Corrugated RSC blanks on a packing table with a flute caliper and die-line sheet

Independent sourcing partner

custom corrugated boxes

Start the procurement brief with the measured product form: custom corrugated boxes for US business packing, not retail moving kits. Share flute profile, ECT or burst, inside dimensions, print status, quantity unit and destination so factory replies can sit on one line.

Material

Kraft liner, test liner, or a named PCR kraft lot with the mill sheet attached.

Size

Inside length, width and depth in mm, plus board caliper if the packer already measured it.

Print

Flexographic printing colors, die line status, and whether a sample carton is required.

Quantity

Pieces or cartons by size, plus the ship-to state or postal code.

What belongs on the first brief

  • Same construction on every quote line

    Name the box style (RSC, HSC, or die-cut tray), flute profile (E, B, C or BC), and whether strength is quoted as edge crush test or burst. A 32 ECT single-wall RSC and a 275 lb burst double-wall carton are different objects.

  • Quantity unit that factories can price

    Write pieces or cartons by size. Mixing a pallet count with a piece count on the same line is how two factories look cheaper for different reasons.

  • Destination and document list

    State or postal code changes freight and sometimes board availability. Food-contact or ink migration files bind to liner, adhesive and ink lots, not to this website.

  • Costs that sit outside piece price

    Cutting dies, printing plates, artwork revisions and inbound freight stay as separate lines. This site does not publish a discount percentage.

Where the brief usually starts

Ecommerce fulfillment

RSC sizes that must nest on a named pack-out table, often with a one-color flexo mark.

Food distribution

Board and adhesive files for the fill, plus humidity notes if the carton sits in cold rooms.

Industrial shipping

Stack-path questions that need ECT or burst named, not a generic heavy-duty label.

Die-cut retail trays

Die line, flute, and print process before treating a die-cut as an RSC substitute.
