Dunnage a bags (also known as dunnage air bags or inflatable bags) are one of the most effective solutions to protect goods from damage during transportation and shipment. These airbags are designed to balance and secure cargo, providing maximum stability throughout the journey. ID (International Dunnage) Dunnage Bags are manufactured with an airtight polyethylene inner layer and a durable polywoven outer shell. They also include a reusable valve for practical use. Various dunnage bag types are available to suit different cargo needs and transportation methods. ID Dunnage bags are 100% recycable and can be used multiple times if used and stored correctly.
Dunnage Bag Types and Their Uses
Dunnage bag options offered by
ID Dunnage are categorized into five main types: Bison, L1, L2, L3–4, and L5. Each model is tailored to different load capacities and transport requirements, ensuring safe and efficient logistics operations.
Bison ID Dunnage Bag (Level 0)
Bison ID dunnage bag, also known as Level 0, is designed for lighter loads and is typically used in truck shipments. It is suitable for both vertical and horizontal gaps in vehicles. Equivalent to a 2-ply paper bag, it resists up to 2–3 PSI of working pressure. Among all options, Bison is the most affordable, making it ideal for budget-conscious shipping operations involving lightweight cargo.
Level 1 Dunnage Bag
Level 1 dunnage bag is one of the most popular and frequently chosen models. It is also equivalent to a 2-ply paper bag but supports heavier loads compared to the Bison model. Used in both truck and container transportation, it is effective in vertical and horizontal applications. With a maximum working pressure of 2–3 PSI, it delivers reliable protection for mid-weight cargo.
Level 2 Dunnage Bag
Level 2 dunnage bag expands beyond land transport and is suitable for ocean freight as well. It is widely used in trailers, containers, and rail systems, especially for international shipments. Equivalent to a 4-ply paper bag, it has a maximum working pressure of 6 PSI. It can be used in rail transportation for loads up to 34,000 kilograms (75,000 lbs), particularly in longitudinal gaps.
Level 3–4 Dunnage Bags
Level 3–4 dunnage bags are equivalent to 8-ply paper airbags and are engineered for transporting cargo weighing between 34,000 kg and 93,000 kg (75,000–205,000 lbs). These bags are ideal for rail transport and commonly used with products like plywood, bricks, and heavy paper rolls. They provide outstanding protection and fill large cargo spaces securely.
Level 5 Dunnage Bag
Level 5 dunnage bag is the most robust option, used for extremely heavy shipments. Designed for cargo exceeding 93,000 kilograms (205,000 lbs), it is especially suitable for railcars and ocean shipping. This model is often preferred for transporting items such as metal coils, bricks, and heavyweight paper rolls. It offers unmatched protection for the most demanding transportation conditions.
