FAQs About Film coating
What is Film Coating for Tablets?
Film coating for tablets involves applying a thin layer of specialized tablet coating polymers onto the tablet’s surface. This process enhances tablet attributes such as film coating for sustained release, improved aesthetics, and protection against external factors.
Why do tablets need film coating?
Film coatings enhance mechanical integrity, provide barrier protection against moisture and oxidation, enable taste-masking, and support modified or delayed release profiles.
What types of coating systems are available?
We offer aqueous and non-aqueous film coatings, enteric coatings, glossy/pearlescent finishes, and titanium dioxide-free systems—each selected based on formulation and production requirements.
Can You Provide Examples of Film Coating Materials?
Film coating materials encompass a variety of polymers such as hydroxypropyl methylcellulose (HPMC), ethyl cellulose, and polyvinyl alcohol (PVA). These film coating material choices are meticulously made based on the required functionality.
What Are the Different Types of Film Coating?
Film coating can be broadly categorized into types of film coating tablet processes: aqueous film coating and non-aqueous coating. Each has unique advantages depending on the drug formulation.
How do I choose between aqueous and solvent-based coating systems?
Selection depends on formulation sensitivity, line equipment, solvent restrictions, and regulatory conditions. Our technical team can assist in matching the right system to your product.
Can film coating impact tablet dissolution or release profile?
Yes. Coating weight, polymer type, and layer architecture influence disintegration and release. Our systems are designed and tested to deliver precise performance with minimal impact on key dissolution parameters.
What Are Some Examples of Tablet Film Coating Applications?
Tablet film coating finds extensive applications in extended-release drugs, enteric film coated tablet designs, taste masking for patient compliance, and sustained release coating formulations.
