BASF, in collaboration with the cyclos-HTP Institute, has jointly published new insights into the mechanical recycling of polyamide-containing co-extruded flexible packaging films (PE/PA multilayer film.
As an independent testing and certification body, cyclos HTP, on behalf of BASF, systematically investigated the recyclability of PE/PA multilayer films and confirmed its results in 202 The conclusions of these investigations are now available in a 25-page publication on the BASF and cyclos HTP websit.
In tests, coextruded PE/PA multilayer films with PA6 and PA6/6 concentrations up to 30% were used with tie layer materia.
In addition, the cyclos HTP Institute used these latest results to differentially certify the recyclability of individual flexible PE/PA packaging structures through a case-by-case revi.
An excerpt from the publication states, “Because the recyclability classification of packaging materials is closely linked to political and economic interests, it is not only impossible to take a holistic approach to assessing the advantages and disadvantages of individual polymers and related packaging solutions while considering practical constrain.
