Recycling of Polymer-Based Multilayer Packaging: A Review

Abstract:Polymer-based multilayer packaging materials are commonly used in order to combine the respective performance of different polymers. By this approach, the tailored functionality of packaging concepts is created to sufficiently protect sensitive food products and thus obtain extended shelf life. However, because of their poor recyclability, most multilayers are usually incinerated or landfilled, counteracting the efforts towards a circular economy and crude oil independency. This review depicts the current state of the European multilayer packaging market and sketches the current end-of-life situation of postconsumer multilayer packaging waste in Germany. In the main section, a general overview of the state of research about material recycling of different multilayer packaging systems is provided. It is divided into two subsections, whereby one describes methods to achieve a separation of the different components, either by delamination or the selective dissolution-reprecipitation technique, and the other describes methods to achieve recycling by compatibilization of nonmiscible polymer types. While compatibilization methods and the technique of dissolution-reprecipitation are already extensively studied, the delamination of packaging has not been investigated systematically. All the presented options are able to recycle multilayer packaging, but also have drawbacks like a limited scope or a high expenditure of energy.

“…This can be attributed to the fact that 5 wt% EMA-GMA has not been sufficient to produce the necessary reactions. Chen 28 showed, by means of FTIR analysis, the presence of reaction between end groups of -COOH or -OH of rPET chain and the epoxy group of E-GMA, observed from the decrease in intensity or disappearance of the E-GMA epoxy peak.…”

This study evaluated the effect of adding poly (ethylene methyl acrylate) (EMA) and cotton linter (CL) on the properties of recycled poly (ethylene terephthalate) (PET rec ). For this, PET rec /EMA blend and PET rec /EMA/CL composite were developed. In order to improve the interfacial adhesion and the properties of these materials, ethylene/methyl acrylate/glycidyl methacrylate terpolymer (EMA-GMA) and polyethylene-grafted maleic anhydride (PE-g-MAH) were added. The rheological results showed that the addition of EMA increased and the addition of 1 wt% of CL reduced the viscosity. The morphological analysis of the non-compatibilized blend and composite showed poor interfacial adhesion. Polymer blends with 2 and 6 wt% of EMA had better mechanical properties, since these formulations have the smallest average particle diameter of 0.58 and 1.00 µm, respectively. The mechanical testing of composites showed a material with higher maximum strength and elasticity modulus than polymer blend when analyzed at the same EMA phase concentration. The use of EMA-GMA was effective in reducing the size of particles of the EMA in the blend.

“…The rHDPE/rPET weight ratio used was 75/25 (w/w) and 5 wt.% EGMA, based on the weight of rHDPE and rPET added to the matrix. This matrix composition was chosen from the authors' previous study (Chen et al 2014). As shown in Fig.…”

“…Using PCR such as recycled polyethylene (PE), polypropylene (PP), and PET, the use of virgin plastic could be eliminated, one potential solution to the problem of waste plastic pollution. PCR polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET) account for a large amount of all waste plastic materials (Chen et al 2014;2015c). Many studies have been conducted on the preparation and characterisation of natural fibre composites based on PCR plastics (Lei et al 2009;Fávaro et al 2010).…”

Biocomposites were prepared with rice husk flour (RHF) (raw and alkalitreated) in a recycled polymer blend (RPB) using a co-rotating twin screw extruder. Modifications to the composite were carried out through fibre surface treatment with 4 wt.% sodium hydroxide (NaOH) and 3 wt.% maleic anhydride polyethylene (MAPE) coupling agent. Fourier transform infrared (FTIR) analyses of raw and NaOH-treated RHF were performed. The effects of the interfacial modification (MAPE or/and NaOH) and filler loading (50 to 80 wt.%) on the mechanical, physical, and morphological properties were investigated. Improvements in the tensile strength and Young's modulus as well as reduction in water absorption and water loss were observed for raw RHF composites incorporated with MAPE. Alkalisation of fibres resulted only in an enhancement in elongation and impact strength. The composite with 70 wt.% RHF modified with only MAPE exhibited the highest tensile strength and modulus, 22.2 and 711.6 MPa, respectively. The general trend of the composite results exhibited some decrease in water absorption and water loss from untreated RHF composites with only MAPE modification as compared to the NaOHtreated composite, although a rougher surface for the treated fibres was revealed in SEM images.
