Leybold presents its innovative vacuum portfolio at the international trade fair for the meat industry IFFA in Frankfurt am Main from 04 to 09 May 2019 in hall 11, booth A41. The new Novadry vacuum pump series will be the focus of the presentation. The completely newly developed, oil-free screw vacuum pump ensures significantly greater safety and efficiency in food and packaging processes.

Vacuum as a key technology

The demands placed by manufacturers and consumers on the quality, shelf life and resource efficiency of food and packaging processes are constantly increasing. This applies even more to such perishable products as for example meat or fish. Vacuum is considered as an enabling technology, contributing significantly to optimizing these processes. Therefore, Leybold developed the innovative Novadry, a new 100% oil-free, air-cooled pump, which will be launched at the IFFA.

No oil, less effort

“Many users in meat processing and packaging cannot actually tolerate vacuum pumps emitting oil,” stresses product manager Niels Gorrebeeck. Novadry prevents such contaminations. That is why Leybold designed a 100% dry pump following hygienic criteria. This increases safety in applications such as tumbling, filling, vacuum packaging and thermoforming. An additional advantage of oil-free vacuum pumps is the lower cost of ownership, as less maintenance and spare part changes are required.

In addition to the oil-free screw principle, Leybold has transferred proven components and principles from other vacuum pump series to the Novadry, including the bearing structure and the belt drive, which synchronizes the rotors in the Novadry.

Broad range of applications

The Novadry also stands out due to its long uptime and robustness. Some competitor products lose their end-pressure or reduce pumping-speed due to wear of the inner coating, for example. The Novadry, however, achieves its performance over the entire pressure range and life cycle. This makes it ideal for simple applications, which emit low amounts of humidity, such as packaging of cold products. Moreover, the pump is also perfectly suited for more demanding processes with large amounts of water vapour, for example when hot meals with temperatures of up to 95°C have to be quickly cooled down by evaporative cooling. “In addition to the air/steam mixture coming from the process, the Novadry screw vacuum pump can also handle the anticipated contamination inside the gas flow very well. These are for example organic acids, spices, vinegar or other residues,” summarizes Pierre Lantheaume, Business Development Manager Food & Packaging at Leybold.

Proven in real life

Novadry has successfully passed many qualifying field endurance tests in a wide range of food applications – tumbling, tray sealing and thermoforming. In all applications, it shows very good performance, the users reached fastest cycle times and low final pressure.

Forward-looking pump

Leybold have succeeded in developing a forward-looking product which has the potential to set a new standard for the food processing and packaging markets. This is due not only to the absence of oil, but also to the Novadry’s noise behaviour, the robust design and the low life-time costs.

Multivac New dimension in pack labelling performance
Picture: Multivac

At Fachpack 2019 Multivac will be presenting a new generation of cross web labellers. In addition to improved performance and operating reliability, one of the features of the new models compared to the previous labelling solutions are their lower life cycle costs. The use of state-of-the-art communication standards such as IO-link and EtherCAT ensures that they are equipped for the future. This enables additional sensor systems for example to be used, such as those for labelling inspection or predictive maintenance.

The new cross web labellers are process-controlled. Individual movements are overlaid as much as possible, so that an optimised and therefore significantly faster labelling process is achieved. Servo drives on all axes, as well as the virtually continuous operation of the longitudinal shift unit, ensure that the cycle output is increased still further.

Higher performance, compact design

The new labellers have been fitted with the latest generation of label dispensers, which also contribute to a higher cycle output thanks to their sophisticated servo motor technology. The use of servo drives also offers the benefit, that no reference runs have to be performed before the labelling operation is begun – and this means that set-up and conversion times are reduced, so that the labellers are operational more rapidly.

The robust construction of the new machine generation also makes a contribution to increasing the cycle output. The axis of the longitudinal shift unit is for example designed with even greater torsional rigidity than previously. The machines operate with significantly less vibration, and their travel range can be completed in a shorter time. The simplified construction with its fewer number of deflection rollers accelerates label roll change and makes it even easier, so that downtime is also reduced. In addition to these benefits, the more compact design also means a reduction in space requirement.

Greater ease of operation, high level of efficiency

The new machine generation from Multivac also sets the benchmark in the market for its ease of operation. Menu guidance has been optimised and equipped with an integrated wizard function. The system only needs the required number of cycles to be entered – after that all the relevant speed and acceleration parameters are adjusted automatically. The Quick Control panel is also integrated in the labeller housing, so that the operator has less distance to cover.

