PP Woven vs Kraft Paper Dunnage Air Bags Compared
Material and durability
The PP Woven bag has a woven polypropylene outer layer, offering high mechanical strength and good moisture resistance — suited to long-haul routes or high-humidity conditions. The Kraft paper bag uses multiple layers of Kraft paper, suited to dry cargo and general packaging applications.
Surface friction and positional stability
The Kraft bag typically has good surface friction, helping it stay in position when placed between cartons. The PP Woven bag has a smoother surface, but compensates with durability and moisture resistance.
Which one to choose
For long-haul ocean exports or humid environments, the PP Woven bag is generally the better choice. For dry cargo, shorter routes, or a preference for paper-friendly packaging materials, the Kraft bag can be a reasonable choice. The final decision should be based on an actual assessment of the shipment and route.
Frequently Asked Questions
Is the Kraft paper bag moisture-resistant?
The Kraft bag suits dry cargo and general conditions rather than routes with prolonged high humidity. For higher-humidity environments, the PP Woven bag is generally more suitable.
