Cardboard sheets are flat, cut-to-size pieces of corrugated or solid paperboard used as dividers, pads, layer separators and protective backing. TBPB makes them custom with no minimum order, and if you hold a written quote for the same specs we will beat it.
What the sheet is for decides the board
People ask for cardboard sheets to do very different things. A sheet that sits under a product in a box needs stiffness. A divider between glass jars needs to stay upright. A layer pad between stacked cartons on a pallet has to carry weight and keep its shape. A backing board behind a print or a hanging card mostly needs to stay flat. Say which one you need, because a thin solid board that works as a backing will buckle as a divider.
Corrugated or solid board
Corrugated board has a fluted layer between two liners, which gives it cushion and stiffness for its weight. Fine flutes such as E-flute are thin and print well, while B-flute and thicker walls carry more load. Solid paperboard, such as chipboard or a folding carton stock, is thinner and denser, and it suits flat inserts, cards and backing where you need a smooth, printable surface. For the heaviest protection, corrugated beats solid board on a weight-for-weight basis, though neither matches foam for shock absorption.
Grain direction matters. Board bends more easily one way than the other, so tell us if the sheet will be flexed or must stay rigid in a specific direction.
Size, cut and print
Give us the finished length and width and the thickness you want. If the sheet must slide into a carton, measure the inside of the carton and take a small clearance off each dimension so it drops in without snagging. Sheets can be cut square, or die-cut with notches, slots, hand holes or rounded corners. Printing is available on one or both sides in CMYK or Pantone colors, or you can keep a plain kraft face. Printed sheets double as branded layers in a gift box or a shipping parcel.
- Board: corrugated (fine to thick flute), solid paperboard, kraft
- Cuts: square, die-cut, notched, slotted, rounded corners
- Print: plain kraft, one-color, full color on one or both sides
- Uses: dividers, pads, layer sheets, backing boards, packing layers
- Sizes: made to your length, width and thickness
When a box or insert is the better answer
If the sheet exists to stop a product moving, a shaped paper insert usually holds better than a flat piece. For shock protection, look at custom foam inserts. If you also need the carton, our cardboard boxes are made to match, and the whole cardboard box range is easy to browse.
A good check: stack your real product on a sample sheet, lift the sheet by one edge and see how much it sags. If it bends noticeably, move up a thickness.
It also helps to say how the sheets will be stored. Flat bundles on a pallet are fine, but long sheets leaning against a wall can bow over time. If you have limited space, ask us about nested or smaller stacks so the board reaches you in good condition.
Next step: send the size, the job and the quantity, even one sheet, and TBPB suggests a board and quotes it.
Frequently asked questions
What are cardboard sheets used for?
They work as dividers, pads, layer separators, backing boards and protective layers inside boxes and on pallets. The job decides the board: dividers need stiffness, pads need compression strength, and backing boards mostly need to stay flat. Tell us the use and we recommend the board.
Should I choose corrugated or solid cardboard sheets?
Corrugated gives more cushion and stiffness for its weight and suits heavier loads. Solid paperboard is thinner, denser and prints more smoothly, which suits flat inserts and backing. For serious shock protection, foam is better than either, so consider it for fragile goods.
How do I specify the size of a cardboard sheet?
Give the finished length and width and the thickness you want. If it slides into a carton, measure the inside and take a small clearance off each side. Send those numbers, and tell us any notches or slots, and we draw the cut for approval.
Can cardboard sheets be printed?
Yes. We print one or both sides in CMYK or Pantone colors, or leave a plain kraft face. Printed sheets can double as branded layers inside gift boxes or parcels. Heavy corrugated takes a rougher print than smooth solid board, so choose by the look you need.
Is there a minimum order for custom cardboard sheets?
No. TBPB has no minimum order, so you can order a single sheet to test the board or thousands for production. Send the size and use for a quote, and if you hold a lower written quote for the same specs, we will beat it.
Can you die-cut cardboard sheets?
Yes. Besides square cuts we can add notches, slots, hand holes and rounded corners, which turns a flat sheet into a divider or a layer pad that locks in place. Send a sketch or the sample you want to match and we return a drawing to approve.
