Brown Sack Kraft Paper

In order to give our brown paper grades the best possible strength properties, they are made out of virgin fibre from slow-growing pine and spruce. With efficient converting in mind, our paper is the ideal choice for a wide range of applications, such as sacks for cement & building materials, food and animal feed.

Advantage Semi Extensible is a brown extensible sack kraft paper combining high tensile energy absorption (TEA) and excellent runnability. We especially recommend its use when high strength and best conversion properties are required. Advantage Semi Extensible is also available in wet strength quality.

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.
