Cartridge Paper

This is the name given to the good quality paper ~ of greater thickness and strength than normal ~ which is favoured by artists and draughtspeople for their work. The name goes back historically to the days when explosives were packed into paper tubes and used to expel pellets or bullets from guns. Such papers had to withstand rough handling to protect their contents as they were transported around in hunting bags or shooting-jacket pockets.

The manufacture uses longer longer fibres and stronger binding agents. The fibres are slightly more compressed than in office papers, and there is likely to be more attention paid to absorbency ~ by adding some size to the process. The surface usually has more bite ~ slight roughness ~ than office papers ~ which, nowadays, are given a smooth surface to perform well in office machinery.

Cartridge paper is invariably made to greater thicknesses ~ 120 or 140 gsm ~ than office paper ~ at 80 gsm. It is usually available in softer white and ivory tints as well as full white.

The UK paper manufacturers James Cropper has developed a cartridge paper called Cup-Cycling. To make this paper they collect used coffee cups ~ mainly from Costa Coffee shops ~ and remove the waterproof plastic liners ~ which are passed on for making electric cable insulation. The remaining paper fibres are sterilised ~ de-inked ~ and reprocessed into a good quality paper which is almost entirely free of printing inks and any other sign of their original use.
