Abstract: Bleached absorbent Kraft base paper is highly specialized paper used for manufacturing of expensive decorative laminates and paper phenolc copper clad (PPCC) which is commercially known as pictorial circuit board. No filler loading and pulp beating is required in this paper. A furnish ratio of mill pulp having pine, bamboo and eucalyptus in the ratio of 1:2.3:11 and softwood being 1:1 is found to be suitable for manufacturing of bleached absorbent kraft base paper and fulfil all the requirements like water klemn, COP, tear strength, opacity, and brightness. One per cent MF resin dose at pH 6.17 is optimum to get specified value for cross-linking. The paper should be calendered to get a thickness between 280-310 μm and porosity 2300-2700 mL/min. No BIS specification is available; hence specifications from leading decorative laminates and PPCC were collected. The final results of laboratory made hand sheets are compared with specifications prescribed by leading manufacturers of PPCC and bleached Kraft and mill made bleached absorbent paper. The results are promising, which tempted the Indian paper makers to develop it indigenously.
