C6 Board Envelopes

C6 Cardboard Envelopes are perfect for those in need of safely sending flat A6 sized items through the post. Our range of C6 cardboard envelopes comprises the classic board backed envelopes which combine a strong paper front with rigid board backing to give a lightweight mailer whilst ensuring your items don’t bend during transit.  These C6 cardboard envelopes come with a peel and seal adhesive strip to make a secure closure and mean there’s no need for extra adhesives. Available in white, manilla, and smart and sleek black, our C6 cardboard envelopes are the perfect choice for offices and eCommerce businesses alike.  Supplied in boxes for easy handling and neat storage.

Please note: C6 sizing is 114 x 162mm, designed to fit A6 sized items of 105 x 148mm.
