book wraps

book wraps are flat corrugated cardboard mailers that fold closely around a book and hold it firm while it travels through the post. A good wrap grips the covers, guards the corners and spine, and adjusts to the thickness of the title inside, so a slim paperback and a chunky hardback can both travel safely without loose space around them.

How book wraps work around your titles

A wrap starts as a flat sheet of corrugated board with scored fold lines. You place the book in the centre, fold the sides over in sequence, and the scores let the board settle at the depth your book needs rather than at one fixed depth. That close fit matters because movement inside packaging is what bends corners, scuffs dust jackets and splits spines. A wrap that hugs the book removes that movement while adding very little weight, which helps keep your parcel inside the postage band you planned for.

The parts that do the protecting

The fluting inside corrugated board acts as a cushion of trapped air, absorbing knocks from sorting machinery and from other parcels. The outer liner gives a smooth surface for a postage label and for print, while the folded edges create double thickness exactly where books suffer most, along the corners and the fore edge.

Why the edges matter most

Most book damage in transit is corner damage. A dropped parcel lands on a corner, so folded board that wraps around each corner spreads the force instead of letting it crush one point of the cover. Choosing a wrap with generous fold over flaps is the simplest way to protect collectable and signed editions.

Sizes, formats and Royal Mail bands

Measure your book at its widest points, including any slipcase, then allow a small margin for the board to fold. Slim titles packed tightly in a wrap can sit inside Royal Mail large letter limits of 353mm by 250mm by 25mm and 750g, while thicker books usually move into the small parcel band of 45cm by 35cm by 16cm and 2kg. The Royal Mail guide to sending small parcels sets out those limits in full, and checking your packed parcel against them before you buy postage avoids surprises at the counter.

Publishers, booksellers and marketplace sellers often keep two or three wrap sizes that cover most of their catalogue, because the adjustable depth means one size handles a range of thicknesses. Our book wrap mailers and book mailer boxes show the formats UK sellers use most, and slimmer orders can also suit large letter postal boxes when the book is thin enough.

Print, presentation and packing well

A printed wrap turns a plain delivery into a recognisable parcel from your shop, with your name, logo and care message on the outside and, if you wish, a thank you note printed inside. Print also helps returns, because customers can identify the sender at a glance. For packing, place the book with its spine against one fold, close the wrap firmly without forcing it, seal the flap fully, and add a stiffener only for very flexible paperbacks or thin magazines.

Who buys wraps most often

Independent bookshops, second hand sellers, comic shops, calendar publishers and print sellers all rely on wraps because they store flat, pack quickly and keep postage predictable. If you post mixed flat goods such as prints, comics and catalogues alongside books, tell us your full range when you request a quote and we will size the wraps around your largest regular item. Custom Postal Boxes manufactures in Wolverhampton, offers low minimum order quantities, free design support and free UK delivery, and pricing depends on size, material and quantity.

FAQs about book wraps

What can I send in book wraps?

You can send paperbacks, hardbacks, comics, magazines, calendars, catalogues and other flat printed goods. The wrap folds to the thickness of the item, so anything flat and fairly rigid that needs corner and cover protection is a good match.

Are book wraps stronger than padded envelopes?

Yes, for books they usually protect better. Corrugated board holds its shape and guards corners and spines, while a padded envelope is soft and lets corners bend. A wrap also keeps the book still, which stops covers rubbing during the journey.

Can book wraps be printed with my shop name?

Yes. Wraps can carry your logo, shop name, web address and handling messages, printed outside or inside. Free design support is included, so artwork is checked for position and legibility before production begins.

How do I choose the right wrap size?

Measure the largest book you post regularly, length, width and thickness, and choose a wrap that folds comfortably around it without forcing the flaps. If you post several sizes, two wrap sizes usually cover a whole catalogue well.
