cereal or tea carton usually needs a named SBS or CCNB grade, paperboard caliper in the 16-24 pt range when that is the intended board, and a closed glue flap. Oxygen transmission rate and water vapor transmission rate matter only when a barrier coating or liner is specified; they are not implied by the word carton. If the fill is food-contact, request the migration testing file for that board and ink lot. Do not treat a site-wide badge as the file.
Personal-care and cosmetic sleeves
Secondary cartons around bottles or tubes often run on a different die line from the primary pack. Print registration, foil or spot UV, and whether the sleeve is a fifth-panel or a simple wrap should sit on the quote line. Flexographic printing or offset can both be quoted if plates are itemized. A lower piece price that drops a foil stamp is a different construction.
Window-patch retail packs
Window film, patch size and food-contact status of the film are separate from the paperboard. A tuck-end price cannot absorb an unnamed PET window. Ask each factory to quote the window as its own line, including waste allowance on the die. Sample path should be a struck carton, not only a digital mock.
Export and club-pack destinations
US destination state or postal code, carton count per pallet and any broker paperwork change freight even when paperboard caliper stays fixed. Edge crush test and flute profile belong to the outer corrugated shipper, not to the inner folding carton, unless the buyer has asked for a combined pack-out. Mixing those units hides the real order size.
Limitations: this desk does not promise US contract filling, does not publish a savings percentage, and does not treat a supplier preference as a verified factory grade. Continue to inquiry options or send the requirement.
