In the production of oral dissolving films (ODF), casting and drying materials form the foundation that determines film uniformity, stability, taste, and overall product performance. At RSBM, we integrate material science with advanced equipment engineering to deliver highly consistent, pharmaceutical-grade film substrates tailored to your formulation and application needs.

1. High-Purity Polymer Bases for Optimal Film Structure

We select and validate premium-grade film-forming polymers—including HPMC, pullulan, PVA, sodium alginate, and specialized blends—to achieve the ideal balance of tensile strength, flexibility, dissolution rate, and mouthfeel.
Each polymer is tested for viscosity, particle size, compatibility with active ingredients, and drying behavior.

2. Precision Casting Solutions

Using RSBM-engineered casting modules, liquids are spread into ultra-uniform layers with micrometer-level precision.
Stable rheology, controlled flow properties, and anti-bubble treatments ensure consistent film thickness from start to finish.

3. Controlled Drying for Consistency and Stability

The drying phase is critical—temperature, airflow, pressure, and humidity must be perfectly synchronized.
RSBM’s drying systems avoid hotspots, prevent cracking or brittleness, and preserve thermo-sensitive active ingredients like vitamins, enzymes, probiotics, and herbal extracts.
Moisture-control materials and barrier components are used to ensure shelf-life and stability.

4. Customizable Material Systems

Based on your product’s requirements—fast melt, taste masking, high-load actives, caffeine/nicotine formats, pet films, beauty/functional ODFs—we design customized casting and drying material systems, including:

  • Rapid-dissolution base materials

  • Heavy-loading polymer matrices for strong doses

  • Cooling-sensitive formulations

  • Transparent or opaque film bases

  • Natural/vegan ingredient systems

  • Sugar-free and clean-label options

5. Full-Chain Integration With RSBM Equipment

All casting & drying materials are validated on our ODF production lines to guarantee compatibility and manufacturing efficiency.
Clients can use our formulas, or RSBM can adjust materials to fit your existing equipment and regulatory requirements.
