π¦ Packing Materials in Pharmaceuticals
- SOP for Sampling of Packing Material
- Standard Testing Procedure for Packing Material
- Standard Testing Specification for Packing Material
- Certificate of Analysis for Packing Material
π― 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
π§ Classification of Packing Materials
1οΈβ£ 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
2οΈβ£ Secondary Packing Materials
These do not touch the product directly; they protect and group primary packs.
Examples:
- Cartons
- Labels
- Leaflets/inserts
- Outer boxes
3οΈβ£ Tertiary Packing Materials
Used for bulk handling and transport.
Examples:
- Corrugated shipping boxes
- Pallets
- Stretch/shrink films
π§ͺ Common Materials Used
| Material Type | Examples & Use |
|---|---|
| Glass | Type I (borosilicate), Type II, Type III for vials, ampoules |
| Plastic | HDPE bottles, LDPE droppers, polypropylene closures |
| Metals | Aluminum tubes, caps, blister foils |
| Paper & Board | Cartons, inserts, labels |
| Films & Laminates | PVC, PVDC, PET for blisters, sachets |
π Regulatory Requirements
Packing materials must:
β
Be pharmaceutically acceptable (non-reactive, non-toxic)
β
Meet USP/EP standards (e.g., tests for extractables & leachables)
β
Be traceable (lot numbers)
β
Be stored under controlled conditions
β
Be approved through vendor qualification & QA release
Regulatory bodies involved:
- FDA (21 CFR Part 211)
- EU GMP Annex 9 (Packaging)
- WHO GMP
- ICH guidelines
π Examples of Packing Configurations
- Tablets: Blister strip + carton + shipper box
- Injectables: Glass vial + flip-off seal + carton + leaflet
- Syrups: PET bottle + cap + label + carton
π© Special Considerations
- Child-resistant packaging for safety
- Tamper-evident features
- Anti-counterfeit measures: holograms, barcodes, serialization
- Compatibility studies with the drug (stability testing)
