corrugated box

Resolve open specification choices on a corrugated box 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. The other priced flexographic printing with plate amortization. Those replies look like the same corrugated box 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. Neither claim becomes a badge on this website. 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 the 15 x 16 x 5 inch shape when that is the measured SKU. A plant that offers a nearby size is offering a different object. Write whether the print sits on the outer liner only.

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 or a different ECT number, 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.

Send the open specification questions

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.

Write product format and intended contents; quantity by specification or artwork; material, size, flute profile and board grade; print colors, finish and sample needs; destination state or postal code and requested delivery date; required product documents. Optional target budget with currency and unit or whole-order basis; optional supplier preference (high-end, mid-range, budget or undecided). Drawings or die-line files can be sent after we reply; this form has no upload field.
