TL;DR: In this article, the preparation of the film based on aloe vera gel and polyvinyl alcohol (PVA) were carried out in this work, the film has high adhesion due to the presence of polyvinYL alcohol.
Abstract: The preparation of the film based on aloe vera gel and polyvinyl alcohol (PVA) were carried out in this work. The film has high adhesion due to the presence of polyvinyl alcohol. The mechanical properties like tensile strength and the transparency of the film were tested. The temperature withstanding ability of the film is tested with Thermo gravimetric analysis. The functional groups of the film were identified. The films prepared were evaluated by incorporation of an antifungal and an antibacterial agent which shows marked inhibition on growth of mold, yeast and bacteria. The Shelf life of the vegetables was tested using the film.

TL;DR: In this article, the authors discuss the current status and sustainability of these two next generation biobased plastics by taking into consideration the raw materials required, as well as the post-consumption effects of these materials on the environment.
Abstract: Advances in science and technology have resulted in the rapid development of modern society, which is clearly unsustainable because of the strain it places on current resources. The energy and materials needed to sustain the present society are derived primarily from non-renewable fossil resources, which will be depleted at some point. Plastics are one example of an important commodity in the modern lifestyle. While plastics are undoubtedly superior materials in terms of their costs, processability and functional properties, they are currently derived from fossil resources and they are not readily assimilated by the various ecosystems upon disposal. The search for biodegradable plastics that are derived from renewable resources has been ongoing since the 1970s. Two of the most promising biobased plastics, i. e., polylactic acid and polyhydroxyalkanoates, have received much attention as potential alternatives to existing processes. This article will discuss the current status and sustainability of these two next generation biobased plastics by taking into consideration the raw materials required, as well as the post-consumption effects of these materials on the environment. In addition, important issues surrounding the development and sustainability of biobased and biodegradable plastics will be highlighted.

TL;DR: In this article, Na-alginate- and κ-carrageenan-based antimicrobial films were prepared, to examine their antimicrobial effect and mechanical properties.
Abstract: Na-alginate- and κ-carrageenan-based antimicrobial films were prepared, to examine their antimicrobial effect and mechanical properties. Antimicrobial agents: lysozyme, nisin, grape fruit seed extract (GFSE) and ethylenediaminetetraacetic acid (EDTA) were incorporated into films, both alone and in combination. Na-alginate-based films exhibited larger inhibitory zones compared to κ-carrageenan-based films even within similar combinations and levels of antimicrobial agents. GFSE-EDTA in both Na-alginate- and κ-carrageenan-based films showed inhibitory effect against all indicator microorganisms. Tensile strength (TS) values were weaker and elongations (E) before breakage less frequent for films with antimicrobial compounds compared to that of films without the antimicrobial compounds.
