Independent packaging sourcing

custom folding carton

Start a procurement brief for a custom folding carton by naming paperboard grade, die line status, print process, quantity unit and destination. Custom Folding Carton Sourcing is an independent sourcing partner: we help US business buyers find candidate original plants, compare factory wholesale quotations on one specification basis and coordinate documents. We do not manufacture cartons, hold warehouse stock or act as an authorized factory channel.

What belongs on the first brief

  • Board and carton style

    Write SBS, CCNB or another named board together with paperboard caliper (18-24 pt is a common inquiry range, not stock) and the style: straight-tuck, reverse-tuck or crash-lock. A plant that quotes only a catalogue code still has to restate both the board and the style.

  • Die line and intended fill

    A die line that exists only as a retail photo cannot be nested. Name the intended fill so window film, grease barrier or food-contact files can be requested against that lot rather than as a site-wide badge.

  • Print, coating and sample path

    State whether the carton uses 4-color offset plus aqueous coating, flexographic printing, gravure printing or a short-run digital path. Sample cartons, plates and artwork revisions sit outside the piece price until the factory lists them.

  • Pack-out and freight

    Inner packs, carton count and pallet pattern change landed cost. Freight, cutting-die ownership and plate charges stay on separate quote lines so totals can be compared without mixing scopes.
