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.

Barriers

Best Before

Packaging protects goods against external influences. But some products need more protection than standard plastic is capable of offering. In those cases, there are various options that allow special plastics and coatings with a barrier effect to be integrated into the packaging itself. These additives have essentially no impact on the recyclability of the packaging.

MBT

A special barrier layer made from a material like EVOH or PA is embedded within a standard plastic. This produces a gas barrier that gives the packaged product special protection against external influences. MBT is suitable for a broad spectrum of packaging solutions.

IBT

A barrier layer made of silicon oxide is applied to the inside and outside of a plastic cup. This layer protects the packaged product against external influences, giving it an especially long shelf life. It doesn’t have any impact on the recyclability of the plastic cup. Greiner Packaging is a global market leader in the application of IBT.

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!
