White Sack Kraft Paper

As our white paper grades are the brightest in the Advantage portfolio, they are in great demand from a huge variety of industries, ranging from food products to building materials. Optimal printability enables our customers to grab attention while offering the right packaging characteristics for the end-user.

Advantage Semi Extensible White Print is a calendered extensible sack kraft paper, combining high tensile energy absorption (TEA) and very good runnability with the excellent printability properties of a smooth finish paper. We especially recommend its use as an outer ply when high strength, best conversion properties and an brilliant appearance are required.

Benefits of our Sack Kraft Papers

  • Strength
    Both our brown and our white sack kraft paper grades offer excellent strength properties. Our strongest grades have a TEA index of up to 3.8 J/g. These grades are ideal for 1-ply and 2-ply industrial bags with a filling weight up to 50 kg.
  • Porosity
    For fast and dust-free filling of cement or other powdered goods we offer papers with a perfect combination of strength and porosity. These papers are porous enough to allow efficient de-aeration of bags during filling so that perforation is not needed. Yet they are strong enough to withstand the tough demands of filling and handling.
  • Printability
    Our white sack kraft paper grades in particular offer excellent print characteristics. A smooth paper surface and uniform paper formation achieve a high-quality print result that enhances your bag`s point-of-purchase appearance.
  • Runnability
    In the bag converting plant, paper features such as strength, stiffness and surface smoothness must be stable to ensure effective operation of the high-speed machinery.
