Self seal postal boxes use a built-in peel-and-seal strip so you can close a box securely without tape, speeding up packing for high-volume despatch. Parcelsend stocks these in the UK for same-day despatch, and they sit alongside our wider mailing boxes & cartons range.
How to choose the right self seal postal box
Pick a size that fits your product snugly, since the peel-and-seal strip works best when the box closes without excess gap.
How the peel and seal strip works
A protective liner covers an adhesive strip along the flap; simply peel it back and press the box shut for a strong, tape-free seal in seconds.
Where self seal boxes save time
They suit anyone packing multiple orders a day, since removing the need for a tape gun speeds up despatch without compromising on strength.

Frequently Asked Questions
How does the self seal strip work?
Each box has an adhesive strip under a protective liner; peel the liner away and fold the flap down to create a strong, tape-free seal.
Do I still need packing tape?
No, the peel-and-seal strip is designed to close the box securely on its own, though you can reinforce heavier or fragile items with our packaging tape if you prefer.
Are self seal boxes strong enough for postal despatch?
Yes, they're made from sturdy cardboard and many sizes fit within the Royal Mail Large Letter or Small Parcel bands, making them a reliable choice for everyday postal orders.
What sizes are available?
We stock a range of sizes suited to small and mid-sized items; compare your product against the Royal Mail Parcel Post System bands before ordering.
Can self seal boxes be reused if opened carefully?
The strip is designed for a single secure seal, so once opened it won't reseal to the same strength - for returns packaging, consider a fresh box or our mailing boxes & cartons range.
How fast will my order arrive?
These boxes are held in UK stock, so orders placed before our daily cut-off are despatched the same day.
