wholesale heavy duty corrugated boxes

How a wholesale request is made comparable

Packhelp quote and wholesale pages, observed 2026-09-15, show a brief-first path: the buyer writes format, quantity and artwork before a coordinator returns options. That is a process reference, not this site factory network, die shop or lead-time clock. ISO ICS 55.020 supplies unit vocabulary only.

1. Lock the carton object

   Confirm style, flute profile and whether strength is quoted as edge crush test or burst. A wholesale heavy duty corrugated boxes line that only says strong box cannot be sent to more than one factory without silent substitutions. A 44 ECT single-wall RSC is not a drop-in for a 275 lb burst double-wall carton.

2. Split print and tooling from converting

   Ask each factory to quote converting, then list cutting dies, flexographic printing plates, extra colors and varnish as exclusions. Digital print may drop plate cost on short SKUs; it is not automatically cheaper once color registration and run length are named. Stable long marks often keep spot color on flexo.

3. Align quantity and destination

   Write pieces or cartons per size, pallet pack-out and the US ship-to state. Freight, duties and document sets stay outside the piece price so two replies can be subtracted on the same basis. Humidity and container dwell belong on the brief when they change stack life.

4. Hold sample and file gates

   An unprinted structure sample on the named board comes before a production release. Food-contact or migration testing claims need the liner, adhesive and ink files for that lot, not a homepage badge. Sample freight stays outside the unit unless a named reply says otherwise.

Costs that stay outside the piece price

Buyers often ask for one all-in number. That hides the items that actually move between factories. Keep these on their own rows so a later artwork change does not look like a carton-price increase:

• New or revised cutting dies and any flexographic printing plates
• Die-line redraws when the blank, flap or partition changes
• Freight to the named destination and any pallet or carton upgrade
• Product documents such as an ECT or burst sheet, or a liner food-contact file, if required for that fill

Limits we will not paper over

• Edge crush test and burst are not interchangeable methods; pick one and keep it on every reply.
• We do not publish a savings percentage without a same-spec, same-quantity, same-delivery comparison owned by this site. brand_config lists no price_comparisons.
• Post-consumer recycled content must name the ply and the claimed percentage on the mill sheet, not on our homepage.
• Paperboard caliper belongs to folding cartons. It does not replace flute profile or ECT on a corrugated line.

We then collect factory replies against that same list. Preference for high-end, mid-range or budget converting is a buyer choice about board grade, print coverage and document depth. It is not a rating we have verified. Review inquiry options before you send the brief.
