Flexible Packaging For Pharmaceutical

Pharmaceutical flexible packaging is a specialized, tailored solution designed to match the unique needs of various drugs. It focuses on providing optimal barrier protection based on the drug’s sensitivity, helping maintain stability, extend shelf life, and preserve therapeutic effectiveness—all while ensuring high-quality printing and mechanical durability.

Tailored Barrier Protection for Drug Sensitivities

Different medications require specific safeguards to prevent degradation:

• Oxygen-Sensitive Biologics: Incorporates high oxygen barrier layers like EVOH or PA to block oxygen ingress.
• Moisture-Sensitive Tablets: Uses ultra-high water vapor barrier structures, often with aluminum foil, to keep out humidity.
• Photosensitive Medications: Includes light-blocking materials to shield against UV and visible light exposure.

These features, common in the soft packaging industry, help prevent contamination and ensure the drug remains potent throughout its lifecycle.

Multi-Layer Structure: Combining Material Strengths

The packaging’s scientific design integrates multiple layers for comprehensive performance:

• Outer Layer (e.g., PET or BOPP): Offers excellent printability for clear branding, along with scratch resistance and overall mechanical protection.
• Middle Layer (e.g., Aluminum Foil, VMPET, or BOPA): Provides targeted high-barrier properties against gases, moisture, and light.
• Inner Layer (e.g., PE or CPP): Ensures strong heat-sealability, compatibility with drug contents, and meets pharmaceutical-grade safety standards.

This layered approach, a staple in flexible packaging, balances functionality with cost-efficiency and regulatory compliance.

Flexible Customization Options

Materials and production processes can be adapted to fit the exact properties of the pharmaceutical product, such as its formulation, storage requirements, or handling conditions. This customization minimizes risks like oxidation or moisture damage while optimizing for production scalability.

Typical Material Configurations

Common multi-layer setups include:

• PET/AL/PE: Ideal for high-barrier needs with aluminum for moisture and light protection.
• BOPA/AL/PE: Enhances strength and puncture resistance for robust applications.
• PET/VMPET/PE or CPP: Cost-effective for general pharma use with vacuum metallized layers for added barriers.
