Last updated: April 2026 dataKraft sack paper is engineered specifically for multiwall bag and industrial sack construction, where high porosity, tear resistance, and controlled air permeability are critical performance requirements — properties that set it apart from general-purpose uncoated kraft grades. It is a primary input for cement bags, pet food packaging, flour sacks, and chemical product containers, making it closely tied to construction-materials and food-processing supply chains. Because sack paper specifications (porosity, elongation, grammage) are tightly defined by end-use standards, buyers and customs filers must ensure technical data sheets accompany shipments to support classification.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Kraft sack paper is characterized by high air permeability (porosity), elevated elongation at break, and specific tensile energy absorption values that allow bags to be filled at high speed without bursting. These properties — not just the kraft pulping process — are what distinguish it from general uncoated kraft paper and support its classification under SITC 64142.
The largest end-use sectors are cement and building materials (multiwall cement sacks), agriculture and food processing (flour, grain, and pet food bags), and industrial chemicals (bags for powdered or granular products). Demand in these sectors tends to track construction activity and agricultural output cycles.
