Why Choose Plain Boxes?
Plenty of boxes never need print. Trade deliveries, warehouse moves, spare parts, internal transfers and storage all work perfectly well in plain brown board. Leaving print off saves the set-up cost and skips the proof stage, so plain boxes are both the cheapest and the quickest box we make.
Which Styles Can Be Plain?
All of them. Most plain boxes are regular slotted cartons, but plain lidded boxes are popular for storage and plain mailers for simple online orders where branding comes from a sticker or tape.
- Regular slotted carton: taped, economical, stackable
- Full overlap carton: double thickness top and bottom
- Box with lid: easy to open and reclose
- Plain mailer: tape-free opening for small parcels
Do Plain Boxes Look Unprofessional?
Not at all. Clean, well-fitting plain kraft boxes look tidy and purposeful, and many shops prefer the understated look. If you want a little branding without printed boxes, a printed tape or a label on one panel does the job for very little cost. When you are ready for print, the same size can move to printed cardboard boxes with your logo without changing anything else.
How Do You Order Plain Boxes?
Because there is no artwork, a plain order needs only a handful of details.
- Pass on the internal length, width and height in millimetres.
- Tell us the quantity, or two quantities to compare.
- Say what goes in the box, so we can confirm the board.
- Approve the quote by email.
- Boxes are made and delivered flat.
Which Board Should Plain Boxes Use?
Pick the board for the load, not for looks. Light, soft goods are fine in B flute; bulkier goods benefit from C flute; heavy or stacked goods belong in double wall.
| Load | Board | Note |
|---|---|---|
| Light and small | Single wall E flute | Thin, neat, saves space |
| Everyday parcels | Single wall B flute | The usual choice |
| Bulky but not heavy | Single wall C flute | More cushion |
| Heavy or stacked | Double wall BC flute | Holds its shape |
What Do Plain Boxes Cost?
Plain boxes start from £0.20 a box. With no print set-up, the price is driven almost entirely by the size, the board and the quantity, which also makes it easy to compare two sizes or two grades on the same quote.
Can You Add Print Later?
Yes. Many businesses start plain and add a logo once sales settle. We keep your sizes on file, so moving to a printed version means sending artwork and approving a proof, nothing more. You can also mix the two: printed boxes for customer orders and plain ones for trade.
Storing Plain Boxes
Boxes arrive flat and banded. Keep them off the floor and away from damp, and they stay square and ready to use. Store each size in its own labelled stack near the packing bench so the right box is always to hand.
Sizing Your Plain Cardboard Boxes
Plain boxes are quoted on the inside size in millimetres. Since there is no artwork to adjust, changing a size is easy, so it is worth getting the fit right rather than settling for a near miss.
If you need several sizes, list them together. Mixed plain orders are common and are priced on one quote.
Board for Plain Cardboard Boxes
Plain boxes come in every corrugated grade. Single wall B flute suits most loads; move to double wall when weight or stacking demands it.
| Board | Thickness (mm) | Strength | Best for | Print finish |
|---|---|---|---|---|
| Single wall E flute | about 1.5 | Light | Small mailers, postal boxes, retail packs | Very good, sharp print |
| Single wall B flute | about 3 | Medium | Shipping boxes, mailers for everyday parcels | Good |
| Single wall C flute | about 4 | Medium, more cushion | Larger parcels that need some give | Good |
| Double wall BC flute | about 7 | Strong | Heavy, fragile, stacked or palletised goods | Fair, best for 1 or 2 colour |
