- Construction
- A separate base tray and a corrugated sleeve for the side walls
- Return
- Knocks down flat or comes apart for return shipping
- Footprints
- Same pallet footprints as a one-piece box
How it is built
The tray bottom is a shallow corrugated base. The sleeve is the four side walls of a gaylord made as one tube. Set the sleeve into the tray and you have a box. Pull it apart and each piece stores flat. Most gaylords are die-cut and assembled from a tray plus a sleeve in this way, and a sleeve and tray is the version built to come apart again and be reused.
That makes it useful where boxes cycle: a supplier that ships to a plant that sends the sleeves back, or a warehouse that stores empties knocked down (KD) and needs space. Folded flat, a stack of sleeves and trays takes a small share of the floor that built boxes take.
What to check on a used one
- Does the sleeve sit square in the tray, with no gap at the corners?
- Is the tray bottom flat and dry, with no crushed edges where the pallet nails were?
- Are there staples, tape or strapping holding the pair together, and are they sound?
- Is the maker's stamp still readable on the sleeve? The stamp rates the walls.
A sleeve and tray carries dense parts only as well as its tray and joints allow. For castings or small dense parts, ask for a one-piece full flap bottom instead, or ask us what the tray was rated for. See bottom styles.
Who asks for it
Suppliers that return packaging to a plant, warehouses that want to store empties flat, and sellers with a lot of single-trip sleeves left from inbound freight. If you have trays and sleeves to sell, describe how many sets and whether they are matched. See selling empties after a launch and the grade sheet.
Facts and figures
- Gaylord boxes range from 2 to 5 layers of cardboard, and many are sized for 40 x 48 or 45 x 45 inch pallets. (blog.containerexchanger.com, retrieved 2026-11-10.)
- The Cary Company lists gaylords in single wall 200#/ECT-32, double wall 275#/ECT-48 and triple wall 1100#/ECT-90 across sizes from 36 x 36 x 36 to 48 x 40 x 36. (thecarycompany.com, retrieved 2026-11-10.)
Terms
- sleeve: The four side walls of a gaylord made as one tube, set into a tray bottom.
- tray bottom: A shallow corrugated base that a sleeve sits in.
- knocked down (KD): Folded flat for shipping or return.
- die-cut: Cut and scored in one press pass; most gaylords are die-cut and assembled from a tray plus a sleeve.
- lid (cap): A corrugated top cut to the box's footprint; often sold separately.
Storing sleeves and trays
Knocked-down sleeves and trays store flat, but they need a dry corner and a pallet under them. Keep the fold lines clean, since a crease that has been bent twice loses stiffness.
