The envelope, please: Sustainability fuels e-commerce mailer innovation

You’ve got mail — or rather, e-commerce deliveries. And it’s increasingly likely that those products could arrive in a mailer instead of a box.

Mailers are having a moment amid market evolutions and shape, size and reuse innovations. While the e-commerce surge has helped this packaging format gain prominence, sustainability aspirations such as substrate switches and material reduction are taking demand to the next level. 

Whatever the reasons, mailer manufacturers are riding the wave and chipping away at corrugated boxes’ stronghold as the most used packaging format. Ryan Fox, corrugated packaging market analyst at Bloomberg Intelligence, has noted a recent “acceleration” of paper mailer use and projected it would further eat into corrugated box volumes in 2026. Others agree with the magnitude of the movement.
