C3 Manilla Board Backed Envelopes

C3 Manilla Board Backed Envelopes are an excellent solution for sending A3 sized important documents or flat prints through the post and ensuring they don’t bend whilst in transit. Our C3 manilla board backed envelopes combine a rigid 1000 micron backing board to ensure your items are kept flat, and a strong 120gsm paper front with Please Do Not Bend printed in the bottom left corner for in-transit instructions. A peel and seal adhesive strip closure makes for fast packing and gives a strong and reliable seal with no need for additional adhesives. These C3 manilla board backed envelopes are an excellent eco-friendly solution; completely plastic free, fully recyclable and biodegradable. Supplied in boxes for easy handling and neat storage.

Please note: C3 size is up to 324 x 458mm, designed to fit A3 sized items of 297 x 420mm.
