Cardboard Envelopes / Book Mailers – A4 / 100 per pack

Our cost-effective cardboard envelopes are the answer when you want to mail flat items – like books – in a strong protective board backed envelope but need extra depth. Sometimes known as “capacity book mailers”, they can adapt to the thickness of the contents by up to 50mm – perfect for also posting DVDs, artwork, computer games and brochures.

Simply pop the item/s inside and close with the secure peel-and-seal strip. You can label or write directly on the smooth Manilla Kraft finish and there is an easy tear-off opener. The cardboard envelopes are Royal Mail large letter size (up to 25mm thick and 750g).

Product Description

These A4 cardboard envelopes are supplied in economical packs of 100 – perfect for online traders, retail and mail order businesses. They need less storage space than bubble bags and provide a low-cost versatile mailing solution with better edge and corner protection than bubble wrap envelopes.

Manufactured from top quality 400gsm cardboard sized 234 x 334 mm, our convenient rigid envelopes / book wraps have a high tack tamperproof peel-and-seal feature and easy open ripper strip. There’s no need for packing tape or additional wrapping, although you could use coloured or white tissue if you wished to prettify the goods inside. Our stiff board envelopes offer an attractive professional postal packaging solution, with a smooth Manilla brown Kraft surface on which you can stick labels or documents enclosed wallets, or just write on directly.

Often referred to as “capacity book mailers”, they have capacity creases which are cleverly designed to allow the cardboard shape to expand to the thickness of the contents (up to 50mm). Obviously, the more the capacity is increased, the less is the envelope’s overall size.

Lightweight but strong, our cardboard envelopes are suitable for book packaging and posting or storing other flat items.
