As the highest standard basis weight in common production (up to 90g per GB/T 29282-2024), 80 g/㎡ glassine paper achieves density ≥1.10 g/cm³ and smoothness ≥1000s. It is engineered for heavy-release applications: industrial adhesive liners, foam tape carriers, and moisture-proof packaging. Thickness 0.09-0.10 mm provides excellent stiffness for automated dispensing.

Process Introduction
80g glassine requires specialized supercalendering with multiple nips to achieve high density without losing formation. The base paper is made from 100% long-fiber softwood pulp with intensive beating (30°SR). PVA surface sizing is applied at higher coating weight to seal the surface. Supercalender linear pressure reaches 500 kN/m at 120°C. The finished paper has a glass-like finish on both sides, with oil absorption ≤1.1 g/m².
Uses & Distinguishing Features
Heavy-Release Liner – For industrial adhesives, structural tapes, and double-sided foam tapes.
Pharmaceutical Packaging – Moisture-proof liner for blister packs and transdermal patches.
Hot Stamping Base Paper – Smooth surface for foil stamping and high-end printing.
Food Contact Release – For baking parchment and candy tray liners (FDA compliant).
Why Choose This Paper
80g delivers maximum density and strength for the most demanding release liner and industrial packaging applications where durability is paramount.
