In the world of food and nutrition, we are always searching for more user-friendly and effective delivery methods. For the elderly with swallowing difficulties, infants who haven’t learned to chew, or busy modern individuals, a thin, paper-like film that dissolves instantly in the mouth may be the ideal solution.An oral dissolving film is like a "nutrient stamp that melts." Placed on the tongue, it quickly releases the active ingredients embedded within. It requires no water to swallow, eliminating the risk of choking and bypassing the liver’s first-pass effect, allowing nutrients to be absorbed by the body more directly.From natural materials like pullulan and chitosan to modern technologies such as electrospinning and 3D printing, researchers are continually exploring the possibilities of materials and the boundaries of techniques, enabling this small film to carry a vast future of health and convenience. This is not just an innovation in dosage forms but also a thoughtful design, making nutritional supplementation effortless and elegant from now on.
