Kraft Liner Board

Kraft Liner Board is a type of paperboard made primarily from sulfate pulp (kraft pulp), characterized by high strength, bursting strength, and water resistance. It is commonly used to manufacture the top and bottom layers of corrugated boxes. In foreign trade, this term typically appears in import and export contracts for paper products and packaging materials, serving as a commodity description, specification indicator (such as grammage, thickness, bursting index), and pricing basis. Usage scenarios include: inquiring with overseas suppliers, signing procurement contracts, goods description in letter of credit terms, and commodity declaration for customs clearance and inspection. Notes: 1) It is necessary to clearly distinguish 'Kraft Liner Board' from 'Kraft Cardboard' and 'Corrugated Board'; the former is a single or double-layer rigid paperboard, while the latter is a multi-layer structure processed with corrugation; 2) In trade, key parameters such as grammage (g/m²), moisture, and bursting strength should be specified to avoid disputes arising from specification discrepancies; 3) Pay attention to differences in national standards, e.g., the US commonly uses 'Kraft Liner' to refer to top liner, while Europe may use 'Test Liner' for imitation kraft liner board, so the specific grade must be clearly stated in the contract.
