How is a dunnage bag inflated?

Through an integrated valve using compressed air. The valve holds pressure during transport and opens in a controlled way at unloading.

Are dunnage bags reusable?

That depends on the version and its condition after transport. Heavier multi-ply versions are designed for repeated use, lighter variants are single-use.

DLP-1300: container dunnage bags

The DLP-1300 dunnage machine produces flat bags with valve that serve as air bags for cargo securing. These dunnage bags are placed between load units in a container and inflated with compressed air, preventing the cargo from shifting in transit.

What defines this machine

Valve technology at the core

The valve must inflate quickly, hold under sustained pressure and vent in a controlled way during unloading. It is positioned and sealed on the same machine.

Seams designed for sustained pressure

A dunnage bag is under internal pressure for the whole journey and additionally loaded by acceleration forces. Pulse sealing delivers reproducible seam strength for that duty.

Formats for common gap sizes

Dunnage bags are selected by the gap to be filled. Recipe management allows several formats without conversion.

High volume demand

Dunnage bags are consumables in large quantities. The 1300 frame with fully automatic cycle is built for series production.
