Silkworm fibre has been identified as a suitable material for biomedical and electronics applications because of its superior optical, mechanical and biological properties. Herein, we present comparative studies pertaining to the structural and morphological features of naturally harvested moth caterpillar silk fibre samples obtained from domesticated (Bombyx mori) as well as wild species, viz. Antheraea mylitta and Antheraea papiha. It has been observed that silk fibres obtained from silk cocoons are several microns in thickness. Surprisingly, wild variety, i.e. tasar silk samples show better structural and morphological properties. These fibres may find broad-spectrum applications in biomedical and electronics research.

The demand for innovative solutions has arisen from the inevitability of improved packaging systems to protect processed food from various factors that cause spoilage. Traditional food packaging materials have limitations in fulfilling all the requirements of consumers, such as being inert, cheap, lightweight, easily degradable, reusable, and resistant to physical abuse. Nanofillers incorporated in the polymer matrix can provide potential solutions to these challenges. This review paper deliberates the use of nanofillers in a polymer matrix to develop an active and intelligent polymer nanocomposites-based processed food packaging system. The present review article focuses on the properties of nanofillers and their potential benefits when incorporated into the polymer matrix. It also examines the challenges associated with developing such packaging systems and explores the ways to address them. It highlights the potential of nanofiller-based polymer nanocomposites in developing a novel food packaging system that can improve the shelf-life and quality of processed food. Such systems can protect food from dirt or dust, oxygen, light, moisture, and food-spoiling microorganisms. Incorporating nanofillers can provide a viable solution to these problems. Most importantly, this paper provides research insights into the potential benefits of nanofillers-based polymer nanocomposites and their applications in the food packaging industry. The verdicts of this review will be of interest to the food packaging industry, entrepreneurs and researchers interested in developing sustainable and innovative packaging systems.
