Kraft paper is a type of paper with relatively high strength produced by the kraft process (sulfate pulping), named after the German word 'Kraft,' meaning strength. In foreign trade, the term usually refers to unbleached or bleached kraft paper, with a grammage generally ranging from 40 to 200 g/m². It features high burst strength, tear resistance, and good air permeability, and is widely used for packaging, bag making, envelopes, and linerboard for corrugated cardboard. Application scenarios include export packaging materials, cultural paper, and industrial paper. Notes: Specifications must be clearly stated (grammage, width, roll or sheet), whether it is bleached (unbleached is brown, bleached is white), whether it contains recycled pulp, and burst index, etc.; it differs from 'Kraft Liner,' which specifically refers to the top layer of corrugated cardboard and usually has a higher grammage; and from 'imitation kraft paper,' which may contain other pulps or dyes and has lower strength. Foreign trade contracts should specify the exact grade and standard of Kraft Paper (e.g., ISO, TAPPI) to avoid disputes caused by ambiguous terminology.
📝 Examples
1. We need to purchase 100 tons of unbleached kraft paper, 80 g/m², roll width 1600 mm. Please quote your best CIF Shanghai price. (Note: Specify specifications, quantity, and trade terms for inquiry.)
2. The contract stipulates that the burst index of the kraft paper shall be no less than 3.5 kPa·m²/g. If SGS inspection at the port of arrival shows non-compliance, the buyer has the right to claim compensation. (Note: Emphasize quality indicators and inspection clauses for contractual quality terms.)
