The Milk Powder Air Column Bag represents a medical-grade protective packaging solution engineered to shield powdered products—especially milk powder—from moisture, oxidation, compression, and impact during storage and transit.
Key Points:
Milk Powder Air Column Bag — Premium Protective Packaging
The Milk Powder Air Column Bag is engineered from LLDPE and nylon co-extruded film, a medical-grade substrate designed for the highest standards of hygiene and durability. Its unique structure of independent air columns ensures each chamber maintains inflation for up to 12 months under normal conditions, providing consistent cushioning and structural integrity throughout storage and transport.
This advanced design effectively prevents clumping, contamination, or spoilage, safeguarding the quality and freshness of powdered products. The bag’s airtight and stable air columns create a protective barrier that minimizes movement and absorbs shocks, making it ideal for food, pharmaceutical, and nutritional products where safety, hygiene, and long shelf life are critical.Perfect for manufacturers, distributors, and logistics providers, the Milk Powder Air Column Bag ensures powdered products reach consumers in pristine condition, combining premium protection with efficiency and convenience.
Features
Multi-Layer Protection：Crafted from coextruded LLDPE and nylon film, the bag combines flexibility and tear resistance with superior puncture strength. This dual-layer structure forms a reliable barrier against moisture, dust, and oxygen, keeping powdered products fresh and safe.
Air-Locking Technology：Each air column features a one-way check valve that automatically seals after inflation. Even if one column is punctured, the remaining columns stay fully inflated, ensuring uninterrupted protection.
Food-Safe & Non-Toxic：Made from BPA-free, food-grade materials, the bag meets strict global food contact standards, guaranteeing no chemical contamination or leaching into milk powder or other nutritional products.
Space-Saving & Efficient：Ships flat, reducing transportation volume by up to 80% compared to pre-inflated packaging, and inflates on-demand with standard inflation equipment. Optimizes warehouse storage and reduces shipping costs.
Hot-Sealed Edge Design：Precision sealing ensures that damage to a single column does not compromise the performance of the remaining columns, maintaining overall integrity.
Unidirectional Air Valve：Advanced one-way valves allow smooth, unobstructed airflow during inflation and lock air for long-lasting cushioning, maximizing protection throughout storage and transport.
Eco-Friendly & Durable：Produced from recyclable, strong, and flexible materials, the bag enhances product safety while supporting sustainable packaging initiatives.
Using Tutorial
Locate the Air Port – Find the air inlet marked with an arrow.
Inflate – Use a pump to fill the bag to about 85%, ensuring soft yet firm cushioning.
Load Product – Place milk powder or powdered goods inside; the air columns fully wrap the product.
Seal & Store – Close the air port. The bag now provides 360° protection, keeping your product safe from shocks, compression, and moisture
FAQs
Q: Can the bags be reused?
A: While not recommended for reuse (to avoid contamination risks), they are 100% recyclable through standard plastic recycling streams, supporting circular economy practices.
Q: How to inflate the bags efficiently?
A: Use a C20 Inflation Machine with 50–70% airflow (0.3–0.5MPa pressure) to achieve optimal inflation without overstretching the film, ensuring maximum protection.
Q: Do the air columns fail independently if punctured?
A: Yes, each column operates independently—only the damaged column deflates, while remaining columns maintain 90% of the original protective capacity, minimizing product risk.
Q: What storage conditions are recommended for unused bags?
A: Store in a cool (15–25°C), dry (relative humidity <60%) environment away from direct sunlight to preserve film integrity and valve functionality.
