    Kraft Paper

    Kraft Paper, the most used Packaging Material is majorly produced through the Sulphate Pulping process. Paper has historically been made from a variety of materials including Hemp, Cotton, Sugarcane Bagasse, and Straw. Nowadays, Paper is mostly made from Wood-based Cellulosic Fiber. Kraft Paper, a very high-strength Packaging Paper, is made from unbleached or bleached Sulphate Pulp or Equivalent Fibers. Sometimes, semi-chemical Pulp is also used in its Production. High-Strength and Moisture Resistant Kraft liner is used as an Outer and Intermediate Ply, especially in Corrugated Boards. Kraft paper’s strength makes it suitable for Paper Bag Production.

    Paper being Plant Fiber based is Hygroscopic in nature with a tendency to swell. Improper Storage or cargo care can result in Dimensional changes, Distortion, and Reduced strength (tearing). Paper Rolls are very sensitive to Mechanical influences such as Pressure, Impact, and Friction. The Risk of Damage is greatest during Cargo Handling. As such, the Kraft Paper Quality needs to be examined before its use as Packing material. Else, the purpose of use may not be served..

    EFRAC’s superior Technological Infrastructure and Skilled Manpower puts it at the forefront in Packaging Testing Domain in India. .
