The swap that looks close
a deep box is the usual substitute for book wraps, and it is the wrong one. A deep box around a book adds fill and can push you into a larger postal format.
Packaging Boxes lists Book wraps separately because the jobs diverge as soon as the goods are on the bench.
What the right line actually does
Book wraps are the flat pack for a book or a slim parcel.
They are described as 100% recycled E-flute, biodegradable and recyclable, with a peel-and-seal strip.
If you have already mixed them
Forcing a thick item into a wrap bursts the seam.
A Packaging Boxes basket with Book wraps still leaves the same day if it is placed by 3pm. The terms aim for 5.30pm the next working day. A 1 to 3 day courier is also described, depending on the lines.
Open Book wraps when you already know this line. Read the pack count. Packaging Boxes will still dispatch an order placed by 3pm on the same day.
