Independent packaging sourcing

printed corrugated boxes

Start a procurement brief for the measured printed corrugated boxes family: a named flute profile, a print process, and a quantity unit in pieces, cartons or pallets. Printed Corrugated Boxes Sourcing is an independent sourcing partner. We help US packaging buyers locate candidate original factories and compare wholesale quotations on one construction, quantity unit and destination. We do not corrugate board, keep warehouse pallets, or sell under a brand appointment.

Before factory matching, write inside length x width x depth in mm, flute (E, B, C or BC), edge crush test or burst method, color count, piece or carton quantity, and the receiving state or ZIP. Cutting dies, flexographic printing plates, sample freight and pallet pack-out sit outside the piece price. No discount percentage is published because this site has no same-spec quote pair on file.

What this desk checks before a factory is asked to quote

One construction per RFQ line

Inside size, flute profile, board grade and print family stay together. A C-flute 32 ECT regular slotted carton with two-color flexographic printing is not interchangeable with a BC-flute mailer that needs a locked die line, even when both are corrugated.
Factory matching on written facts

Candidate plants are approached with the same brief. Edge crush test sheets, food-contact or migration testing files, and print drawdowns belong to the named factory and named lot—not to this service as a site-wide badge.
Quote comparison on total cost

Piece price, die or plate charges, sample freight, and destination packing are lined up as separate cells. ISO ICS 55.020 unit language (pieces, cartons, pallets) is used for vocabulary, not as a certification claim.
Sample and document path

Ask whether a first-article carton, a pallet pack-out drawing, and a lot file for the intended fill are included or extra. Those files travel with the lot. They are not implied by a directory name.

Where buyers usually place this box family

These tiles describe fill uses that change the RFQ. They are not stocked SKUs and they are not a claim that any factory is pre-approved.

Retail shipper print

Outer brand panels, barcode panels and a named color count belong on the first line, not after the board is already priced.

Food pack-out

Write the fill and whether a food-contact or migration testing file is required for the liner that will sit against the product.

Industrial parts

Heavier flute or double-wall and a named edge crush test method change both the piece price and the pallet stack note.

Parcel and mailer

Die-cut mailers and regular slotted cartons do not share one die or one ECT cell, even when the outside print looks similar.

Compare factory quotes

Include artwork or die-line status, quantity unit and destination. High-end, mid-range, budget or undecided is a buying preference, not a verified factory rating. No existing quotation is required.
