Description

Designed for applications requiring minimal basis weight without sacrificing barrier performance, 30 g/㎡ glassine paper achieves a density of ≥1.00 g/cm³ through intensive supercalendering. With transparency of approximately 55% (estimated), it serves as an economical release liner for low-adhesion tapes, light-duty die-cutting, and interleaving for delicate components. Made from 100% bleached sulfate wood pulp, it is free of fluorescent agents and fully biodegradable.

Process Introduction

30g glassine paper starts with 70-80% softwood and 20-30% hardwood bleached sulfate pulp, beaten to high fibrillation (softwood 22-30°SR, hardwood 22-26°SR). AKD sizing (1.5-2.0%) and cationic starch (0.8-1.0%) are added. Web forming at 0.5-1.0% consistency, pressed to 40-45% dryness, pre-dried to 7-8% moisture. Surface sizing with 4% PVA at 15-20 kg/ton. Supercalendered with 10-12 alternating steel and fiber rolls at 80-120°C, 300-500 kN/m, achieving density ≥1.00 g/cm³ and smoothness ≥600s. Moisture balanced for 24-48 hours, then slit.

Uses & Distinguishing Features

  • Light-Duty Release Liner – For low-tack labels, price tags, and stationery tape backing; stable release force.

  • Electronic Interleaving – Separates thin films, touchscreen protectors, and flexible circuits during storage.

  • Confectionery Wraps – Non-stick inner wrap for chocolates and caramels; high transparency shows product.

  • Medical Plaster Liner – Lightweight release paper for small bandages and dressing strips.

Why Choose This Paper

30g is the lightest glassine available, reducing material consumption while maintaining high density, transparency, and release performance for non-demanding applications.
