Ultimate Protection for A4 Books & Documents The C-A4 book wrap, also known as CPF005, is built for A4-size books, manuals, and documents, at 303 x 215mm with a variable depth of up to 77mm to handle thicker items without wasted space. Made from 100% recycled corrugated board, with impact-buffer edges and strengthened corners, it's built to withstand the knocks and pressure of transit without denting or crushing its contents. Every C-A4 wrap uses our twin peel & seal system with a tear-strip, keeping internal flaps securely fastened during transit while remaining easy for your customer to open. The hot melt adhesive offers 300x the tack of standard tape and peels 90% faster, thanks to its fast-release paper. A close, accurate fit also works in your favour on postage: less wasted space per item means more units per pallet, cutting transport costs alongside your mailing costs — and since it's compliant with Royal Mail's small parcel tariff, you're not overpaying to post it either. Need to order in volume without a storage headache? We hold large quantities of C-A4 book wraps in stock, ready to ship. See our full range of Book Wraps in all sizes.
