Electroscopic material packaging

A system for producing enveloped electroscopic filter material, comprising:

• a main spool configured to receive at least one sheet of electroscopic filter material and to feed the electroscopic filter material in a first direction;
• a pair of spools configured to receive sheets of cover material and to feed the sheets of cover material in the first direction such that each spool feeds cover material along a different side of the electroscopic filter material;
• a pair of heat sealing roller nips configured to periodically seal the at least one sheet of electroscopic filter material and the sheets of cover material to form sealed portions;
• a cutting mechanism configured to cut each sealed portion to produce envelopes of electroscopic filter material, wherein the at least one sheet of electroscopic filter material extends to the outermost edges of each envelope such that each envelope comprises has the same dimensions as the at least one sheet of electroscopic filter material.

An article for storing electroscopic filter material comprising:

• at least one sheet of electroscopic filter material;
• a first sheet of cover material covering a first side of the at least one sheet of electroscopic filter material;
• a second sheet of cover material covering a second side of the at least one sheet of electroscopic filter material,
• wherein the at least one sheet of electroscopic filter material, the first sheet of cover material, and the second sheet of cover material each extend to the perimeter of the article and the perimeter of the article is heat sealed.
