120 g/m² butter paper is the heaviest standard grade in common use, with tearing resistance ≥350 mN and transparency 60%. It is engineered for demanding tasks: PCB hand drawing, industrial insulating gaskets, rigid document covers, and high‑end translucent packaging that must withstand handling. The double‑sided matte finish allows writing and printing on both sides.

Process Introduction
120g paper uses a maximum fiber refining degree (≥95°SR) to ensure fiber flattening and air expulsion. The pulp is formed at very low consistency (0.6‑0.8%) to achieve uniform formation. Pressing with moderate linear pressure prevents fiber collapse. Primary drying at 60‑70°C for slow shrinkage. Semi‑dry calendering at 120 kN/m at 12‑15% moisture. Surface sizing with high‑concentration PVA for superior water and oil resistance. Secondary drying to 6‑8% moisture, then finishing calendering.
Applications & Advantages by Category
PCB Hand Drawing – Durable, dimensionally stable for circuit board master drawings.
Industrial Insulating Gaskets – Used as dielectric barrier in electrical equipment (check voltage rating).
Rigid Document Covers – Protects blueprints, maps, and certificates; translucent for easy identification.
High‑End Packaging – Wraps watches, jewelry, or fine pens; robust and elegant.
Why Choose This Paper
120g delivers the highest tear strength and stiffness, making it the choice for industrial and premium packaging applications.
