Mechanical recycling of polyamides in multilayer film structures

BASF welcomes reclassification of recyclability of coextruded polyethylene/polyamide film structures


The „Stiftung Zentrale Stelle Verpackungsregister” (Central Agency Packaging Register) has reclassified the recyclability of polyamides in the minimum standard for assessing the recyclability of packaging subject to system participation pursuant to Section 21 (3) VerpackG: Since September 1, coextruded polyethylene (PE)/polyamide (PA) film structures have been recognized as mechanically recyclable.

Institute cyclos-HTP GmbH has proven and certified the recyclability of polyamide 6 (PA6, Ultramid® B) as well as Polyamide 6/6.6 (PA6/6.6, Ultramid® C) in coextruded polyethylene (PE)/PA6-multilayer film structures for the PE film stream. This was analyzed for PA contents of up to 30 percent in the original packaging based practice-relevant conditions.

The research details and results related to this work have been summarized in an updated publication to provide detailed answers to a wide range of questions on this issue. This publication is available for download here.


“Film-to-film” approach for PE/PA waste blends is a real recycling option including manufacturing of  “new” monolayer films:
