The raise of economic development in the Asia brings increment to the consumption rate of the people. As more goods consumed so does the waste production including paper, either as packaging materials or other purposes. The condition also raises the awareness of people for reducing environmental pressure to the earth. One of the popular approaches is to reduce, reuse and recycle. In this case paper industry face a unique situation where in one side there is a shortage of fiber sources along with increasing pressure on forest utilization which increase the cost of fiber while on the other side more waste paper generated means more potential sources of secondary fiber available. The objective of the research is to figure out the effects of sludge addition in used aseptic beverage packaging utilization in samson kraft manufacturing and the effect of sludge fractionation prior to beating in improving physical properties also investigated. Sludge addition level is 5%, 10% and 15% each with different treatment, treated and untreated with fractionation. This research resulting in a significant decrease of burst index and Cobb value. However, all tested parameter showed a decreasing trend along with increasing sludge addition in the furnish. Fractionation of sludge gave significant effect in the burst index, tear index and tensile index of the test sheets. There are 5.81% and 10% increment in burst index and tensile index respectively, while tear index decreased by 10.45% when the sludge underwent fractionation prior to beating. Sheet from furnish configuration up to 90% of beverage aseptic packaging recycled fiber and 10% of fractionation treated sludge able to surpassed the average samson kraft burst index available on Indonesian market. The same configuration also met the standard of light weight liner set by European Containerboard Organization. Generally, the average value of the test for burst index is 1.84 kPa.m2/g; tensile index is 26.33 Nm/g; tear index is 4.83 mN.m2/gr; and Cobb value of 110.36 g/m
