The CEFLEX initiative brings together more than 180 European companies, associations and organizations that represent the entire value chain of flexible packaging. To help boost recycling rates and expand sustainable end markets, a team of CEFLEX stakeholders developed a Quality Recycling Process (QRP).
The scope of QRP is to mechanically recycle a higher percentage of PE (polyethylene) and PP than currently done for non-food contact film applications, since flexible packaging from household waste has very low recycling rates in Europe. After five semi-industrial trials, the final objective is to now build an industrial scale QRP waste processing demonstration plant that will run commercially by 2023.
The trials show that flexible packaging waste can indeed be sorted and recycled into fractions that can be made into resins to produce film destined to non-food packaging applications. This can include household cleaning products, like dishwasher tablets.
What about the performance of the film during printing, converting through to the end product displayed at the point of sale? To test and prove the validity of the concept of using recycled polymers in this respect, collaborative task teams of CEFLEX stakeholder companies were set up to create a set of samples using PE and PP recyclates printed with CEFLEX artwork for different applications, for example, stand-up pouches, labels and shrink sleeves.
Bobst has taken part in a trial to develop CEFLEX stand-up pouches. The coating, laminating, printing, and vacuum metalization steps were carried out in its Competence Centers in Italy, Germany, and the UK. Other partners in the pouch making trials were Taghleef Industries for the rPP film, Borealis for the sealant film, Coim, Henkel and Sun Chemical for the adhesives, Flint Group for the inks, and Elba for pouch making.
