PACKING MATERIALS IN PHARMA

📦 Packing Materials in Pharmaceuticals

1. SOP for Sampling of Packing Material
2. Standard Testing Procedure for Packing Material
3. Standard Testing Specification for Packing Material
4. Certificate of Analysis for Packing Material

🎯 Purpose

Packing materials protect drug products from:

• Contamination
• Physical damage
• Moisture, light, oxygen
• Counterfeiting
• Loss of potency

They also:

• Provide identification & information
• Ensure controlled dosing

🧭 Classification of Packing Materials

1️⃣ Primary Packing Materials
These directly come into contact with the drug.
Examples:

• Blister packs (PVC/Alu)
• Glass vials & ampoules
• Plastic bottles
• Sachets & pouches
• Pre-filled syringes

2️⃣ Secondary Packing Materials
These do not touch the product directly; they protect and group primary packs.
Examples:

• Cartons
• Labels
• Leaflets/inserts
• Outer boxes

3️⃣ Tertiary Packing Materials
Used for bulk handling and transport.
Examples:

• Corrugated shipping boxes
• Pallets
• Stretch/shrink films

🚩 Special Considerations

• Child-resistant packaging for safety
• Tamper-evident features
• Anti-counterfeit measures: holograms, barcodes, serialization
• Compatibility studies with the drug (stability testing)
