The effectiveness of pharmaceutical film coating powders relies on a precise combination of carefully selected ingredients. These components work synergistically to form a protective, functional, and aesthetically pleasing film on tablets, capsules, and granules. At NINGBO INNO PHARMCHEM CO.,LTD., we leverage advanced polymer science and formulation expertise to develop high-performance film coating powders that meet the stringent demands of the pharmaceutical industry.

At the heart of any film coating powder is the film-forming polymer. These polymers provide the structural integrity and functional properties of the coating. Common film formers include Hydroxypropyl Methylcellulose (HPMC), which is widely used due to its versatility, good film-forming properties, and solubility in water and organic solvents. Other important polymers include Ethyl Cellulose (EC), which is insoluble in water and often used for moisture barrier properties or in combination with water-soluble polymers; Hydroxypropyl Cellulose (HPC), which has unique temperature-dependent solubility; and various acrylate copolymers, often used for specific release profiles like enteric or sustained release. NINGBO INNO PHARMCHEM CO.,LTD. utilizes a range of these high-quality polymers to offer diverse functionalities.

Plasticizers are another essential component. Polymers, when dried into a film, can be brittle. Plasticizers are added to increase the flexibility and extensibility of the film, preventing cracking and improving adhesion to the tablet core. Common plasticizers include polyethylene glycol (PEG), propylene glycol (PG), castor oil, and triacetin. The choice and concentration of plasticizer are critical for achieving the desired film properties, such as elasticity and resistance to mechanical stress. Our formulations are optimized to ensure the correct balance of polymer and plasticizer for superior film quality.

Colorants and opacifiers are often incorporated to provide the tablet with a specific color, enhance its visual appeal, and mask the color of the tablet core. Titanium dioxide (TiO2) has traditionally been a popular opacifier and white pigment, providing excellent hiding power. However, due to evolving regulatory landscapes and consumer preferences, we also offer TiO2-free formulations that achieve comparable aesthetics using alternative pigments. These can include iron oxides, calcium carbonate, and other approved colorants, ensuring compliance with 'clean label' initiatives where applicable.

Other additives may include anti-foaming agents to prevent foam formation during the coating process, and surfactants to improve wettability and dispersion. For specialized applications, ingredients that facilitate specific release mechanisms, such as pH-sensitive polymers for enteric coating or polymers that create a diffusion barrier for sustained release, are incorporated. The composition of our film coating powders, whether gastric soluble or enteric soluble, is meticulously designed to ensure ease of use, high coating efficiency, and superior performance.

When you buy film coating powder from NINGBO INNO PHARMCHEM CO.,LTD., you are acquiring a sophisticated blend of these key ingredients, expertly formulated and rigorously tested. Our commitment to providing high-purity, certified pharmaceutical intermediates ensures that your tablet formulations benefit from the latest advancements in coating technology, leading to enhanced product quality, patient satisfaction, and market success.
