Special Issue Information

Dear Colleagues,

Natural resources play a pivotal role in the quest for sustainable packaging-based solutions. In utilizing sustainable packaging, we aim to minimize environmental impact throughout the lifecycle of such packaging, from production to disposal. Utilizing natural resources in packaging materials can significantly contribute to achieving this goal.

Wood-based materials, such as paper and cardboard, are among the most commonly used natural resources in packaging. These materials are renewable and biodegradable; they have a relatively minimal environmental footprint compared to traditional plastic packaging. Moreover, advancements in wood-based packaging technology, such as innovative pulping and processing methods, have enhanced their strength and durability, thereby making them suitable for a wide range of products.

Another prominent natural resource for sustainable packaging is plant-based polymers, such as bioplastics. Derived from renewable sources like corn starch, sugarcane, or cellulose, bioplastics offer a renewable alternative to conventional petroleum-based plastics. Bioplastics can be biodegradable, compostable, or recyclable, depending on their composition, making them environmentally friendly options for various packaging applications.

Furthermore, natural fibres from agricultural by-products, such as wheat straw, rice husks, or hemp, are increasingly utilized in sustainable packaging. These fibres can be processed into sturdy packaging materials that are biodegradable and compostable. By diverting agricultural waste from landfills and utilizing it for packaging, these materials contribute to reductions in waste and promote the principles of the circular economy.

Additionally, bio-based coatings and adhesives derived from natural sources, such as plant oils or resins, are utilized to enhance the performance and sustainability of packaging materials. These coatings provide barrier properties, moisture resistance, and adhesion while being biodegradable and non-toxic.

Harnessing natural resources for sustainable packaging will produce promising solutions for the mitigation of environmental concerns associated with traditional packaging materials. By embracing renewable materials, biodegradable options, and bio-based technologies, the packaging industry can minimize its ecological footprint and move towards a more sustainable future.

The concept of food packaging plays a crucial role in ensuring consumer satisfaction and extending the shelf life of food products. The rising trend of introducing innovative materials for food packaging has become prominent in recent years. The present study aims to investigate the impact of rosehip seed oil (RSO) on the physical, physicochemical, antioxidant, and antimicrobial properties of edible films based on chitosan for potential fruit packaging applications. Scanning electron microscopy revealed a uniform distribution of the incorporated emulsion throughout the edible film. The addition of RSO increased the deformation at break in both tensile and puncture test, thereby improving the elastic properties of the films. The resulting films exhibited a light-yellow color with high opacity. The immobilization of RSO led to a decrease in water content by almost two times and an increase in water vapor permeability of the films. The films showed enhanced antioxidant activity and retained good protective properties against the yeast S. cerevisiae. Consequently, these newly formulated multicomponent films are found to be suitable for applications in the development of active food packaging because of their physical, antioxidant, and antimicrobial properties.
