C5 Board Backed Envelopes are specifically designed for sending important A5 sized important documents which have to remain flat during transit. These A5 do not bend envelopes are constructed from a rigid backing board and combine with a paper front to keep your mail lightweight, making your postal costs minimal, and providing excellent protection to your thin items. The peel and seal adhesive strip closure ensures quick and easy packing for you, making a secure seal which eliminates the need for any extra adhesives. Available in smart black, plain and printed white, or manilla with printed do not bend - all are an eco-friendly solution; recyclable, biodegradable, and plastic free. Packed in boxes for easy storage and neat organisation.
Please note: C5 size is up to 162 x 229mm, designed to fit A5 sized items of 148 x 210mm.
