Stock - The paper base stock shall normally be free from
24、 more than trace amounts (less than 1%) of unbleached pulps, except that no limitation is imposed on the amount of deinked or non-deinked bleached secondary (recycled) fibre, nor on the amount of high-yield pulps present in the stock. Fluorescent (optical) brighteners may be present. Moisture Conten
25、t - This paper may be used either in air-conditioned pressrooms or in pressrooms lacking relative humidity and temperature controls.

29、ed on a squaring table. The edge bow in individual sheets shall not be more than 0.8 mm in each 762.0 mm, as determined by turning a sheet over, butting an edge against the corresponding edge of the sheet below, measuring the gap between them, and taking half of this measurement. Width (rolls) - The
30、 rolls shall be a width as specified (par. 8.1) with a tolerance of 0.8 mm. Cores (rolls) - The paper shall be wound on a non-returnable core which has an inside diameter as specified (par. 8.1). The cores shall be of fibrous material, and shall have a wooden, metal or plastic bung at each end. Gram
