Ultimate Protection for Larger Books & Gifts The C4 book wrap is built for items too large for standard A4 packaging, oversized hardbacks, cookbooks, and 12x10 photo frames, as well as board games, gift sets, and multi-book bundles, at 326 x 280mm with a variable depth of up to 70mm. Made from Kraft corrugated cardboard, with impact-buffer edges and strengthened, glued corners, it's built to get bulkier, heavier items through the postal system without denting or crushing their contents. Every C4 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, up to 60% more, in fact, cutting transport costs alongside your mailing costs. Need to order in volume without a storage headache? We hold large quantities of C4 book wraps in stock, ready to ship. For more on shipping books and similar items safely, see our ecommerce book packaging guide, or browse our full range of Book Wraps in all sizes. If you're looking for a size that qualifies for Royal Mail's letterbox-friendly large letter tariff instead, our guide to the maths behind large letter tariffs explains how sizing affects postage cost, and our C3, C-A4, and C-COM wraps are designed with that tariff in mind.
