How is PP Woven different from a Kraft bag?

The PP Woven bag has a woven polypropylene outer layer, offering better mechanical strength and moisture resistance than the Kraft bag (multi-ply paper outer layer). Kraft suits dry cargo; PP Woven suits shipments needing greater durability or more humid transport conditions. See the comparison table below.

Can this be used for 20ft and 40ft containers?

Yes. PP Woven dunnage bags are used for both 20ft and 40ft containers as well as some other transport modes, with the specific size determined per shipment.

Is special inflation equipment required?

Inflation should follow the instructions and pressure appropriate to each product's specification. CARGENTRA provides specific usage guidance as part of the quotation.

Can a PP Woven bag be reused?

Reusability depends on the bag's condition after deflation and actual usage conditions. Careful inspection is recommended before deciding to reuse a bag.

When should I choose PP Woven over Kraft?

When a shipment needs higher mechanical strength, more frequent handling, or an ocean route with higher moisture-resistance requirements, PP Woven is typically more suitable than Kraft.

Why Does Cargo Shift Inside a Container?

Void space between pallets or cargo units, combined with continuous vibration, acceleration/braking, direction changes, and handling at ports, are common causes of cargo shifting inside a container throughout transit.

Dunnage air bags fill these voids, creating a holding force that helps restrict movement throughout transit.

How Does a Container Dunnage Bag Work?

The bag is placed into the void between cargo units and inflated to an appropriate level to create a contact surface that helps keep cargo stable throughout transit.

1Measure the void
2Select a suitable bag
3Position the bag
4Inflate and inspect

Safety note: do not over-inflate. Always follow the specification of each product line.

PP Woven Dunnage Air Bag Construction

A dunnage air bag with a woven PP outer layer, offering good mechanical strength and moisture resistance suited to ocean freight conditions. Commonly used to fill voids between pallets, or between cargo and container walls, to restrict movement throughout transit.

A woven polypropylene outer layer is a material commonly used in applications requiring greater mechanical strength than a paper layer. This is why PP Woven bags are typically considered for shipments needing greater durability or more demanding transport conditions — the specific fit should be confirmed against each size specification as part of the quotation.

Applications by Industry

Electronics & Home Appliances

Electronics are sensitive to shock and humidity, and can suffer component or packaging damage if not properly secured.

Industrial Machinery

Industrial cargo is often heavy, and can shift with significant force if not properly dunnaged.

Consumer Goods

Cartoned consumer goods are prone to toppling and crushing when stacked in multiple layers inside a container.

Logistics & Warehousing

Logistics and 3PL companies handle a wide mix of cargo, and need flexible dunnaging approaches tailored to each shipment.

PP Woven vs Kraft Paper

Criteria	PP Woven	Kraft Paper
Outer material	Woven polypropylene (PP)	Multi-ply Kraft paper
Handling considerations	Good mechanical strength, suited to more frequent handling	Good surface friction, helps hold position in place
Moisture environment considerations	Moisture resistance suited to ocean freight conditions	Suited to dry cargo; not the priority choice when high moisture resistance is needed
Typical applications	Cargo-securing needs requiring greater durability, ocean routes	Dry packaging, shipments without a high moisture-resistance requirement
Selection considerations	Higher durability/moisture-resistance needs, more demanding transport conditions	Dry cargo type, budget, void size to fill

How to Use a Dunnage Air Bag

1Measure the void that needs to be filled.
2Position the bag correctly between cargo surfaces.
3Inflate following instructions and the appropriate pressure.
4Inspect the contact surface and stability after inflation.
5Do a final check of the overall cargo arrangement before closing the container doors.

Frequently Asked Questions

A PP Woven dunnage bag is placed into the void between pallets or between cargo and the container wall, then inflated to create a contact surface that helps secure cargo throughout transit — particularly suited to ocean routes and shipments requiring greater durability.
