“…The results of the presented research do not differ from the results of the work carried out so far, including PET-based blends [21,38,39]. Apart from the impact modifiers used in other works, which are sometimes compounds based on styrene or acrylic copolymers [40,41], the convergence with the results obtained for the POE-g-GMA copolymer is still very high.…”

This research aimed to evaluate the material properties of reactive extrusion-modified blends containing PET multilayered foil waste. Three types of PET-based multilayer foil waste were used as the compound during the reprocessing of standard bottle-grade PET. Flakes used for this purpose were made from laminated foils: (A) PET/PE, (B) PET/EVOH/PE, and PET/PE/met. All types of the prepared materials were compounded with 30% of the waste foil flakes. Additionally, the blend was modified with an epoxy-based chain extender and polyolefin-based impact modifier. The prepared blends were processed using two methods; initially, the materials were prepared by injection molding, while cast-film samples were also prepared. All samples were subjected to full characterization using mechanical testing methods, thermal analysis, and structural observations. The study shows that the addition of multilayered foil waste is leading to significant deterioration of PET-based material properties. While, in most cases, the use of a chain extender led to some improvement in mechanical characteristics, the impact modifier addition strongly influenced most of the properties. It was also observed that the reactive extrusion procedure led to melt strength improvement, which greatly facilitates the film production process. Due to the limited possibility of separating the film components, the developed method of foil recycling might be useful for the utilization of multilayered packaging.

Degradation, a common problem faced during the processing of recycled poly(ethylene terephthalate) (PET), leads to significant embrittlement of the products, as a result of which the material loses its applicability. Increased crystallization rate of the short chains of recycled PET and obstructed mobility of the amorphous phase are the main causes of enhanced brittleness. In this research, a straightforward method is proposed for improving the toughness of recycled PET products, namely the devitrification of the rigid amorphous phase by thermal annealing, which results in enhanced molecular mobility in the amorphous fraction, thereby promoting ductile deformation. The effects of thermal annealing conditions are comprehensively evaluated on the microstructure and macroscopic properties, i.e., impact resistance, of recycled PET films. The perforation energy value of the recycled PET film is found to increase to its threefold, reaching a value higher than 18 J mm−1, as a result of 10 s thermal treatment at 120 °C. Differential scanning calorimetry, dynamic mechanical analyses, and thermally stimulated depolarization current measurements provide evidence for the devitrification of the rigid amorphous fraction under these conditions, which is the key to efficient enhancement in toughness.

Pollution from plastics is a major issue in the current context, prompting the scientific community to focus its efforts on recycling these materials. Mechanical recycling emerges as the most popular due to its practicality and cost‐effectiveness. In fact, with the increase in environmental awareness, the adoption of new circular economy models, stricter regulations mandating disposal and recycling, and lower costs compared to other recycling techniques, this type of recycling is taking a predominant role over other method. However, the presence of a variety of products of different polymeric nature, the introduction of new biodegradable products, and the complexity of multilayer packaging combining different polymers, without concrete solutions for recycling create a heterogeneous range of materials that leaks into the environment. The scientific literature is actively addressing these challenges, and this review aims to explore the latest strategies for enhancing the mechanical recycling of new and challenging polymer systems. Specifically, it explores the recycling of materials originally designated for landfill, incineration or composting, focusing on advancements in management of these previously overlooked and problematic system. This underexplored perspective seeks to offer new insights and innovative solutions that can transform polymer waste management and advance more sustainable recycling practices.
