Abstract
A method of manufacturing an ink cartridge assembly including applying plastic foils to opposite surfaces of a sheet of foam while heating the foils to a temperature above the melting temperature of the foils using a heating press, stamping out a foam body from the sheet, and inserting the body into an ink cartridge housing. Alternatively, the surfaces are covered with a perforated or porous varnish coating or with composite foils of first and second layers having different melting temperatures where the layer with the lower melting temperature is disposed against the sheet of foam.
