custom heavy duty folding cartons

Use this shortest custom heavy duty folding cartons checklist before you accept an alternative construction. Open specification choices block a comparable quote. Paperboard Folding Cartons Sourcing is an independent sourcing partner: we help you write the missing fields, then request factory wholesale replies on one basis. We do not rate suppliers or publish a savings percentage.

Why a short list still has to be complete

A custom heavy duty folding cartons reply that names only a piece price leaves the buyer comparing different objects. One plant may include the cutting die, another may omit aqueous coating, and a third may quote freight to a warehouse that is not your destination. The story of a usable brief is the story of the same line items written once.

Keep board, style, glue chemistry, print process, quantity unit and destination on one RFQ line. Alternatives need a second line, not a silent substitution.

Packhelp quote and wholesale pages (observed 2026-09-15) show a brief-first coordinator path. That is a process reference. It is not this desk's factory list, sample calendar or discount table. ISO ICS 55.020, recorded 2026-09-20, supplies unit vocabulary only.

If a factory offers a thinner board or a window-film patch, write the change as an alternative construction. Accepting a substitution without restating paperboard caliper, coating, adhesive and food-contact files is how two quotes look cheaper while describing different packs. Heavy-duty language here means a named higher-caliper or laminated paperboard carton, not a corrugated flute profile and not an edge crush test value copied from a shipper RFQ.

Open choices that still block a comparable quote

Name SBS, CCNB, CRB or a laminated grade, paperboard caliper, and straight-tuck, reverse-tuck, crash-lock or auto-bottom. State whether a die line exists as a production file or only as a photo. A missing die line is a tooling line, not a rounding error. Do not accept a flute-profile substitution; that language belongs to corrugated boxes.

Write color count and whether the run is digital, offset or flexographic printing. Name PVA or hot-melt for the side-seam and, if a window is specified, the window-patch adhesive. Sample cartons and plate charges stay outside the piece price until listed. Gravure printing belongs on the brief only when that process is actually wanted.

Ask for migration testing or a food-contact file only when the fill needs it. Post-consumer recycled content needs a mill sheet. Before accepting an alternative construction, verify board, coating, window film, adhesive and destination packing still match the original use. Mono-material recyclability claims do not replace a named board lot.

Limitations we keep explicit: this desk does not own plants, does not hold carton inventory, does not file FDA or recycling-claim approvals, and does not publish a reply clock. Digital print versus conventional offset remains the buyer's run-length choice. A heavier fill may still need a corrugated master; burst strength on that master is a separate check.

Send the locked list

Include optional budget currency and whether the figure is per piece or for the whole order. High-end, mid-range, budget or undecided is a finish and documentation preference, not a verified factory grade. Review inquiry options if the construction is still open.

Write format and intended contents; quantity by specification or artwork; material, size, barrier or 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 and die line files can be described after we reply; this form has no upload field.
