80gsm High Smoothness Surface Uncoated Woodfree Printing Paper Offset Paper Bond Paper
Bond paper is a high-quality durable writing paper similar to bank paper but having a weight greater than 50 g/m2. The most common weights are 60 g/m2 (16 lb), 75 g/m2 (20 lb) and 90 g/m2 (24 lb). The name comes from its having originally been made for documents such as government bonds. It is now used for letterheads and other stationery and as paper for electronic printers. Widely employed for graphic work involving pencil, pen and felt-tip marker, bond paper can sometimes contain rag fibre pulp, which produces a stronger, though rougher, sheet of paper.
