A new publication by BASF and institute cyclos-HTP reveals insight into the mechanical recycling of PE/PA multilayer films.
In June 2021, the independent testing and certification body, cyclos-HTP systematically investigated the recyclability of PE/PA multilayer films on behalf of BASF. In the tests, co-extruded PE/PA multilayer films with PA6 and PA6/6.6 concentrations of up to 30% were used with tie layer materials. Based on the established CHI standard, cyclos-HTP tested the recycling compatibility and recyclability of these films in the PE film stream from commercial sorting processes for household flexible plastic packaging waste.
Results drive differentiated certification
cyclos-HTP is already using these updated results for the differentiated certification of the recyclability of individual flexible PE/PA packaging structures. This is done by performing case-by-case reviews of packaging structures that were previously classified as incompatible for recycling (according to section 4.3 of the minimum standard for determining the recyclability of packaging subject to system participation pursuant to section 21 (3) VerpackG, Central Agency Packaging Register, 2021).
