| Abstract | Recently, there has been a trend in decreasing the basis weight of medium weight coated paper. Because the paper market becomes competitive, it drives companies to keep the market share relying on reducing the basis weight. Taking into account this view point , the effect of basis weight reduction on sheet properties is considered to be evaluated. Softwood ( SW ) frayed fiber and filler share are used to maintain strength and opacity of paper . The basis weight is varied from 70 gsm to 55 gsm. From the experimental results , it is found that in order to maintain acceptable strength and opacity , the basis weight can be decreased from 70 gsm to 60 gsm . Further, filler retention above 25% decreases the paper strength gradually al though the opacity of paper increase s . A 10% softwood frayed fiber cannot maintain strength if the filler retention is 30%. However, employing a combination of SW frayed fiber of 10% and filler share of 25% , the strength and opacity can be retained after reducing basis weight as much as 10 gsm i.e., from 70 gsm to 60 gsm . |
