Rigid Card Envelopes
Looking for a strong envelope to post and protect your book, brochure or calender? Then our Rigid Cardboard Envelopes are an ideal choice. Made from high quality, strong 300gsm or 400gsm card in natural manilla brown, these envelopes are sometimes called Capacity Book Mailers or Card Mailers. They are designed to encase items with depth to them, that wouldn't fit or be protected by a regular paper envelope. This is why they are ideal for posting books and brochures. Think of the items you may receive in the post from stores such as Amazon - these often arrive in Rigid Card Envelopes / Capacity Book Mailers the same as these. With a handy peel & seal closure, they are easy to fasten for the sender. And for the receiver of the envelope, they have a handy rip & strip open, making the envelope easy to get into.
