Illustrated comparison of two factory quote columns for double-wall boxes

double wall corrugated boxes

Prepare a comparable request so two plants quote double wall corrugated boxes on the same flute profile, strength method, inside size, print status and destination. This page is the matching method, not a factory appointment and not a claim that plants are already audited by this desk.

What every comparable factory quote should include

Same construction line

Flute profile, paperboard caliper if the packer already measured it, and whether strength is an edge crush test number or a burst number. If one plant quotes 32 ECT and another quotes 275 lb burst, convert the method before comparing. Inside length, width and depth must use one unit system on both replies.

Same commercial envelope

Quantity in pieces or cartons, incoterm, destination state, and requested delivery date. A piece price that hides partitions, pads or pallet pattern is not yet comparable to a packed-out price. Optional budget is a buying envelope, not a published market discount.

Costs that stay outside piece price

Ask each plant to list cutting dies, flexographic printing plates, sample lots, artwork revisions and freight. Those items stay outside the piece price so total procurement cost can be read. This desk does not invent a savings percentage from those lines.

Documents requested from the plant

Die line status, sample carton path, and any food-contact or ink migration testing file for that liner and ink lot. ISO ICS 55.020 is used here as unit vocabulary. A plant ISO 9001 file, when requested, comes from the named supplier, not from this website.

Questions that usually stall a comparable reply

Edge crush test and burst describe different lab methods. A buyer who asks one plant for 32 ECT and another for 275 lb burst is collecting two answers that cannot sit on one line until the method is named. We send the same method name to each plant rather than converting a number we did not measure.

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. Those two process paths need separate quote lines because plate amortization and color-match files are not the same object.

We do not promise US local converting, a published lead time, or a discount percentage. Food-contact and recyclable claims stay on the mill or ink file for that lot. A Packhelp quote brief observed on 2026-09-15 at quote.packhelp.com is a process reference for brief-first intake; it is not this site factory network.

Brief that cannot be compared versus brief that can

Before alignment

One email says heavy duty boxes, another says double wall, a third says 15 by 16. Quantity is a pallet. Print is mentioned without color count. Freight is inside one piece price and missing from the other. Those replies cannot be read as one procurement cost.

After one basis

Both plants receive RSC, BC flute, edge crush test named, inside 15 x 16 x 5 in, one-color flexo or plain kraft, 5,000 pieces, DDP to a named US state, requested date, and a list of die, plate, sample and freight exclusions. Only then do the two replies sit together.

Send the same brief to start matching

List tooling, plate, freight and document costs outside the piece price so two double wall corrugated boxes replies can be read together. No existing quotation is required.

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.
