Sustainability

Join the circular revolution!

Our climate is changing, biodiversity is in decline, we are in the midst of an environmental crisis. As plastics manufacturers, we want to use all the tools at our disposal to protect our world. 

That is why we are committed to reducing what can be avoided (reDUCE), using what can be used again (reUSE), and recycling what cannot be reused (reCYCLE). 

 

All three Rs are important building blocks for the future of packaging.

Often imitated, never equaled!

K3® the original since 1982

What started life 40 years ago in the small town of Diepoldsau in Switzerland has since spread far and wide – it’s now impossible to imagine supermarket shelves around the world being without cardboard-plastic combinations.

As the inventors of K3®, we know the packaging inside out. We have been working with our network of partners for over four decades to keep improving cardboard-plastic combinations, making them even more user-friendly and, crucially, even more environmentally friendly.

Celebrate with us 40 years of innovation!
