Kraft paper’s durability can be improved through specialized treatments that guard against wear and abrasion damage. Processes like saturation, coating, and wet strengthening transform standard kraft into abrasion resistant grades able to withstand demanding conditions.

Production starts with high-quality long fiber pulp to ensure a strong matrix of cellulose fibers. Refining aligns the fibers while pressing removes excess water, increasing paper density and toughness. Added minerals or chemicals boost surface strength. The paper may undergo calendering for a smooth, uniform finish.

Abrasion resistant kraft papers resist puncturing, scuffing, and rubbing wear. They outlast regular kraft in uses like construction flooring underlayment, furniture scratch protection, industrial filtration and gaskets. The durable paper also serves well for packing glass or metal materials to prevent transit damage.

For more extreme conditions, saturation with resins or polymers provides even higher abrasion resistance. Multi-ply laminations can also enhance durability. Treated kraft matches or exceeds the wear resistance of materials like light cardstock while retaining advantages like printability.

With the right manufacturing enhancements, kraft paper can exhibit remarkable ruggedness despite its fiber-based nature. Abrasion treatments unlock the raw durability within kraft to create papers ready for demanding tasks.
