Film coating is a sophisticated process in pharmaceutical manufacturing, essential for enhancing the performance and appeal of solid dosage forms. At NINGBO INNO PHARMCHEM CO.,LTD., we delve into the science behind our high-quality tablet coating powders to ensure our partners understand the benefits they bring to drug formulations.

The core principle of film coating involves applying a thin polymer layer onto the tablet surface. This layer serves multiple critical functions. Firstly, it acts as a protective barrier, shielding the active pharmaceutical ingredient (API) from external elements. This is particularly vital for drugs sensitive to moisture or light, thereby improving overall product stability. Our materials are designed to provide excellent protection, addressing concerns such as hygroscopicity, which can affect the integrity of tablets, especially those derived from traditional Chinese medicine.

Secondly, film coatings significantly influence the tablet appearance. A uniform, well-adhering film provides a smooth surface, consistent color, and can be imprinted with product identification marks. This aesthetic enhancement is crucial for branding and patient recognition. Our premixes are formulated to create visually attractive tablets with a professional finish.

The application process itself requires careful control of parameters like spray rate, drying air temperature, and pan rotation speed. The rheological properties of the coating dispersion, determined by the choice of film formers and other excipients, are key to achieving uniform coverage and preventing defects like bridging or orange peel. As a supplier of a vital tablet film coating raw material, NINGBO INNO PHARMCHEM CO.,LTD. ensures our powders contribute to optimal dispersion and film formation.

Furthermore, specialized film coatings can be designed for targeted drug release. While our primary offering focuses on general film coating, the underlying science allows for future developments in areas like enteric coating or sustained-release formulations. These advanced coatings ensure that the API is released at the optimal site and rate within the body, maximizing therapeutic effect and minimizing side effects.

As a manufacturer of medicine grade coating powder, NINGBO INNO PHARMCHEM CO.,LTD. adheres to the highest quality standards, ensuring our products are compliant with USP, BP, EP, and CP. This commitment to quality underpins the reliability and efficacy of the final coated tablet. By understanding the scientific principles of film coating, pharmaceutical manufacturers can leverage our excipients to produce superior drug products that meet both regulatory and patient expectations.
