When do you need sturdy cardboard envelopes?
These MAILmedia cardboard envelopes in B4 format are ideal for sending documents that need extra protection. Use them when ordinary paper envelopes are too thin, for example for sending photos, certificates, contracts or other valuable papers that must not be folded or damaged during transport.

Why choose B4 format without a window?
The B4 format offers enough space for A4 documents without having to fold them. Because there is no window, you have complete privacy - the contents remain fully hidden, and you can write the address anywhere on the envelope or stick on a label wherever suits you best.

Sturdy construction in natural cardboard
These envelopes are made from 120 g/m² natural cardboard (Natron), which provides robust protection for your documents. The material is considerably sturdier than standard envelopes and holds its shape well, even with rougher handling during transport. The natural cardboard material also gives a professional look.

Practical packaging with self-adhesive closure
With 125 pieces per box, you have enough stock for regular use. The envelopes are fitted with a Haftklebung - a self-adhesive strip that you activate simply by peeling off the protective layer. This is quicker and more reliable than moistening traditional glue, especially handy when you need to seal several envelopes one after another.
