Engineered for medium‑heavy dry food packaging, this 90 g/m² striped kraft paper provides enhanced burst resistance (≥3.2 kPa·m²/g) and stiffness. It is widely used for tea bags, dried fruit pouches, and snack bags, often combined with PE lamination for extra moisture barrier. The natural brown stripes evoke a traditional, eco‑friendly image.

Technical Specifications (QB/T 1706‑2006)

Process Introduction

Higher basis weight requires increased fiber furnish and slightly higher beating degree (30‑35°SR) to maintain strength. The pulp blend may include 5‑10% hardwood for better formation. The wire and press sections are run at slower speed to ensure uniform stripe formation at higher thickness. Single‑cylinder drying at 105‑115°C maintains moisture at 8‑10% to prevent brittleness. Optional surface sizing with PVA for enhanced water resistance.
