Green Procedure

Currently, the production and application of non-biodegradable petroleum-based synthetic polymer (commonly known as plastic) are highly prevalent. As synthetic polymers as mostly non-biodegradable, they adversely affect the environment and result in the generation of excessive solid waste. The increasing awareness about the ill-effects of synthetic polymers among consumers has resulted in a demand for natural, disposable, biodegradable, reusable, or recyclable food packaging materials. Bio-based polymers and biopolymers have been one of the most favorable alternatives to be exploited and developed into eco-friendly food packaging materials. Certain microorganisms, such as Gluconoacetobacter xylinus, produce cellulose by a fully green procedure which is called bacterial cellulose. Bacterial cellulose demonstrates exceptional properties such as being a chemically pure material, highly flexible, high water absorbency, great tensile strength, highly crystalline nature, highly moldable, non-toxic nature, and biocompatible. However, there are some limitations such as lack of antibacterial properties, optical transparency, and stress-bearing capability which can be overcome by developing bacterial cellulose composites using hydrocolloids like proteins, starches, pectins, etc. The bacterial cellulose composites are employed to develop packaging films with properties such as high mechanical strength; antimicrobial, transparent, biodegradable, with air, water, and oil resistance properties, thus, making it an appropriate material for packaging.

Negative Impacts

The commonly used food packaging materials are made from synthetic polymers derived from petroleum. However, the use of synthetic polymers has negative impacts on the environment, because it is difficult to degrade naturally either by the biotic or abiotic process. Although their complete replacement with eco-friendly packaging films is just impossible to achieve economically, at least for a specific application like food packaging the use of bioplastics should be the future. One of the alternatives is to blend synthetic polymer for instance polypropylene (PP) with a natural polymer like poly-lactic acid (PLA). Because their mixture is an immiscible blend because they have highly different polarity, it is necessary to add a compatibilizer such as polypropylene-grafted maleic anhydride (PP-g-MAH) in order to increase the properties of its blend miscibility. The objective of this research was to study the influence of PLA addition to the thermal properties of their blend product with PP. The combinations of PP with PLA in the ratios of (80:20); (90:10); (95:5) were prepared and then characterized for their thermal property behaviour by means of TG and DSC. The results showed that increasing the amount of PLA will decrease their enthalpy significantly

Starch Films

The application of starch films, such as food packaging materials, has been restricted due to poor mechanical and barrier properties. However, the addition of a reinforcing agent, cellulose nanofibers (CNF) and also thymol, into the films, may improve the properties of films. This work investigates the effects of incorporating different concentrations of thymol (3, 5, 7, and 10 wt.%) on physical, mechanical, water vapor barrier, and antibacterial properties of corn starch films, containing 1.5 wt.% CNF produced using the solvent casting method. The addition of thymol does not significantly affect the color and opacity of the films. It is found that the tensile strength and Young’s modulus of the films decreases from 10.6 to 6.3 MPa and from 436.9 to 209.8 MPa, respectively, and the elongation at break increased from 110.6% to 123.5% with the incorporation of 10 wt.% thymol into the films. Furthermore, the addition of thymol at higher concentrations (7 and 10 wt.%) improved the water vapor barrier of the films by approximately 60.0%, from 4.98 × 10—9 to 2.01 × 10—9 g/d.m.Pa. Starch/CNF/thymol bionanocomposite films are also found to exhibit antibacterial activity against Escherichia coli. In conclusion, the produced starch/CNF/thymol bionanocomposite films have the potential to be used as antibacterial food packaging materials.

Overconsumption of plastic goods and improper handling of petroleum-derived plastic waste have brought a plethora of negative impacts to the environment, ecosystem and human health due to its recalcitrance to degradation. These drawbacks become the main driving force behind finding biopolymers with the degradable properties. With the advancement in biopolymer research, polyhydroxyalkanoate (PHA) and poly(lacyic acid) (PLA) and its composites have been alluded to as a potential alternative to replace the petrochemical counterpart. This review highlights the current synthesis process and application of PHAs and PLA and its composites for food packaging materials and coatings. These biopolymers can be further ameliorated to enhance their applicability and are discussed by including the current commercially available packaging products. Factors influencing biodegradation are outlined in the latter part of this review. The main aim of this review article is to organize the scattered available information on various aspects of PHAs and PLA, and its composites for packaging application purposes. It is evident from a literature survey of about 140 recently published papers from the past 15 years that PLA and PHA show excellent physical properties as potential food packaging materials.

Abstract Background: Phthalate esters (PAEs) are a group of chemical compounds widely used as plasticizers to increase the flexibility of plastics that are used in the manufacturing of kitchen utensils and food containers. Objective: In this study, a simple, rapid, and sensitive method for the determination of 20 PAEs in different kinds of food packaging materials has been developed. Methods: Samples injected with five internal standards were extracted with acetonitrile saturated with n-hexane and then detected by GC-MS/MS without a purification step. Results: The standard calibration curves were linear for all analytes over the concentration range of 5–500 μg/L, and the correlation coefficients ranged from 0.9913 to 0.9999. The LODs and LOQs were in the ranges of 1.7–62.5 and 5.5–208.3 μg/kg, respectively. The accuracy of this method was evaluated by measuring the recovery from spiked samples. The recoveries of all 20 phthalates from samples spiked at three different concentrations were measured, and the recovery was in the range of 82.1–110.8% and the relative standard deviation range of recovery result (n = 6) was 0.3–9.7%. Conclusions: The method presented here is simple, rapid, and sensitive and can be applied to large-scale detection of PAEs in plastic materials. Highlights: Instead of only one solvent, acetonitrile saturated with n-hexane was used as the extraction solvent. Samples were pretreated without a purification step. Five internal standards were used for quantitative determination.
