r-PET: the front-runner
Strong availability, food-grade status, and high quality are the properties that make r-PET the top material when it comes to sustainable packaging. Greiner Packaging is working continuously to optimize the material itself as well as driving the methods used for processing it.
Benefits of r-PET:
Thanks to the high transparency of r-PET, consumers can already convince themselves of the freshness of the packaged food on the supermarket shelf.
r-PET is readily available both in Europe and internationally. Greiner Packaging customers benefit from the recycled material of Greiner Recycling.
r-PET is granted a positive EFSA-opinion and can therefore be used as (almost) the only mechanically recycled material for food applications.
Thanks to its good barrier properties, r-PET protects products particularly well from external influences, such as oxygen or light.
Even products with a high fat content can be safely packaged in r-PET.

Today, food-grade r-PET is produced almost exclusively from bottle streams. However, if the material is used to make items such as cups and blister packs, there is currently only a limited opportunity to recycle it again. That must change in the future, with the aim to establish a so-called tray-to-tray recycling stream. Many projects already exist that drive such streams.
Another challenge is that, in comparison to other materials such as PS or PP, conventional (r-) PET shows lower heat resistance. For products that require heat resistance (r-) PET HTS® will be an interesting option in the future.
