Why Biopolymer Packaging Materials are Better

Abstract

The upcoming packaging material trend is bio-polymeric materials since it has shown tremendous potential in practical scenarios. Even though there have been experiments performed regarding material developments, there is still no confirmation about how uncertain the developments will be. A few statistical approaches were carried out in this work to identify the role of biopolymers as a packaging material based on their thermo-mechanical and physical properties and potential compared to other packaging materials. To determine the potential of biopolymer, it is compared with other package materials currently in demand. There are three main steps in the research. The first stage is an analysis of selected different packaging materials based on Multi-criteria decision making (MCDM) technique. The material properties are analysed through the criteria of TOPSIS analysis. The ideal and negative ideal alternatives have been identified. Biopolymers have an outcome as the final best alternative among others. To confirm the TOPSIS results and its uncertainties, a sensitivity analysis is performed. This sensitivity analysis was performed in two phases. The first step is a regression analysis of the weighted parameters and input variables of the TOPSIS scheme. The second step is the variation of weights in a unitary variation ratio to identify the order of the TOPSIS results at each variation. Finally, all the results have concluded that the research intention has been fulfilled by performing TOPSIS and the sensitivity analysis has also confirmed this decision.

Technology for the Production of Environment Friendly Tableware

“…Biodegradability means that the material is capable of undergoing aerobic and anaerobic degradation which results in the formation of CO2, H2O, methane, biomass and mineral salts. Biodegradable material may not be compostable [9]- [12]. The composting process consists of the decomposing of organic waste by the microbes, i.e., the production of compost.…”

Development of Bio-Based and Biodegradable Plastics

“…In the food industry, it is of great importance to recognize the characteristics of both the applicable food product and the type of bio-based and biodegradable polymer to be used for packaging or coating [8]. This is because deterioration of food products, as well as degradation of some biodegradable and bio-based polymers, is influenced by similar factors such as environmental temperature, relative humidity, ultraviolet exposure, and the activity of bacteria and spoilage microorganisms [96].…”

Biopolymers for Nano-Enabled Packaging of Foods

“…Films based on cellulose derivatives have efficient properties like flexible, tough, transparent, odorless, high resistance to fats and oils. But they have poor water resistance (Silva and Blumberga 2019). Chitosan that is derived from chitin has good resistance to oxygen, fat, and oil (Nesic et al 2020).…”

“…Recently, industries are focusing towards lighter weight materials for packaging of food materials in order to reduce the quantity of packaging material used, transportation costs, and the amount of waste disposal (Silva and Blumberga 2019). Increased environmental concerns have led to the usage of biopolymers in packaging which reduces waste disposal (Naiaretti and Tita 2012).…”
