remain under pressure and as a result it is more important than ever for corrugators to optimise all aspects of their plant’s operation. One element that plays a significant role in this process, but which is often overlooked, is lubricant selection. Choosing high performance oils and greases can provide important operational advantages. We spoke to Inken Reuser, EAME offer advisor at

Do corrugators need to pay specific attention to their lubricant selections? Absolutely. Selecting and applying the most suitable oils and greases can help to: • Reduce a plant’s energy bills • Extend oil drain intervals • Protect equipment and extend life


• Minimise unexpected downtime and extend service periods • Reduce potential oil leakage


Amongst the many aspects of manufacturing corrugated paper products, lubrication systems in the equipment are easily overlooked but have a key role to play. PPL reports

• Provide problem-free operation in food and beverage processing plants


These improvements to equipment reliability can help to reduce maintenance-related costs and also increase plant safety by reducing human-machine interaction (HMI). To achieve these goals, it is important that corrugators use high performance lubricants, especially for bearings on heated rollers as the high temperatures can adversely affect the performance of oils and greases.


What factors affect a corrugator’s choice of lubricant? A typical corrugating machine offers a number of lubricant challenges including high temperatures (up to 200 deg C) and contact with steam, which is used during the forming process. Persistent exposure to elevated temperatures can cause a lubricant to thermally degrade, exposing machinery to increased wear. It is therefore essential to ensure the selection of lubricants with appropriate levels of thermal
