Description

Designed for demanding die-cutting and insulation applications, 70 g/㎡ glassine paper achieves a thickness of approximately 0.075-0.085 mm with tensile strength MD ≥6.00 kN/m. It serves as a stable base for cutting mobile phone accessory pads, dustproof gaskets, and thermal insulation sheets. High density prevents fiber lifting during kiss-cutting.

Process Introduction

70g glassine undergoes extended supercalendering to maintain density and smoothness at higher basis weight. The fiber furnish uses premium bleached softwood kraft pulp. Multi-stage pressing ensures uniform caliper. PVA surface sizing (4-6% concentration) is applied on both sides. After supercalendering, the paper is moisture-balanced for 48 hours to prevent edge curl. Optional anti-static treatment (surface resistance 10⁸-10¹¹Ω) is available.

Uses & Distinguishing Features

  • Electronic Die-Cutting – Base paper for smartphone gaskets, speaker mesh, and camera lens protectors.

  • Insulation Gaskets – For small appliances and battery compartments; dielectric strength.

  • Adhesive Tape Liner – Heavy-duty tapes for automotive and industrial use.

  • Anti-Static Packaging – Wraps sensitive electronic components (with anti-static treatment).

Why Choose This Paper – 70g provides the structural integrity needed for precision die-cutting without deformation, making it a top choice for electronics component manufacturers.
