In modern logistics, proper cargo securing is essential to prevent damage, reduce financial loss, and ensure safety during transportation. A dunnage bag (also known as an air bag) is placed in the void spaces between cargo to stabilize and immobilize goods inside containers or trucks. By absorbing shocks and preventing load shifting during transit, dunnage bags significantly reduce the risk of product damage, pallet collapse, and container imbalance. They are widely used in export shipments where long-distance sea or land transport increases the chances of cargo movement.

A composite strap is a high-strength strapping solution made from polyester fibers coated with polymer. It offers excellent tensile strength, flexibility, and resistance to weather conditions, making it ideal for securing heavy pallets, machinery, timber, and industrial goods. Unlike traditional steel strapping, composite strap does not rust, is safer to handle, and can absorb impact without snapping easily. This elasticity helps maintain consistent tension even when cargo settles during transportation, providing reliable load stability.

An edge protector plays a crucial supporting role by distributing the tension pressure from straps across a wider surface area. When straps are tightened directly onto cartons or palletized goods, sharp edges can cause strap damage or product deformation. Edge protectors prevent corner crushing, improve stacking strength, and enhance overall load integrity. When used together—dunnage bags to fill gaps, composite straps to secure loads, and edge protectors to protect corners—these materials create a complete cargo securing system that minimizes transit damage and ensures safe delivery.
