Description

150 g/m² butter paper is a super‑heavyweight grade (basis weight tolerance ±5%) used for archival wrapping of fragile documents, rigid structural crafts, and die‑cut templates. Transparency is approx. 55% (interpolated), providing a frosted glass effect. Exceptional tear resistance (≥450 mN) and low stretch (MD 4.5%) ensure long‑term dimensional stability, making it ideal for preservation and repeated handling.

Process Introduction

150g paper requires a specialized approach with extended beating (≥95°SR) to maintain translucency at high basis weight. Multiple refining passes ensure full fiber hydration. The web is formed on a cylinder or slow Fourdrinier machine. Pressing uses graduated pressure to avoid fiber crushing. Drying is carried out in multiple zones (60‑80°C, then 80‑100°C). Semi‑dry calendering at 130 kN/m is followed by surface sizing with formaldehyde‑free biological glue. Final moisture carefully balanced to 6‑8% to prevent edge curl.

Applications & Advantages by Category

  • Archival Wrapping – Acid‑free, protects ancient maps, manuscripts, and photographs from light and dust.

  • Structural Crafts – Foldable enough for 3D geometric lamps, yet rigid enough to hold shape.

  • Die‑Cut Templates – Heavy weight resists tearing when cutting around complex shapes.

  • Transparent Partition Sheets – For museum display or office dividers with frosted aesthetic.

Why Choose This Paper

150g offers near‑board strength with translucent beauty – perfect for preservation specialists and advanced crafters.
