Mettler Office Couvert ohne Fenster C4

A seal-like adhesive closure reliably seals the envelope, protecting its contents from unauthorized access. The protective strip ensures that the adhesive maintains its function over a long period, allowing you to rely on its lasting readiness for use. The opaque paper also supports privacy and contributes to environmental protection. It is FSC® certified, meaning it is made exclusively from wood sourced from sustainable forestry, and it is certified with the Blue Angel. The C4 envelopes impress with their efficiency in processing as well as in flexo and offset printing. Additionally, they are resistant to temperatures of up to 140 °C. 120 g Blue Angel, nautilus classic.
