When do you need back-board envelopes?
Cardboard back-board envelopes are used for safely sending important documents that must not be folded or creased. Thanks to the sturdy cardboard backing, A4 documents, photos, certificates and contracts stay perfectly flat during transit. These B4 envelopes offer enough room for standard A4 paper without having to fold the contents.

Why choose the B4 format?
The B4 format is specifically designed for A4 documents and provides just enough extra space around your papers. This means you can slip A4 sheets into the envelope without them getting stuck or damaged. The brown colour gives a professional appearance and is less prone to showing marks than white envelopes.

Reliable adhesive strip with protective film
These back-board envelopes feature a peel-and-seal adhesive strip with a release liner that ensures a strong and reliable seal. Simply peel off the protective strip and press the flap down - no water or saliva needed. The adhesive is strong enough to keep the envelope securely closed, even with heavier paper.

Practical stock pack of 100 pieces
With 100 envelopes per pack, you have plenty of stock for regular use. The paper weight of 130 g/m² provides sturdiness without making the envelopes too thick for standard postal processing. Store the envelopes dry and flat to prevent warping and to keep the adhesive strip in optimal condition.
