Woodfree Paper
CHINA UV PAPER

Woodfree paper is produced from 100% premium bleached chemical wood pulp on an uncoated, low-filler route: even fibre distribution, a fine smooth surface, high and stable brightness, and no show-through in double-sided printing — the classic choice for exercise books, textbooks and business stationery.

The range covers the full 55–120 g/m² series in high-white and natural shades; standard cut sheets are 787×1092 mm and 889×1194 mm, with reel widths customised to each customer's press, supporting both small trial orders and large-volume stable supply.

Applications: exercise books, notebooks, textbooks and teaching materials, ledgers and forms, envelopes and letter paper, office copier paper, leaflets, invoices and vouchers.

Advantages: brightness 98–103% (ISO) with opacity ≥92% for crisp double-sided printing; high surface flatness for high-speed web offset and sheetfed presses; moderate sizing so fountain, gel and ballpoint pens write cleanly without strike-through or bleed; MD tensile ≥4 km for durable bound volumes.
