White board backed envelopes are a reliable mailing solution for safely sending a large range of items and ensuring they’re kept flat whilst in the post. These white board backed envelopes combine a robust 1000-micron board backing to ensure your important documents don’t bend in transit, and a smart and strong 120gsm white paper front to keep your postal costs low. Available in a wide range of sizes both with and without printing, these white Do Not Bend envelopes are an eco-friendly mailing envelope which are recyclable and biodegradable. All sizes of our white board backed envelopes have a peel and seal adhesive strip closure to give a secure seal which requires no additional adhesives. Supplied in boxes for minimal storage requirements and easy handling.
