The Elco Proclima series demonstrates that top-notch quality and recycled materials can go hand in hand. These recycled envelopes in the generous DIN Long+ (C6/5) size are made from 100% FSC-certified recycled paper. What makes them special: Despite their recycled content, the envelopes have a brilliant white finish and are virtually indistinguishable from conventional office supplies made from virgin cellulose.
By using these envelopes, you’re choosing a recycled product without sacrificing the quality you’ve come to expect from a premium product. If you’re looking for a more compact option, we also offer the recycled white C6 envelope from Elco. Alternatively, for automated mailings, we also carry DL+ envelopes with windows.
These mailing envelopes feature the convenient Optifix self-adhesive closure. Simply peel off the protective strip, press lightly, and the envelope is securely sealed—no need to wet it. The gray interior lining not only ensures your documents are completely opaque but also highlights the high-quality origins of the Swiss brand Elco through its subtle branding.
Order your Elco envelopes from us in any quantity, starting with just one, and receive exactly the amount you need for your office or personal correspondence. You can also take advantage of our attractive volume discounts for larger projects.
