Hormones are a group of biochemical messengers that assist in transmitting signals from one part of an organism to another. The term “hormone” was first coined by Ernest Starling in 1905 after the discovery of secretin, a chemical produced in the small intestine that regulates pancreatic secretions. In 1937 Went and Thimann defined hormones as “a substance which, produced in any one part of an organism, is transferred to another part and there influences a specific physiological process”. Since then hormones are also known as chemical messengers. These intercellular messengers are produced by specialized cells of endocrine glands, generally called effectors and released into the bloodstream thereby assisting in the regulation of physiological processes in target cells. Hormones assist in the regulation of a plethora of cell functions such as maintaining homeostasis, metabolism of biomolecules, growth, and reproductive function, and controlling blood pressure and glucose levels that are essential in orchestrating an intricate body- balance. The pituitary, thyroid, pancreas, adrenal, parathyroid, and gonads (testis and ovary in males and females respectively) produce hormones. Apart from these endocrine glands, few other organs such as the kidney, heart, and liver are also involved in hormone production. The pituitary gland

The demand is growing for packaging options that are recyclable, biodegradable, or reusable. Consumers also expect transparency, with clean labels and QR codes providing details on ingredients and sourcing, which has become essential for building trust (Santeramo et al.,2022) • Environmental Sustainability • Sustainability remains a powerful influence on packaging innovation. Reducing single-use plastics, increasing recyclable options, and adopting circular economy principles are all priorities. Both consumers and businesses are actively seeking solutions that reduce environmental impact, such as renewable, compostable materials and designs that minimize waste ( Fao et al ., 2022)

Global Packaging Regulations: FDA, EU, FSSAI, and Others FDA (U.S. Food and Drug Administration): The FDA ensures that food packaging materials are safe for contact with food in the United States. Under the Food, Drug, and Cosmetic Act (FDCA), the FDA provides guidelines through the Code of Federal Regulations (CFR), Title 21. Key points include: • Food Contact Substances (FCS): Materials in contact with food must be either pre-approved or recognized as safe (GRAS). Packaging materials, including plastics, paper, and adhesives, must undergo tests to ensure they do not release harmful substances into food. • Migration Limits: The FDA sets allowable limits on the migration of substances from packaging into food, including chemicals from inks, coatings, and polymers. • Food Packaging Certification: Packaging manufacturers must confirm that their materials meet FDA standards for safety in food contact

Technical and Economic Challenges in Advanced Packaging The implementation of advanced packaging technologies comes with a range of challenges. Technically, developing materials that are both highly effective and environmentally friendly is a complex task. Packaging must not only protect products and ensure their safety, but also minimize its ecological footprint. From an economic perspective, these advanced solutions tend to be more expensive, which can make it difficult for smaller businesses or those in cost-sensitive markets to adopt them on a large scale. Furthermore, the need for efficient production methods, scalable new materials, and affordable solutions continues to be a significant hurdle for the industry. Balancing Performance with Environmental Goals One of the primary challenges in packaging is achieving
