With A Specialized Valve Selection That Ensures Zero Air Leakage, JahooPak PP Woven Dunnage Bags Are Engineered To Stabilize Heavy Pallets, Deep Container Gaps, And Sensitive Thermal Cargo, Making Them The Trusted Choice For Global Logistics Leaders Like Maersk And Coca-Cola.

Precision Fit for Wooden Crates and Irregular Gaps.
This image demonstrates the ideal application of our white PP woven bag for securing large wooden crates in shipping containers.
Key Usage Scenarios:

• Ideal for filling the vertical spaces between heavy wooden shipping crates that lack smooth, flush surfaces.
• Perfect for isolating separate palletized loads within the same container, preventing them from colliding during transport.
  Major Advantages:
• Uniform Expansion: Unlike stiff wood shoring, the bag expands gently but firmly into the irregular spaces around the crates’ cross-bracing, ensuring 100% gap contact.
• Anti-Scratch Protection: The smooth woven outer layer acts as a soft barrier, protecting the raw wood surface from being scraped or gouged by metal container walls.
• Optimized for Heavy Loads: Engineered to withstand the immense weight and outward thrust of tightly packed wooden crates, keeping them perfectly aligned throughout the journey.

Rapid On-Site Inflation with Portable Equipment.
This real-world scene illustrates how seamlessly our dunnage bags integrate into daily logistics operations, utilizing our efficient inflation tools.
Key Usage Scenarios:

• Used directly on the loading dock, inside the container, or in the warehouse before the truck departs.
• Applicable to any packing station equipped with a standard air compressor or our specialized portable inflators.
  Major Advantages:
• Time-Saving Workflow: The quick-docking valve design allows workers to connect the pneumatic gun in under 2 seconds, drastically reducing the time required to secure an entire container load.
• Effortless Handling: The portable nature of the inflator gun allows the operator to easily maneuver around tight corners and awkward gaps within the container.
• Flexible Control: Operators can visually observe the bag’s expansion and stop inflation at the optimal pressure, ensuring a perfect balance between holding force and cargo safety, without risk of over-inflation.

Versatile AAR-Graded Models for Every Load Requirement.
Our portfolio offers a comprehensive range of standard models, graded from Zero to Four, to match your exact shipment weight and protection needs.
Key Usage Scenarios:

• Level 0-1 (Light to Normal): Perfect for filling lateral voids in boxcars, trailers, and sea containers carrying moderately heavy goods.
• Level 2-4 (Heavy to Ultra-Heavy): Required for lengthwise void fillers in railcars and containers carrying massive payloads ranging from 75,000 lbs to over 205,000 lbs.
  Major Advantages:
• Easy Selection: The clear categorization allows logistics managers to instantly pick the correct bag model based on the specific cargo weight and transport mode (Sea vs. Rail).
• Customization & Flexibility: In addition to the standard models, we offer total customization in length (within 50-150cm width) and full OEM branding capabilities.
• International Compliance: Every bag comes with AAR, SGS, and MSDS certifications, guaranteeing they meet the strictest safety and quality standards required for global heavy-duty logistics.

Superior PA+PE Composite Film for Ultimate Airtightness.
This close-up view reveals the high-quality engineering hidden inside every JahooPak bag: a 0.20mm thick PA (Nylon) and PE composite inner liner.
Key Usage Scenarios:

• Essential for long-distance sea freight and cross-continental rail journeys, where consistent air pressure must be maintained for weeks.
• Critical for protecting sensitive moisture-prone cargo, where the inner film prevents external humidity from entering the bag and causing pressure instability.
  Major Advantages:
• Zero Air Leakage: The precise 0.20mm thickness combined with the PA+PE material creates an exceptional gas barrier, keeping the bag fully firm from origin to destination without the need for repeated re-inflation.
• Maximum Durability: This high-tensile film is flexible enough to expand into tiny gaps, yet strong enough not to burst under maximum recommended working pressures.
• Proven Reliability: The detailed thickness inspection guarantees the consistent performance and long-life reusability that our global clients have trusted for over a decade.
