65g/m²
80g/m²
Cut-size copier paper, 65 to 80 g/m², specified to ISO methods throughout.
Copier paper is judged on what it does not do: jam, curl, or show the previous page through. Opacity at 88 % or better is what stops show-through on duplex work, and moisture held at 4.5 % ±1.0 is what keeps the ream flat and the feed reliable.
Testing is dual-referenced to Chinese GB and ISO methods — grammage to GB/T 451.2 and ISO 536, brightness to GB/T 7974 and ISO 2470, opacity to GB/T 1543 and ISO 2471.
Typical applications — Office copier and laser printing, cut-size reams, digital print

Figures are typical values from mill technical data, not a guaranteed specification. We agree the binding specification with you before the mill runs.
The weights we run are 65 · 80 g/m². Reel width is slit to your line; anything outside this list depends on the mill and the run, and is confirmed with the quotation.
Reels or sheets — slit to your line width.
Full technical data sheet and batch test report on request.
Send the basis weight, the reel width and the monthly volume. You get a quotation from someone who knows the mill, usually within one working day.
