C4 window left; self-adhesive
C4 envelopes with dimensions 229 x 324 mm are used for documents in DIN A4 format that should not be folded, such as certificates, diplomas, contracts, and other official documents. Thanks to the film window made of recyclable parchment, you save an additional step, as the recipient's address, already printed on the document, automatically appears in the film window – we call this efficient mail delivery. Other advantages include laser compatibility (up to 140°C) and the proven self-adhesive closure that acts like a seal. It's best to stock up on these envelopes. The self-adhesive remains functional for a long time, as a protective strip reliably prevents drying out.
