The French Post Office introduced pre-stamped envelopes made of DuPont™ Tyvek® brand protective material with a special ‘track and trace’ system in 1989. These easy-to-store, easy-to-use envelopes offer multiple benefits to converters, the Postal Service and end users alike.
For end users, pre-stamped envelopes offer one-stop shopping and safe delivery of important contents.
For converters, the pre-stamped envelopes are a high-value offering that can be printed on both flexographic or offset litho printing processes.
For the Postal Service, pre-stamped envelopes offer assured protection of customer contents which translates to a reduced likelihood of claims; they can reduce volume requirements due to the flexibility and conformability of the DuPont™ Tyvek® envelope; they project a high-quality image; and they are readily recyclable.
