Process Introduction

40g glassine follows the same core process: high-fibrillation beating, AKD sizing, PVA surface sizing (4% concentration, 15-20 kg/ton), and supercalendering at 80-120°C with linear pressure 300-500 kN/m. The resulting paper has a mirror-smooth double-sided surface, oil absorption ≤1.1 g/m², and uniform density. After moisture balancing (24-48 hours, moisture variation ≤±0.5%), it is slit for silicone coating.

Uses & Distinguishing Features

  • Label Release Liner – For self-adhesive labels on bottles, jars, and retail packaging; clean release with no residue.

  • Courier Waybill Backing – Supports high-speed printing and die-cutting; tear-resistant.

  • Masking Tape Liner – Protects adhesive until application; stable under temperature changes.

  • Food Label Carrier – For ingredient labels on baked goods; moisture-proof.

Why Choose This Paper

40g meets standard industry requirements for general label applications, offering reliable release and die-cutting performance at a cost-effective weight.
