This invention addresses the problem of providing a barrier paper packaging material having excellent gas barrier properties and water vapor barrier properties.

The barrier paper packaging material combines excellent gas-barrier properties with excellent water-vapor-barrier properties.

A barrier paper has a polymeric layer substantially covering a first side of the paper and an anti-blocking coating on a second side.

In addition to standard paper for flexible packaging, Koehler also presents its state of development of the innovative and sustainable barrier paper of the product line NexPlus.

In addition to standard paper for flexible packaging, Koehler also presents its state of development of the innovative and sustainable barrier paper of the product line Koehler NexPlus.

In addition to standard paper for flexible packaging, Koehler also presents the innovative development of a sustainable barrier paper for the Koehler NexPlus product line.

Barrier paper can be added to this as an extra precaution for works of higher value.

Making a barrier paper by coating it with MFC or NCC seems very promising, especially for oxygen resistance.

Thanks to the use of a special barrier-coated thermoformable paper, the overall weight of the trays has been reduced and around 40% less plastic is used.
