South Korea’s Ssangyong Cement Industrial Co. Ltd. enlisted its packaging supplier to produce an 88-lb. (40 kg) cement bag equal to rough handling en route to Antarctica research stations. Taemyung Industrial Co. Ltd. turned to two-ply Mondi Kraft Advantage sack, exhibiting what Vienna-based manufacturer Mondi Group notes is high tensile energy absorption and porosity. The product’s capacity to replace three-ply alternatives nets material savings exceeding 25 percent.
“These two-ply bags are the strongest in the marketplace, which means reduced breakages and more efficient, dust-free filling on the rotopacker as bags no longer require perforation,” says Mondi Packaging Paper Sales, Asia Managing Director Gerry Gosen. In recent years, he adds, the company has worked with cement producers to develop economical, durable bags, including the 88- and 110-lb. (50-kg) Kraft Advantage offerings.
Packaged cement for Antarctica research station construction, expansion and maintenance is moved, carried and dropped throughout the supply chain up to 10 times; bags must survive multiple drops from packers, trucks, pallets and warehouse stacks with heights up to 12 feet. The coldest, windiest, and driest place on earth, Antarctica has a desert climate, with near-zero humidity and average annual temperature of -47°C. — Mondi Paper Sales GmbH, Austria, www.mondigroup.com
