Overview
Cardboard boxes here means kraft corrugated cartons for shipping and storage in single, double, and triple wall grades, sold in bundles and bulk cases. The collection also carries the paperboard formats that get grouped under "cardboard" in real warehouses: 24pt fibreboard folding cartons, rigid chipboard stayflats mailers, and spiral-wound fibreboard mailing tubes. If you are sizing cartons for a specific load, what size box for dishes walks through the working method: measure the packed contents, add cushioning room, and match a stock size.
What this collection covers
- Corrugated boxes in ECT-32 kraft, including multi-depth cartons like the 12.5x12.5x12 multi-depth box and the 17.25x11.5x11, which score down to shorter heights so one carton covers several product sizes.
- Folding cartons such as the 3x3x3 white reverse tuck carton in 24pt fibreboard, used as retail-style inner packaging rather than as the outer parcel.
- Chipboard stayflats mailers with tab-lock closure, from 7x9 up to 27x20, for documents, prints, and flat goods that must not bend.
- Mailing tubes in spiral-wound fibreboard with caps, from 3x24 to 4x42, for posters and long parts. The mailing tube size chart maps contents to tube sizes.
How to choose
| Decision | How to make it |
|---|---|
| Wall grade | Single wall handles routine parcels. Step up to double or triple wall for heavy, dense, or palletized loads, not because a product feels valuable. |
| Corrugated vs. paperboard | Corrugated takes stacking and carrier handling. Fibreboard cartons and chipboard mailers protect shape and surface but are not outer shipping boxes for heavy items. |
| Fixed vs. multi-depth | If your products vary in height, multi-depth cartons cut the number of box SKUs you keep on the shelf and reduce the void fill each order needs. |
| Size | Measure the packed product, add room for cushioning, and stop. Oversized boxes cost you twice: more void fill and more billable cube. The box size finder and box quantity guide do the arithmetic. |
Freight is part of the price
Boxes are light but bulky, so freight is priced on the space they take, and on a small order it can rival what the boxes themselves cost. Most suppliers let you discover that at checkout; we would rather you plan for it. Order in bundle and case quantities so freight spreads across more units, and combine boxes with tape and void fill in one shipment. The underlying numbers are in the packaging cost and cube index.
