“…Postindustrial polymeric waste used in this study was kindly supplied by Valfilm Ltda as scrap from production by extrusion molding of low‐density polyethylene film (LDPE) and LDPE/PA6 multilayer films, containing around 78 wt % of LDPE and 22 wt % of PA6, respectively . Virgin polyamide (PA6), the compatibilizer PE‐ g ‐MA Amplify TY‐1353 and the thermal stabilizer SONGNOX 21B FF were also donated in the granule form (pellets).…”

Multilayer films combine properties of different polymers in a single material, attending specifications to applications such as packaging. However, the mechanical recycling for this material king is commercially less interesting because the polymeric components cannot easily be separated and the direct mechanical processing of the material leads to the immiscible and incompatible polymeric blends. The aim of this study was to evaluate properties of the blends of low‐density polyethylene (LDPE) and polyamide 6 (PA6) generated from mechanical recycling of multilayer films constituted by LDPE and PA6, containing maleic anhydride grafted polyethylene (PE‐g‐MA) as compatibilizing agent and different amounts of virgin PA6. The LDPE/PA6 blends are immiscible for all composition and the use of PE‐g‐MA has showed little effect on the compatibility of the blends with high content of PA6. However, LDPE/PA6 blends with PA6 content up to 20 wt % showed considerable performance for mechanical performance that can justify the mechanical recycling of the material. © 2019 Wiley Periodicals, Inc.

“…Moreover, various components of the laminate can be disturbing or even detrimental during the recycling process itself like the presence of polyvinylidene chloride (PVdC) or aluminium [11]. Although there is scientific knowledge on the compatibilisation of immiscible polymer blends there is little scientific information on the recyclability of laminates [12][13][14][15][16]. Moreover, an integrated analysis of the recycling of laminates should also encompass the current and future waste management systems that include disposal by civilians, collection systems, sorting processes and recycling processes (mechanical, chemical, organic, thermal).…”

This report focusses on flexible laminated packages that are composed out of multiple polymer types and their impact on the recycling chains. Approximately 3-4% of the packaging products used in Europe is a laminated flexible packaging film. By nature, these films are either more difficult to recycle than mono-material packaging products, or even impossible to recycle.In the Netherlands roughly 65% of the laminated flexibles are discarded with the mixed municipal solid waste and 35% are collected in separate collection schemes for lightweight packaging wastes.After sorting the laminates are distributed over the various sorted products; roughly 60% ends up in the sorted product MIX, 25% in the sorted product FILM, 10% in the various sorting residues and 5% in valuable sorting products like PP and PE where they may hinder recycling of these valuable sorting products. Current and future options for the waste management of multi-material laminated flexible packaging films include mechanical-, chemical-and organic recycling. Next to technical feasibility and technical hurdles there are various practical and economical limitations and acceptance issues that presently limit recycling of flexible laminates. Most stakeholders involved in plastic packaging are committed to develop a more sustainable, circular plastics industry. Despite the willingness of industry to move to sustainable and recyclable packaging products there are numerous challenges with respect to flexible laminates for packaging applications. Strategies to improve the end-of-life options for flexible laminates can be categorised in four main categories; avoid the use of laminates, redesign the laminates, redesign the collection & recycling scheme or improve the sort-ability and recognisability. As a first step (agreement on) a precise definition of recyclability is needed to allow evaluation of the recyclability of laminated flexible packages. This implies that a test method is needed to verify if newly developed laminated flexibles are recyclable 6 | Public Wageningen Food & Biobased Research-Report 2037

In this article, we discuss the radiation effects and ethylene‐vinyl acetate (EVA) as compatibilizing agent on waste polyethylene (WPE)/virgin polyethylene (VPE), 80/20 wt%, reinforced by Kevlar fiber (Aramid). Hence, by melt mixing the compatibility between WPE and VPE will be performed by adding 10 phr fixed weight of EVA. After that various weights of Kevlar fiber at phr 1.5, 2.5, and 3.5 were reinforced into prepared polymer blend. The composites mechanical properties and the thermal stability were predicted. Furthermore, infrared and X‐ray diffraction used to characterize the composites structure. Improvements of both tensile strength and elastic modulus of prepared composites at 1.5 phr of Kevlar was observed and decreased in their values were noticed after that. Also, thermal stability has been enhanced with EVA and Kevlar fiber. Remarked improvements in studied parameters were generally determined by formation of crosslinking networks via gamma irradiation.
