When do you need gusset envelopes B4?
Gusset envelopes are indispensable for sending documents that you do not want to fold, such as contracts, certificates or A4-size prints. The B4 format offers sufficient space for A4 documents without them becoming creased during transport. You choose this type of envelope when you regularly send important papers that must arrive in perfect condition.

Why choose the variant without a window?
These envelopes without a window give you complete freedom in addressing. You can write the address by hand, stick on a label or print it directly onto the envelope. This is ideal when you send different types of post or when the layout of your documents is not suitable for window envelopes.

Reinforced construction for heavier use
With a paper weight of 140 g/m², these envelopes are sturdier than standard post. The 20 mm gusset and Klotzboden (reinforced base) ensure that the envelope retains its shape, even when sending several sheets of paper or lightweight cardboard documents. This construction prevents tearing during transport.

Practical tips for use
The Haftklebung (self-adhesive closure) makes wetting by hand unnecessary – you simply peel off the protective strip and press the flap down. The white colour gives a professional appearance suitable for business correspondence. With 100 pieces per pack, you have sufficient stock for regular use without needing a lot of storage space.
