In the pharmaceutical industry, product protection is not just a requirement—it’s a responsibility. Medicines must be shielded from contamination, environmental stress, and physical damage throughout their journey from manufacturing to the patient’s hands. This is where functional coatings play a critical role. These advanced coatings enhance packaging performance, ensure product stability, and help pharmaceutical manufacturers meet stringent global safety standards.
Why Functional Coatings Matter in Pharma Packaging
Pharma products are highly sensitive to moisture, oxygen, temperature fluctuations, friction, and even chemical interactions. Without proper protection, these factors can compromise drug potency, safety, and shelf life. Functional coatings provide an added layer of assurance by reinforcing the packaging’s physical and chemical resistance.
These coatings are applied to packaging films, cartons, blister materials, and paper-based substrates. They serve multiple roles—barrier enhancement, sealing functionality, durability improvement, and contamination prevention—making them indispensable in modern pharmaceutical packaging.
Key Benefits of Functional Coatings
1. Moisture and Oxygen Protection
Medication stability is often threatened by humidity and oxygen exposure. Barrier coatings prevent moisture ingress and oxygen penetration, helping maintain product efficacy throughout its shelf life.
2. Grease, Oil, and Chemical Resistance
Many pharma processes involve oils, solvents, or aggressive chemicals. Coatings provide an essential protective shield that prevents staining, damage, and degradation of the packaging.
3. Enhanced Durability and Shelf Stability
From transportation to storage, pharmaceutical packaging must withstand significant mechanical and environmental stress. Coatings improve abrasion resistance, heat resistance, and structural robustness.
DIC’s Coating Technologies Supporting Pharmaceutical Safety
Here are two advanced functional coating solutions from DIC’s portfolio that directly support the pharma industry:
SunSys™
SunSys™ is a comprehensive range of coatings engineered to enhance packaging resistance against moisture, oil, grease, heat, friction, and industrial chemicals—factors commonly encountered in pharmaceutical production and logistics.
Key features of SunSys™ include:
- Prevents penetration of industrial grease and oils
