Protective Dunnage Bags for Cargo Security

The importance of cargo security extends beyond just the physical goods; it also impacts product and brand image. If a load arrives at the customer with scattered products, inclined stacks, or, in the case of liquid products, spills and leaks, it may damage a brand’s reputation. In the current business climate, perhaps more than ever, the potential losses from such incidents can seriously impact a brand’s credibility and, ultimately, sales. To prevent these issues, Logimarkt’s protective dunnage bags for cargo offer a simple and effective solution.

These dunnage -or air bags for packing- are suitable for multiple types of transit. These include trucks, railcars, sea containers, and oceangoing vessels. The dunnages are not recommended for air cargo due to the risk of bursting under high-altitude pressure.

Logimarkt’s protective dunnage bags are constructed from Poly-woven material. It was chosen for its flexibility and cost efficiency compared to kraft paper options. These bags are designed for reuse, recommended for up to four uses.

Our production process involves meticulous quality checks to ensure the reliability of our dunnage bags:

• Valves undergo leakage tests before being sealed.
• Each bag undergoes a 15-minute flat-wall test to ensure no loss of air pressure.
• Material is tensile tested before sewing to guarantee high quality.
• Bags are randomly tested for burst pressure during production to confirm their strength.
• Each bag is barcoded for full traceability before and after production.

These dunnage bags feature an air-tight polyethylene inner layer and a reusable valve for both inflation and deflation, with an outer layer made from durable polywoven material.

We offer a range of dunnage bags to meet your specific needs, depending on the material strength required and the mode of transportation. Multiple dimensions are available for each product type.

In designing our dunnage bags, we consider several factors, including the distance between cargo stacks. For voids up to 30 cm wide, we offer a range of bags:

• Standard dunnage bags
• Category A dunnage bags
• Category B dunnage bags
• Category C-D dunnage bags
• Category E dunnage bags

Our team can recommend the appropriate fabric strength and sewing method for each project. These are recommended based on the size, weight and type of cargo, as well as the type of transport, stack spacing and cargo handling requirements.

For voids wider than 30 cm, we recommend the following items, that ensure optimal protection for larger spaces:

• Big dunnage bags
• Double dunnage bags

Properly installing dunnage bags is essential for securing cargo effectively. Here are three basic steps to follow when using our protective dunnage bags:

1. Placement of the Dunnage Bag:
   • Position the empty dunnage bag in the void space that needs to be filled to secure the cargo.
   • Ensure that the void left does not exceed 30% of the total gap. The dunnage bag should fill at least 70% of the space for optimal security.
   • If the cargo has sharp edges, protect the dunnage bag by placing buffer material around these edges. This precaution prevents damage to the bag during transport, ensuring it remains effective in securing the cargo.

1. Proper Positioning of the Bag:
   • Arrange the dunnage bag so that it doesn’t touch the floor. There should be a minimum clearance of 3 cm from the ground.
   • Additionally, make sure the bag does not extend beyond the top or sides of the load. Proper positioning is crucial to avoid any undue stress or damage to the bag.
2. Inflating the Bag:
   • Begin inflating the bag with air. It’s important to closely monitor the air pressure and not exceed the working air pressure specified for the type of dunnage bag you are using.
   • Once the bag reaches the required working air pressure, remove the inflator tool from the valve.

Following these steps ensures that the protective dunnage bags are effectively utilized to secure your cargo, minimizing the risk of damage during transit.

Best Practices and Recommendations for Using Logimarkt’s Protective Dunnage Bags for Cargo

Understanding the best practices for using our protective dunnage bags can significantly enhance cargo security during transit. Here are some essential tips and tricks:

Intermodal Transport Considerations:

• In intermodal transport involving different transportation modes (e.g., truck, rail, sea container) without cargo handling, use dunnage bags to fill lateral voids rather than lengthwise.
• Avoid using dunnage bags in spaces between the container’s doors or walls and the load.

Air Cargo and Hazardous Materials:

• Dunnage bags are not suitable for air cargo due to the risk of bursting under high altitude pressure.
• They are also not recommended for the transport of hazardous materials.

Handling Dunnage Bags – Dos and Don’ts:

Dos:

• Ensure your inflator tool has a pressure gauge and is used according to approved instructions.
• Always stand to the side of the dunnage bag during inflation, wear eye protection, and maintain a steady footing.
• Adhere to the pressure limit for each dunnage bag type. Recheck the pressure after 30 minutes since polywoven bags may lose pressure when stretching. Re-inflate if necessary.
• Place dunnage bags at a minimum height of half the upper layer between stacks to maintain their position.
• Use corrugated cardboard on both sides of the dunnage bag to prevent slipping during transit. Inflate the bag so that it and the cardboard sheet are firmly in place.

Don’ts:

• Do not place dunnage bags next to each other in the same lengthwise space.
• Avoid perforating dunnage bags with sharp objects for deflation. Instead, use the spring dial on the valve.
• Do not store dunnage bags in dusty or wet environments. Keep them in the original boxes they were delivered in for optimal preservation.

Following these guidelines will help ensure that protective dunnage bags are used effectively. It further maximizes cargo security and minimizes risk during transport.
