Collection: Book Wrap Mailers

Book wrap mailers are flat-pack board mailers that wrap and self-lock around the item — automatically sizing to the depth of the contents. Constructed from 500–550gsm solid board, they give rigid protection against bending, crushing and impact without the void space of a box. The flat-pack format collapses for storage, taking up a fraction of the space of a box equivalent.

Available in 2 products across over 5 sizes. Used for books, magazines, catalogues, DVDs, calendars, documents and any flat media item where rigid protection is needed but a full box is impractical.

Book Wrap vs Standard Box — When to Choose Each

• Book wrap mailers — better for flat, uniform items (books, magazines, prints): self-sizes to contents, no void fill needed, flat-pack storage, lighter weight.
• Cardboard boxes — better for irregular shapes, multiple items or fragile goods needing void fill to prevent movement.

What Size Book Wrap Do I Need?

• A5 paperback (148 x 210mm) — use a book wrap mailer with internal dimensions at least 155 x 220mm.
• A4 document or hardback (210 x 297mm) — use a mailer with internal dimensions at least 220 x 310mm.
• Large format (A3+) — larger board mailers are available for oversized prints, calendars and magazines.

Frequently Asked Questions

What are book wrap mailers used for?
Book wrap mailers are used for books, magazines, DVDs, catalogues, calendars, documents, flat artwork and any media item requiring rigid postal protection. They are the standard dispatch format for book retailers, publishers, direct mail and media e-commerce, providing board rigidity without the cost or bulk of a full box.

Are book wrap mailers recyclable?
Yes — book wrap mailers are made from solid board and are fully recyclable through standard kerbside paper and card collection. There are no plastic components in a standard board book wrap. This makes them a more sustainable dispatch option than bubble mailers for flat media items.

Are book wrap mailers Royal Mail compatible?
Yes. Book wrap mailers are accepted by Royal Mail and most couriers as standard items. Smaller book wraps with lightweight contents may qualify for Royal Mail Large Letter (maximum 353 x 250mm, 25mm depth, 750g). Most filled book wraps will fall into Small Parcel — weigh the packed item to confirm the correct postage band.

How do book wrap mailers work?
Book wrap mailers are supplied flat-packed. Place your item in the centre of the flat board. Fold the side panels up and over the item — the construction self-adjusts to the depth of the contents. A peel & seal strip on the closing flap secures the mailer. No tape, glue or equipment required.
