Food packaging is used worldwide and is a common technique for protecting food safety and quality while increasing shelf life. Environmental issues caused by using polymers in packaging derived from petroleum are becoming more significant and more well‐known. Interest in ecofriendly packaging materials made of renewable resources (biopolymers) has steadily increased, particularly for temporary and throw‐away packaging applications. However, biopolymers frequently have poor processability, poor mechanical, and poor barrier characteristics, restricting their industrial application and scalable manufacturing. Researchers have created bionanocomposites with improved packaging qualities like antibacterial function, mechanical toughness, optical clarity, and gas and water barrier properties to overcome these restrictions. This review seeks to inform readers about recent advances in active food packaging that use biopolymers and bionanocomposite materials. The difficulties and possibilities presented by such resources for the food packaging sector have been examined. This review is timely given the recent spike in interest in research projects both in academia and industry seeking to create a new group of materials for packaging based on biopolymer for food with potential uses elsewhere.

Due to the increasing need to transport fluids, the use of industrial pipes and their sustainability is a crucial aspect to address. The motive of this work is to predict the behaviour of a pre-cracked pipeline under internal and external pressure using Finite element simulation. An intermediate range of pressure conditions has been selected to analyse the dispersal of normalized stress intensity factor along a semi elliptical crack front for a predefined crack geometry. This work also presents a comparative study of various piping material behaviour to address a relatively better choice for industrial use. Among the various alloys considered in the analysis Inconel 625 was found to be most appropriate for the pressure range.
