  • What is …

    … a paper dunnage bag?

    A paper dunnage bag consists of three components.

    The first component is an air-filled inner bag (Inliner), responsible for density.

    The second component is an outer bag made of one or more kraft paper layers, responsible for strength: the more layers the stronger the dunnage bag.

    The third component is our especially developed and self-closing valve ensuring an easy filling at high density.
  • Material

    The outer layers consist of semi-extensible kraft paper.

    The Inliner consists of coextruded polyethylene (PE).
  • Additional information

    Dunnage bags were developed at the beginning of the 1970ies as comfortable, easy to handle and cost-saving alternative for securing and stabilizing freight in ISO-containers. They are placed in stowage gaps and absorb dynamic loads during transport through compression.

    An exact analysis of your application (dimensions and weight of freight, carrier, transport routes, climatic conditions) allows us to recommend the ideal dunnage bag with the best cost-saving factor.
