Bio- and Fossil-Based Polymeric Blends and Nanocomposites for Packaging: Structure–Property Relationship

“…The progress of scientific investigations on polyethylene/chitosan composites has gained significant consideration, especially those prepared by melt processing, because of their superior control of the final material’s properties with respect of solvent evaporation methods. The result of the work by Lima et al [214] specified that chitosan tunes the viscosity, loss modulus, storage and torque modulus (i.e., melt viscosity), and the mixture chitosan/PE-g-MA compatibilizer has a comparable, even if negligible, consequence. In the case of higher fillers amounts, (more than 15 wt %) the PE-g-MA influenced the rheological behavior of the mixtures, maybe improving matrix–filler interactions and working as an active compatibilizer [215].…”

HDPE/Chitosan Blends Modified with Organobentonite Synthesized with Quaternary Ammonium Salt Impregnated Chitosan

“…Thus, the development of research about blends of chitosan with polyolefins has received considerable attention, especially those that are prepared by melt processing, because of their high yield, and greater control of the final material’s characteristics without atmospheric pollution, in comparison with the solvent evaporation methods [ 12 , 13 , 14 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 ]. However, there are only a few published reports on blends of chitosan with high density polyethylene (HDPE) [ 38 , 39 ], and, to the best of our knowledge, the compatibilization of these blends with organobentonite synthesized with quaternary ammonium salt impregnated chitosan has not been conducted yet.…”

Thermoplastic Recycling: Properties, Modifications, and Applications

“…This might be uneconomical. The enhancement in mechanical properties and performance of the HDPE matrix and composite product by additives (sodium hydroxide (NaOH), sodium lauryl sulfate (SLS), and acetic anhydride) have also been attributed to increased interfacial adhesion coupled with its improved water absorption [21], biodegradability, biocompatibility, antimicrobial activity, and non-toxicity with the use of chitosan compounds [38]. The density of recycled virgin and waste HDPE is within the range of 0.02-0.96 g/cm 3 [36,39].…”

“…The application of the HDPE composites is a function of the favorable properties coupled with cost implication of the production, and it may be affected by additional modified agents such as fiber or filler, NaOH, acetic anhydride, zeolite, and sodium lauryl sulfate. The use of recycled HDPE composites has been reported for many applications such as packaging (food storage containers and bottles for milk jugs) [13,28,38], banners, swimming pool installation, corrosion protection for steel pipelines, folding chairs and tables, electrical and plumbing boxes, plastic surgery (skeletal and facial reconstruction) [27], modified asphalt for pavement and road construction [29,59,75], housewares, industrial wrapping and gas pipes [30], and storage sheds, enhancing the economic, health, and social values as well as minimizing environmental issues that might be posed by HDPE disposal [38]. Applications of recycled HDPE in the encapsulation of radioactive, hazardous, and mixed wastes have been reported by Lageraaen and Kalb [76].…”

“…Incorporation of recycled LDPE at concentrations ranging from 2 to 5% by mass of bitumen possesses consistent desirable properties for bitumen asphalt applications [51,69]. Utilization of LDPE for production of liquid milk packaging [16], bread packaging and sandwich bags, housewares, toys, buckets, wire and cable jacketing, and carpet [13,38,68] and use of recycled thermoplastics for encapsulation of hazardous, radioactive, and mixed waste disposal save the environment from economic, environmental, and health issues [76].…”
