Our moisture-resistant air column bags are specifically engineered for powdered milk packaging, made from high-barrier PA+PE composite material【(custom food-grade material options available for strict food contact requirements)】, with integrated leak-proof heat seals that effectively block external moisture, dust and microbial contamination, eliminating spills and oxidation risks during long-distance transport. The semi-transparent design allows for quick visual inspection of packaging integrity without opening the bag, while the independent air column structure provides 360° cushioning to absorb shocks, drops and extrusion during delivery. We support fully customizable sizes, patterns and brand printing options, and all materials are 100% recyclable, perfectly balancing product freshness protection, transportation safety and sustainable packaging goals for dairy brands.

The independent air column structure distributes impact force evenly across the entire packaging surface, reducing impact stress on milk powder cans by 80% compared to traditional bubble wrap. It effectively prevents can deformation, seal damage and powder leakage caused by drops, bumps and stacking pressure during transit, which is especially suitable for cross-border logistics with long transportation cycles and multiple handling links. 【Field test data shows that when dropped from a height of 1.5 meters, the damage rate of milk powder cans packaged with our air cushions is less than 0.2%, far lower than the 3.5% damage rate of traditional foam packaging.】
Its ultra-lightweight construction reduces overall shipping weight by 15% compared to foam inserts, directly lowering international transportation costs. When uninflated, it occupies 90% less storage space than pre-inflated packaging materials, which can save at least 60% of warehouse storage costs for enterprises with large packaging demands. 【The roll-type design is compatible with automated inflation equipment, and the packaging efficiency per unit of product is 3 times higher than that of manual foam wrapping, reducing labor costs for the packaging line.】
【Our exclusive multi-layer co-extrusion process creates a dense moisture barrier layer, with water vapor transmission rate 40% lower than ordinary air column bags. It can maintain the internal humidity of the package within 3% RH for up to 6 months in an environment with 90% ambient humidity, effectively preventing milk powder from caking, deteriorating and flavor loss caused by moisture ingress, and extending the effective shelf life of products in transit by 2 times.】
Thanks to the precision heat sealing technology with a sealing width of 15mm, the air columns retain air for more than 9 months without obvious leakage, ensuring continuous protection even during extended storage, slow shipping cycles or transcontinental transportation. 【Each batch of products undergoes a 72-hour air retention test before leaving the factory, so there is no need to worry about air leakage during transportation.】
Made from 100% recyclable materials, it supports global green packaging initiatives, reduces plastic waste by 70% compared to disposable foam packaging, and meets the packaging environmental protection regulations of the European Union, North America, Southeast Asia and other major markets. 【It does not contain harmful substances such as BPA and phthalates, and has passed food contact safety certifications including FDA and LFGB, so it can directly contact food packaging such as milk powder without safety risks.】
Suitable for packaging of adult milk powder, infant formula milk powder, goat milk powder, camel milk powder and other powdered dairy products
Adaptable to various specifications of iron cans, aluminum foil bags, composite paper cans and other packaging forms

Q1: Can this air cushion be customized for our specific milk powder can size?
A: Yes, we support full customization of size, thickness and structure. You only need to provide the diameter and height of your product, and our technical team will design a matching packaging solution for you, ensuring a perfect fit without leaving extra shaking space.
Q2: How long does it take to inflate a bag for one milk powder can?
A: When used with our Q20 air cushion machine, it only takes 2-3 seconds to inflate a single air column bag. The machine can inflate 15-20 meters of air column rolls per minute, which is fully suitable for large-scale production line packaging needs.
Q3: Is this material safe to directly contact with food-grade milk powder packaging?
A: All our materials have passed FDA, LFGB and other food contact safety certifications, do not contain any harmful substances, and can be safely used in direct contact with food outer packaging. For special requirements, we can also provide food-grade enhanced material options.
Q4: How about the moisture resistance effect in high humidity areas?
A: Our air cushion adopts a multi-layer barrier structure, and the water vapor transmission rate is only 0.5g/(m²·24h), which can maintain the dryness of the internal product even in high humidity areas with annual average humidity above 80%, and will not cause milk powder caking.
Q5: What is the minimum order quantity for customized products?
A: The minimum order quantity for standard size products is 1 roll (250m), and for customized size and printed products, the minimum order quantity is 5 rolls. We can provide sample testing services for bulk orders, and you can test the packaging effect before placing a large order.
Q6: Can this air cushion be recycled after use?
A: Yes, the product is made of single-component PE/PA composite material, which can be directly recycled and reprocessed into other plastic products, fully meeting the requirements of global plastic recycling regulations, and helping enterprises reduce carbon emissions in packaging links.
