“…[37,38,40] Both cellulose and starch are not plastic but can be transformed into plastics by polymer technology or fermentation [41] by using various techniques like casting [42] , mixing, extrusion [43] , injection molding, etc. [44] Bio-ethylene and Biopropylene have the prefix "bio", indicating that they are made from renewable materials, and have identical properties to that of petrochemical based plastics [45].

Petrochemical based plastics have been widely used as packaging materials, as they have good barrier properties, stiffness, tensile strength & tear strength. Although in great demand plastics have many disadvantages like very low water vapour transmission rate, non- biodegradability etc. which further causes environmental pollution. Keeping in mind about the pollution and harm caused to the nature, newer concepts about the use of bio-plastics came into force. Bio-plastics are produced from the biological sources such as potato, potato peels, corn, sugarcane, wheat, rice, banana peels etc. These plastics are environment friendly & biodegradable, and are safer option than the petroleum-based plastics. These biodegradable plastics break down into carbon dioxide, water & inorganic compounds and degrade completely. The time-line, sources and other important details about the bio-plastics have been presented in this review paper.

Bioplastics are kind of plastics produce from natural and renewable raw materials biomass sources such as sugarcane, corn starch, wood, waste paper, vegetable oils and fats, bacteria, algae, etc. Mostly, the commercial plastics in the marketplace are made from non-renewable petroleum based and this product can cause damaging to the ecosystem of the nature. Bioplastics are not harmful to nature environment because it can decompose back into carbon dioxide. Thus, the demand for applications of bioplastics are growing rapidly. The products made from bioplastics should be commercialize because they are renewable, biodegradable, compostable and environmentally friendly. The aims of this short review are to present about classifications of bioplastic, their advantages and disadvantages, processing, applications and challenges. Finally, the possible future developments of bioplastics are prospected.

“…The blends based on starch and polyvinyl alcohol (PVOH) present the advantage of being totally environmental destroyable materials and therefore were intensively studied [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. PVOH is a water soluble vinyl polymer which, at first sight, seems to be not biodegradable [9].…”

“…Biodegradation of PVOH in soil is expected to be very slow and to take place only under selective microorganisms actions [8]. The PVOH-starch materials are still attractive for applications which require particular properties such as film and/or thermoforming capability, chemical resistance, and transparency [8][9][10][11][12][13][14][15][16][17][18][19][20][21]. The greatest difficulty in achieving of these materials is mainly the consequence of high interactions between the macromolecules of each polymer, both of them having well-defined semicrystalline morphology: granular with concentric crystallineamorphous zones for starch and semicrystalline with high orthorhombic crystals for PVOH [9][10][11][12].…”

The paper proves that the miscibility of some blends based on starch can be improved by finding for each of them the melt resistance to flow at which the nonstationary flow and the melt degradation are avoided and the developed shear rate homogenizes optimally the material composition. The obtained results show that, for process sensitive materials like starches, the border between good and less miscibility is so narrow that the window of melt processing conditions and the best formulation must be found for each of them. The improving of miscibility by controlling the melt resistance to flow proves to be a good method to prevent retrogradation and plasticizer leaching and so to handle the new compounds behavior during usage.
