A bigger single wall box is not a stronger box. This page stays with book wraps, next to Royal Mail large letter boxes.
Packaging Boxes keeps Book wraps apart from a deep box. They are described as 100% recycled E-flute, biodegradable and recyclable, with a peel-and-seal strip.
What this collects
Book wraps are the flat pack for a book or a slim parcel.
Royal Mail large letter boxes is the neighbour on this list. Large letter boxes are for the large-letter format, not for a small parcel that happens to be flat. It is still a different range from book wraps.
Before the order goes in
Set the wrap to the book’s depth. If it will not close without force, the book wants a different pack.
On Packaging Boxes, put Book wraps on the order with the lines it belongs to, so you are not paying a second delivery for the piece you forgot. Free UK delivery starts over £50 ex VAT.
