1. Convenient Loading on the Long Edge

Unlike standard envelopes, this model features a flap along the long (324 mm) side. This significantly facilitates document insertion:

• Compatibility: The bright white surface is perfect for handwriting addresses or applying printed labels.

Frequently Asked Questions (FAQ)

Is this envelope suitable for sending A4 contracts?

Yes, the C4 format is specifically designed for A4 sheets (210x297 mm) so they fit without any folding.

What is the advantage of a long-edge opening?

It allows for easier and safer insertion of multiple sheets because the opening is wider than a standard envelope that opens on the short edge.

Can these envelopes be used in printers?

While theoretically possible, we recommend printing addresses on labels, as the peel & seal strip and adhesive layer may be sensitive to the heat of laser printers.
