Weighing paper is often used when weighing solid, powdery substances on an analytical balance. By preventing the substance from making contact with unwanted materials, the precision of the measurement may be increased.
The weighing paper is usually made through the process called calendering. First, a chemically manufactured paper pulp fiber is broken down and squeezed into the mold where it will dry into the sheet. Then, this sheet will be rolled down by hot roller. As a result, the pulp fiber will be flat and in the same direction. To make the paper very smooth and moist-resistant, it goes through the process repetitively, called super-calendering.
Weighing paper can be folded into different shape depending on its uses.
The weighing paper is provided in different sizes : 6in by 6in, 4in by 4in, and 3in by 3in.
