0.45mm-4.0mm Grey Backing Board High Stiffness Laminated Recycled Paper

Material Composition
Crafted from 100% recycled pulp fibers, this grey board undergoes precision drying to achieve a uniformly fine surface texture, moderate smoothness, and exceptional dimensional stability.

Physical Properties
Structural Integrity: High stiffness (≥15° bending resistance) and remarkable toughness, resisting deformation under stress.
Surface Quality: Flat, neat appearance with consistent thickness tolerance (±0.05mm).

Functional Performance:
Uniform ink absorption for precise print registration;
Tensile strength ≥4.5 kN/m;
Folding endurance >100 double folds (MIT tester).
