Boxes and mailers are bought for protection, shipping cost and brand presentation, and the specification matters as much as the price. Get exact internal dimensions, board grade and print method in writing, and order a sample before a bulk run.

The main formats are corrugated shipping cartons, mailer boxes that fold into a tuck-top or lid style, rigid gift boxes, folding cartons, padded envelopes, poly mailers and bubble mailers. Corrugated board is made in single-wall and double-wall construction, with flute profiles that differ in crush resistance and print quality. Folding cartons use paperboard, which is thinner and suited to lighter retail items. Poly mailers are lightweight and low cost but give no crush protection. Choose by what the product needs: fragile goods need rigid corrugated with inserts, while soft goods can go in poly or paper mailers.
Always request internal dimensions, given as length, width and height in that order, and measure your product with allowance for padding. Boxes that are too large raise shipping costs through dimensional weight pricing, and boxes that are too small cause damage. Ask what tolerance the supplier works to, since board thickness reduces internal size. Order samples in the exact size and test with a real shipment.
Custom boxes can be printed on the outside, inside or both, using flexographic, digital or offset printing. Flexographic printing suits large runs of simple designs, digital suits short runs, and offset gives the best colour for retail boxes. Ask about plate or setup charges, proofs, colour matching and the lead time for custom work. Finishes such as lamination, foil and embossing add cost and time. Stock sizes with a plain or one-colour print are cheaper and arrive faster.
Stock boxes are sold in bundles or pallets, while custom runs have minimums that reflect the setup cost of tooling and printing. Ask about quantities per bundle, pallet dimensions and whether the supplier ships flat. Boxes are bulky, so freight is a big part of landed cost. Peak seasons, especially before the holidays, stretch lead times, so order early.
Packaging for food or cosmetics may need to meet specific rules, so check the requirements for your market. Recycled content or certified paper claims should be backed by certificates. Quality risks include weak board that crushes in transit, poor glue joints and colour variation between runs.
Questions to ask
Measure your product, add space for padding and order a sample to test. Oversized boxes increase carrier charges, and undersized ones lead to damage.
A mailer box is a one-piece folding box suited to e-commerce and presentation, while a shipping carton is a heavier corrugated box that protects goods in transit. Fragile items usually need the latter or an inner insert.
Custom boxes need tooling, print plates or digital setup, and machine time. Minimums spread this cost across the run, though digital printing allows smaller quantities.
Most suppliers provide stock samples and often charge for custom ones. Test the sample with your product and a real shipment before committing.
