custom made corrugated boxes
Resolve open specification choices on custom made corrugated boxes before two factory quotes are treated as comparable. Artwork, die line, sample carton and revision path decide whether a later piece price still belongs to the same object.
What still blocks a comparable quote
A sample carton that passed last month does not cover a new die line, a new flute, or a new ink set.
Buyers often arrive with a drawing and two plant emails. One plant priced a digital print short run on clay-coated white. The other priced flexographic printing with plate amortization on mottled white. Those replies look like the same custom made corrugated boxes until color count, plate fees and sample rules are written on their own lines.
High SKU counts and frequent artwork changes can reduce plate cost with digital print. Stable long runs often keep unit cost and spot color control better in flexographic printing or offset. That trade-off is a buyer choice. It is not a claim that one process always costs less, and it is not a discount percentage published by this desk.
Food-contact or recyclable language, when needed, travels with the liner and ink lot. Post-consumer recycled content is a mill-sheet statement. A clay-coated white face can improve print holdout while complicating some mill recycle claims; that tension belongs on the RFQ, not on a website badge. ISO ICS 55.020 remains unit vocabulary for packaging, not a certificate we hold.
Prepress and sample checks before you accept an alternative construction
Confirm inside length, width and depth on the die line, including any measured SKU size you already use. A plant that offers a nearby size is offering a different object. Write whether the print sits on the outer white liner only and whether the inner face stays kraft.
State whether you need a plain construction sample, a printed sample, or both. A later printed sample can reopen plate or digital setup fees. This form has no upload field; die-line files can be sent after we reply.
If a plant offers a different flute, a different ECT number, or a kraft face instead of white, treat that as a new RFQ line. Accepting an alternative construction without restating strength method, paperboard caliper and destination is how two replies stop being comparable.

List die line status, sample type, print process and any alternative construction you still need to verify. Review inquiry options if the size is already chosen.
