Which mailer or box should you use?

Match the container to the product. Rigid and fragile goods want a corrugated box. Flat and non-fragile goods ship cheaper in a mailer. Here is how the common formats compare.

Format Best For Protection Notes
Corrugated box Heavy, fragile, or multi-item orders High, rigid walls Ships in the case, stacks on a pallet
Corrugated mailer Books, electronics, flat products Medium-high, folds around the item Ships flat, folds fast
Poly mailer Apparel, soft goods, non-fragile Low, tear and water resistant Lightest option, lowest postage
Bubble mailer Small fragile items, parts, jewelry Medium, padded lining Ships flat, cushions on contact
Mailing envelope Documents, catalogs, thin goods Low Cheapest way to mail flat items

Stretch wrap or strapping for a pallet?

Most operations use both. Wrap the load to hold it together, then strap it down so nothing shifts. Use stretch wrap to unitize a stacked pallet and keep dust and moisture off. Use strapping to lock heavy or rigid items in place for the ride.

Method Use it for Best with
Stretch wrap Holding and unitizing a stacked load, keeping out dust and moisture Boxed goods, mixed pallets
Strapping Locking heavy or rigid items down, stopping shift in transit Machinery, lumber, bundled goods

Frequently asked questions

Most shipping and mailing operations run on five things: an outer container, packing materials to protect what's inside, a way to seal it, a way to unitize a pallet, and the tools to do the work. Boxes and mailers hold the order. Void fill, bubble, and paper keep it from moving. Tape and sealers close it. Stretch wrap and strapping lock the pallet. Knives, labels, and markers keep the station moving.
