The paper used in the production is the extensible Kraft refined at high consistency, natural or white color, which presents excellent mechanical properties and is fully constituted of virgin fiber coming from forests planted for this purpose.

In case of a need to provide a barrier for different permeates, such as oxygen and water vapor, an extruded plastic film can be added to the paper, milled or loose, to be in direct contact with the bagged product, or as an intermediary layer. In case of BACL and PBDS styles it is possible to seal the plastic film on the lower end.
