“…This technique is more decisive when differentiating between HDPE, LDPE and mixture. Commercial high density polyethylene may have melting temperatures between 120-130 °C, but in most cases the values are closer to 130 °C or even higher, such as those obtained by some authors and in the analyses carried out in this paper [19][20][21]. On the other hand, the melting temperature of low-density polyethylene is usually between 115 -125 °C, but it can vary above or below these values, since other authors have obtained melting temperatures of 113 °C or 127 °C [22][23][24].…”

Increasing world plastic production generates million tonnes of waste. Flexible packaging bags specially suppose a challenge in mechanical recycling because of their singular properties. This research aims to provide a physicalchemical characterization of commercial polyethylene bags in order to facilitate a future improvement or adaptation of recycling processes to them. Firstly, properties such as dimensions and density were measured in regular and garbage bags samples purchased in different establishments of Granada (Spain). Then, a chemical classification in three groups (HDPE, LDPE, mixture) was achieved according to Fourier Transform Infrared Spectroscopy (FTIR) and Differential Scanning Calorimetry (DSC) tests. Finally, ash content was also determined.

The effect of nanoclay contents on the physical and mechanical properties of bagasse flour/ reprocessed high density polyethylene (rHDPE)/ nanoclay composites was investigated. The bagasse flour content was constant at 50%, the maleic anhydride content was constant at 3%, and the nanoclay (Cloisite 30B) content was set at three different levels: 0%, 2%, and 4%. The materials were mixed in a co-rotating twin-screw extruder; afterwards, the specimens were fabricated using an injection molding method. The water absorption and mechanical properties, such as flexural and tensile strength, flexural and tensile modulus, and notched impact strength, were measured. The nanoclay dispersion was examined by X-ray diffraction. The results indicated that tensile and flexural modulus increased with an increase in nanoclay content. Also By increasing the nanoclay content at 2 wt.%, the tensile and flexural strengths of the composite were increased. However, the addition of 4 wt.% nanoclay resulted in reductions of these properties. Water absorption decreased with increasing nanoclay content. The structural examination of the bagasse polymer composite with X-ray diffraction showed that the nanoclay was distributed as an intercalated structure in the polymer matrix, and the d-spacing of layers decreased with increasing nanoclay content. Scanning electron microscopy (SEM) showed that 2% nanoclay samples with lower and more uniform pores compared at 4% nanoclay samples, respectively.
