Process Introduction
Similar to the 80g grade but using a slightly heavier base paper. The paper is coated with a higher‑solids adhesive to ensure deep penetration into thicker spines. Drying temperature is precisely controlled to maintain stiffness without brittleness. Slitting widths are optimized for large‑format books (35‑50mm). Each roll is tested for thickness consistency and fold endurance.
