C4 White Board Backed Envelopes are the perfect choice for sending A4 sized important documents or photographs through the post whilst ensuring they’re kept flat during transit. Our C4 white board backed envelopes have a 1000-micron rigid backing board to ensure your items don’t bend, and a high quality 120gsm white plain paper front to keep your mail lightweight and not add to your postal costs. Our range includes plain, with and without a window, as well as printed 'Please Do Not Bend' depending on your requirements. A peel and seal adhesive strip closure makes packing fast and gives a strong and reliable seal with no need for additional adhesives. Our C4 white board backed envelopes are an eco-friendly solution; completely plastic free, fully recyclable and biodegradable. Supplied in boxes for easy handling and neat storage.
Please note: C4 size is up to 229 x 324mm, designed to fit A4 sized items of 210 x 297mm.
