Our board back envelopes are a great and affordable way to protect your important documents whilst in the post. Made from a quality 120 GSM paper on one side, usually printed 'Please do not bend' and backed by a rigid 500/600gsm, 1000 micron board to ensure that your important item arrives safe and uncreased.
Available in a variety of popular colours and sizes including C5 and C4, our boardback envelopes, sometimes known as hard back or 'Please do not bed' envelopes, are often used by many major mailing companies to send out important documents, passports, and photography due to their protective nature.
