Types of Dunnage Air Bags
1. Kraft Paper Dunnage Bags
Kraft paper dunnage bags are made of multiple layers of extensible kraft paper. These bags are ideal for light to medium loads and are particularly popular due to their economical nature and recyclability. They can be used effectively for general freight and less-than-truckload (LTL) shipments, making them a versatile choice for many businesses.
2. Polywoven Dunnage Bags
Constructed from durable polywoven materials, these bags are suitable for medium to high-load capacities. They are designed for various modes of transport, including trucking, rail, and maritime shipping. Polywoven dunnage bags are moisture-resistant and can withstand challenging environmental conditions, making them a reliable choice for outdoor or humid environments.
3. Vinyl Dunnage Bags
Vinyl dunnage bags offer exceptional durability and are often used for heavy-duty shipments. Their puncture-resistant properties make them ideal for industrial applications. These bags are also weatherproof, providing additional protection for cargo exposed to the elements. They ensure that your goods remain secure and undamaged during transit.
4. Composite Dunnage Bags
These high-strength bags, crafted from a combination of polyethylene and polypropylene, are engineered for heavy loads. They are especially effective in containerized shipping and intermodal transport, where they help stabilize loads and prevent shifting. Their design allows for optimal void filling, creating a secure environment for your cargo.
Applications of Dunnage Air Bags
Dunnage air bags serve a variety of applications across different industries. Below are some of the most common uses:
1. General Freight
Dunnage air bags are widely used in general freight shipping. They cushion and stabilize loads, reducing the risk of damage during transit. Companies like www.abairbags.com and dunnagesystems.com offer a range of options suitable for various freight types.
2. Containerized Shipping
