C6 White Board Backed Envelopes

C6 White Board Backed Envelopes are perfect for sending A6 sized important documents, photographs, or prints in the post, keeping them flat, and ensuring they arrive in perfect condition with your customer. Our C6 white board backed envelopes have a strong 120gsm white plain paper front to keep your mail lightweight and not add to your postal costs, due to being sized to comply with Royal Mail Letter sizing, and a 1000-micron rigid backing board to ensure your items don’t bend. A peel and seal adhesive strip closure makes packing fast and gives a strong and reliable seal with no need for additional adhesives. These C6 white board backed envelopes are a super eco-friendly solution; completely plastic free, fully recyclable and biodegradable. Supplied in boxes for easy handling and neat storage.
