Mondi at South Pole

 

After the successful implementation of Mondi's Advantage Select sack kraft paper in 2-ply cement bag solutions in Asia and Africa, Mondi Kraft Paper is now up for a new challenge—the South Pole/Antarctica.


Antarctica is the coldest, windiest, and driest place on earth. It has a desert climate, air humidity near zero, and it almost never receives rain. The average annual temperature is -47°C, with lowest temperatures possible at -89.2°C. In short, it is one of the most inhospitable places on earth.


The prime focus of life in Antarctica is scientific research. The population is transient, consisting of scientists and networks that support them, living in research stations across the continent. Cement is needed in the construction, maintenance and expansion of these research stations.


When Taemyung Industrial Co. Ltd. was requested to produce a 40 kg cement bag for Ssangyong Cement Industrial Co. Ltd. to be delivered to the South Pole/Antarctica, the consistent performance of the bag was imperative. In fact, a cement bag has to contend with a wide range of temperatures and climatic challenges. In addition, the bag is handled, moved, carried and dropped throughout the supply chain up to 10 times, needing to survive multiple drops from packers, trucks, pallets and warehouse stacks with heights ranging from 1 up to 3 meters. 


Taemyung Industrial already had extensive experience utilising Mondi's sack kraft paper grade Advantage Select in the South Korean cement industry. So according to Mr Gyung-Min Kwon, Director of Taemyung, "the only choice was Mondi's Advantage sack kraft paper."


2-ply cement bag solutions using Mondi Advantage Select have superior tensile energy absorption (TEA) combined with high porosity. On top the replacement of 3-ply constructions has resulted in lighter bags with material savings of over 25 percent. Gerry Gosen, managing director Mondi Packaging Paper Sales Asia, says: "These 2-ply bags are the strongest in the marketplace which means two things for our customers: reduced breakages, and more efficient dust free filling on the rotopacker as bags no longer require perforation." 


With companies worldwide looking for cost savings along with innovations to grow business, Mondi Kraft Paper works closely with key stakeholders in the cement industry to provide such solutions. 50 kg and 40 kg bagged cement* has become the norm throughout much of Asia. Over recent years Mondi has co-operated with major cement organisations to develop cement bags that are superior both cost- and functionally-wise. 


* Typical are currently 50 kg, 2-ply, 80 gsm and 40 kg, 2-ply, 70 gsm bag solutions.
