Description

This 21 g/㎡ roll tissue paper provides heavy‑duty interleaving protection for industrial applications – between glass sheets, metal plates, and finished hardware components. Higher basis weight (21g) gives increased tear resistance (tear index ≥3.0 mN·m²/g) and stiffness. The paper is acid‑free and sulfur‑free, preventing tarnish on silver or copper parts. Available in roll widths up to 1092 mm and lengths from 30 to 840 meters.
