Why Is Packaging Critical for Milk Powder?
Milk powder is a high-value, moisture-sensitive dairy ingredient used across:
- Dairy and bakery formulations
- Infant food and nutrition
- Emergency and export-ready food systems
Because of its hygroscopic nature (tendency to absorb moisture), improper packaging can lead to:
- Stickiness and lump formation
- Nutritional degradation
- Flavor changes
- Reduced shelf life
Food manufacturing consultants advise using moisture and oxygen barrier materials to maintain quality across supply chains.
Characteristics of Milk Powder Affecting Packaging
- Moisture content: ~4–5%
- Requires low humidity environment
- Sensitive to oxygen, light, and humidity
- Risk of lumpiness and microbial growth if packaging fails
Types of Packaging for Milk Powder
Packaging varies based on use case, shelf life, and distribution scale:
Bulk Packaging
Used for large-scale storage and B2B transport.
Retail Packaging
Packaging Materials Used
- Aluminum Foil + Polyethylene Laminates
- Metallized Films for reflective protection
- Paper + Poly Film Structures (eco + functional)
- Bag-in-box with anti-static liners for automated lines
- HDPE / PET bottles for instant and flavored powders
Consultants guide on migration safety, compliance (FSSAI/Export), and material recyclability.
