Over the past 12 months, Mondi has worked with South African cement producers to encourage a switch from 3-ply to 2-ply bags.
In cooperation with sack converter customers, Mondi has worked to demonstrate the advantages of high porous 2-ply and has provided knowhow on changing the cement sack construction. The South African cement industry uses more than 160 million sacks each year and had previously used 3-ply semi-extensible perforated sacks. In product trials held last year, Mondi proved that bags made of 2-ply kraft paper were better suited to the task, given the challenging nature of cement packing and handling in South Africa.
Nicholas John, Afripack Sacks General Manager said, "We were convinced by the better quality and efficiency of switching to high porous 2 ply. What really made it work was great support from Mondi on implementing the change."
Two-ply bags help sack converter companies make gains in cost and efficiency, and reduce bag breakages and dust spillages for cement manufacturers.
