Indestructible Protection for Your Biggest Shipments The C6 is our largest book wrap sized at 540 x 330mm with a variable depth of up to 140mm. This mailer is built for items too big or bulky for anything else in the range, such as oversized books, games consoles, and gift sets, as well as toys, puzzles, picture frames, and photo albums. Made from B-Flute corrugated board, with impact-buffer edges and strengthened, glued corners, it's built to handle the heaviest, bulkiest items in our range without denting or crushing their contents in transit. Every C6 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.
