Product Description

Copy paper

This premium copy paper is manufactured from 100% virgin wood pulp, delivering exceptional print quality, consistent performance, and reliable feeding in all office printers and copiers. Available in standard sizes including A4 (210×279 mm), A3 (420×279 mm), Letter (216×279 mm), and Legal (216×356 mm), this paper suits a wide range of office, educational, and professional applications. Offered in 70, 75, and 80 gsm weights, each sheet is precisely engineered with a caliper of 104 μm (±2) for optimal stiffness and smooth handling. The paper features excellent surface smoothness with roughness values below 300 ml/min, ensuring text, vivid graphics, and reduced jamming. Whiteness levels of 146-168 CIE provide bright, crisp contrast for clear, professional-looking documents, while opacity above 91% prevents show-through for double-sided printing.

Engineered for durability and high-volume use, this copy paper offers strong mechanical properties with MD stiffness exceeding 105 mN and CD stiffness above 45 mN, ensuring reliable performance during printing and handling. The high ash content (>18%) enhances opacity and print contrast, while the low moisture content (3.9-5.3%) ensures dimensional stability and prevents curling. Cobb 60 values of 20-30 gsm provide controlled absorbency for fast ink drying without smudging, and the Dennison surface strength above 14 ensures consistent toner and ink adhesion. Packaged in reams of 500 sheets with 5, 8, or 10 reams per box, this paper supports secure, convenient storage. Custom OEM/ODM logo and packaging services are available. Whether for daily office use, professional presentations, or educational materials, this copy paper delivers reliable, consistent performance and professional-quality output.
