Each day it’s carelessly torn up and thrown away only to be found anew and intact in our letterboxes the following day: The envelope. This reliable part of our day most likely also means a reliance on the companies that comprise the Mayer-Kuvert-network, producing more than 20billion envelopes each year – approximately every fourth envelope sent from Europe. Mayer-Kuvert-network offers a variety of standard sized envelopes, padded mailers and shipping envelopes. One star product is the Envirelope® produced in Heilbronn. Envirelope® products are manufactured with bright white carbon neutral paper and also feature biodegradable plastic windows, water-soluble glues, and fully deinkable interior ink that guarantees one hundred percent recyclability.
