Combine efficient office workflows with high-quality recycled materials. The Elco Proclima series sets the standard for business correspondence: These high-quality recycled envelopes in DIN Long+ (C6/5) size are not only made from 100% FSC-certified recycled paper, but also feature a window made of window film.
Despite the high recycled content, you don’t have to compromise on appearance. The paper is bright white and looks just like conventional white envelopes. The convenient window on the left side also saves you valuable time when addressing your business mail. Be sure to check out our selection of DIN Lang+ envelopes without windows to find the right option for you.
These mailing envelopes are manufactured in Switzerland. Every detail has been carefully considered—even the opaque interior printing is done with solvent-free water-based ink. Thanks to their high functionality, these envelopes are indispensable for modern office supplies.
At Kuvertwelt, you’ll benefit from attractive volume discounts: The more window envelopes you need, the lower the unit price becomes. Order your Elco Proclima envelopes by the piece or in bulk.
