Restate the mailer
We write style, L x W x D, flute, print colors, finish and pieces per artwork. You confirm the restatement before anyone is asked to quote.
custom corrugated mailer boxes
Custom corrugated mailer boxes need a die line, board, print count and quantity unit before several plants can answer the same request. Corrugated Shipping Boxes Sourcing restates those fields; you approve the written brief. We coordinate factory replies. We do not cut dies, print plates, or ship from our own dock.

Coordination steps that stay on one mailer brief
A mailer is not an RSC with the flaps redrawn. Inside dimensions, hinge style, and whether the print wraps a crash-lock base change plate and die cost. Flexographic printing on a long, stable artwork often keeps unit cost and spot-color control; digital print can reduce plate cost when SKU count is high and art changes often. Those are trade-offs to write down, not a ranking of plants.
Find plants that publish this style
A plant that only lists bulk RSC shippers is a different conversation, even if board grade looks similar. Mailer lock style and print path have to appear in their public range or in a written reply.
Line up the same extras
Die, plate, sample, cartonization and freight stay outside the piece price. An offer that hides the die is not compared with an offer that lists it.
Hold the sample path
Ask for a structural sample or printed proof against the frozen die line. A photograph of another brand's mailer is not a sample of the quoted construction.
Track the written checks
We follow the document list you approved. We do not approve artwork legally, file trademarks, or sign a packing specification as if we were the mill.
Counts that belong on the comparison sheet
The figures below are checklist sizes, not factory capacity, customer counts, or a service score. They exist so several replies can be read side by side.
4
Quote lines to keep separate: piece price, die or plate, sample, freight to the named ZIP.
3
Files to request for the named construction: board or ECT/burst record, print proof method, packing list basis.
2
Print paths to declare: flexographic printing for a stable long run, or digital print for short, changing art.
1
Die line revision that all plants must quote. A second lock style is a second brief.
Limitations stay visible: we do not hold mailer inventory; we do not convert a 32 ECT claim into a drop-test result; we do not treat a mill ISO 9001 certificate as proof of the flute on your pallet. Continue to inquiry options or the RFQ note.

Name destination and requested timing. Optional budget and supplier preference help narrow the search; they are not verified factory grades.
