        The need for food packaging to maintain quality and shelf life is increasing day by day. Nanostructured materials are preferred over microstructures due to their unique physical and chemical properties and improved performance. Advanced packaging based on nanotechnology has made it possible to preserve and transport food safely without changing the taste and quality. In addition, it prevents contamination and preserves the mechanical, physiological, physical and chemical properties of food. Various nanomaterials have been used in food packaging to prepare improved, active, smart and bio-based packaging. Smart packaging ensures food safety by detecting contamination, gases, humidity, temperature and other food parameters using sensors. With the increasing demand for the production of new, environmentally friendly and high-performance packaging, "bio-nanocomposites" have attracted a lot of attention in recent years. Bio-nanocomposites are bio-based polymers that consist of two main components, one acting as a matrix called biopolymer (continuous phase) and the second as a reinforcing agent (dispersed phase) with dimensions ranging from 1 to 100 nm. . Bio-based packaging is a new and new generation packaging that replaces natural polymers with synthetic plastics. In this article, recent research in the field of bio-nanocomposites has been reviewed based on the application for different needs and the possible risk of nanoparticle migration. Manuscript profile

        Advances in the synthesis and industrial production of carbon nanomaterials, particularly carbon nanotubes (CNTs) have been widely used in the polymer materials industry in the past few decades, leading to the creation of a group of carbon nanotube-reinforced polymer composites that exhibit the potential to be used in several applications, such as military, transportation, aerospace, automotive, and sports equipment. The advantageous thermal, electrical, and mechanical properties of CNTs, in conjunction with their low density, which encourages researchers to use them in making polymer composites. Polymeric composites have been welcomed by many researchers and industrialists due to their special properties including low weight, favorable mechanical properties and diverse production processes compared to other types of composites and other engineering materials. On the other hand, CNTs are unique as mechanical reinforcement components for structural applications due to their nanometer dimensions and extraordinary strength. Therefore, in this review study, an attempt has been made to examine the researches carried out in the field of mechanical properties of polymer composites reinforced with CNT. The implications of several factors affecting mechanical properties of CNT reinforced polymer composites such as amount, shape, and contact area of the reinforcing agents with the polymer matrix, have been highlighted.
