1. Introduction to Pharmaceutical Packaging

Pharmaceutical packaging is a critical component in the healthcare supply chain, ensuring the integrity, safety, and efficacy of medicinal products from production to patient use. This guide explores advanced packaging technologies, materials, machinery, and industry trends to help manufacturers, suppliers, and stakeholders make informed decisions.

2. Key Functions of Pharmaceutical Packaging

• Protection: Shields against physical damage, microbial contamination, UV light, moisture, and oxygen.
• Preservation: Maintains chemical and physical stability during storage and transport.
• Identification: Displays essential information (drug name, dosage, batch number, expiry date).
• Patient Safety: Features tamper-evidence, child-resistant closures, and compliance aids.
• Regulatory Compliance: Adheres to GMP, FDA, EMA, and serialization requirements.

3. Categories of Pharmaceutical Packaging

1) Primary Packaging

Direct contact with the product.

• Examples:
• Blister Packs: PVC/Alu or Alu/Alu films for tablets/capsules.
• Bottles: HDPE/PET (lightweight) or amber glass (UV protection).
• Vials/Ampoules: Type I borosilicate glass for injectables.
• Sachets: Multi-layer laminates (PET/AL/PE) for powders.

Technical Parameters:

• Blister Packs: Water vapor transmission rate (WVTR) <0.01 g/m²/day.
• Vials: USP <660> compliant; hydrolytic resistance Class I.

2) Secondary Packaging

Protects and groups primary packages.

• Examples:
• Cartons with QR codes for traceability.
• Tamper-evident shrink wraps.

3) Tertiary Packaging

Bulk handling and logistics.

• Examples:
• Corrugated boxes with humidity indicators.
• Insulated containers for cold chain (2–8°C).