Removal of the vacuum box hood and access to the pusher plate set is quick and easy, and this can be performed without any tools. The necessary service work can be carried out in a user-friendly way and above all very rapidly. The reduction in time and effort increases efficiency and makes itself felt immediately in the life cycle costs.

Maximum reliability, high level of availability

Particular importance was attached to machine reliability, especially in view of the high cycle speeds. The constant monitoring of travel speeds and torque ensures that the highest level of process and operating reliability is achieved even at maximum output.

Thanks to targeted minimisation of potential faults, Multivac has significantly increased the reliability and availability of the labelling system. The reduction in moving parts and an improvement in the cable feed also make a significant contribution.

Equipped for the future

The new cross web labellers are already designed for the demands of tomorrow. State-of-the-art communication standards such as IO-link and EtherCAT enable the machines to be equipped with the latest sensor technology. Additional solutions for labelling inspection can also be easily retrofitted, since the corresponding interfaces are already integrated. And last but not least, the labellers are designed for predictive maintenance.

A state-of-the-art environmental lifecycle assessment (LCA) has confirmed that single-use beverage cartons compare favourably with reusable glass bottles – and outperform single-use PET bottles – across the fresh milk, juice and UHT milk market segments.

The results of the critically reviewed LCA study are based on an in-depth analysis of the German beverage packaging market, with expert review and oversight by the German Federal Environment Agency (UBA). The conclusions are globally relevant and support the findings of previous critically reviewed LCAs that beverage cartons offer environmental advantages to alternative forms of packaging for liquid dairy and juices.

SIG Chief Executive Officer Rolf Stangl commented: “The latest LCA confirms once again that beverage cartons are the preferred environmental choice for milk and juice packaging. The high proportion of renewable content in single-use beverage cartons puts them on a par even with glass bottles that can be reused multiple times. These results are based on standard beverage cartons that are around 75% renewable and SIG already offers customers innovative products that are linked to up to 100% renewable content.”

Rigorous assessments for informed decision-making

SIG is a member of the German Beverage Carton Association FKN, which commissioned the LCA study to support informed decisions on packaging by food producers, consumers and policymakers based on a robust scientific comparison of environmental impact.

The LCA was conducted by the Institute for Energy and Environmental Research (IFEU) in accordance with the recognised ISO 14040/44 international standards. It is the first study to meet the new requirements stipulated by the German Federal Environment Agency (UBA) for beverage packaging life cycle assessments in Germany.

Benedikt Kauertz, Scientific Director at IFEU said: “IFEU supported the UBA in developing its minimum requirements for LCAs for beverage packaging. The study commissioned by FKN is the first to implement these requirements and adopt such a robust approach. The results show that beverage cartons for milk and juice are advantageous compared with single use PET bottles. For milk, beverage cartons are even better than the reference system, reusable glass bottles, and for juices beverage cartons perform on a par with the reference system. For UHT milk, where no reusable packaging option is available, beverage cartons perform better than the single-use PET bottle alternative.”

Environmental advantages of cartons confirmed

Reusable packaging options, such as glass bottles that are returned to food or beverage producers to be used again, are often assumed to be the best option for the environment. That is why reusable options, where available for a particular market, are used as the reference system for comparison.

Based on an in-depth analysis of all three market segments – fresh milk, juices and UHT milk – the beverage carton performs at least as well, or in the case of fresh milk, even better than reusable glass bottles. The latest study also confirms that both beverage cartons and reusable glass bottles outperform PET bottles for fresh milk, juice and UHT milk. Where no re-usable system is installed, beverage cartons are clearly advantageous.

Cartons perform significantly better than the alternatives on climate change – the category given highest ecological priority by the UBA. The climate impact results for cartons are 78% lower than reusable glass bottles for fresh milk, 37% lower than reusable glass bottles for fruit juices and 71% lower than PET bottles for UHT milk (for which no reusable options are available).

The high proportion of renewable material used to make beverage cartons – 75% on average – contributes to their strong environmental performance, together with their highly efficient design which reduces impacts from transport and distribution. The favourable results are underpinned by the industry’s commitment to sourcing from responsibly-managed forests.

LCAs support responsible product innovation

LCA is fundamental to SIG’s robust approach to product responsibility and informs the focus of the company’s product innovation. This latest study confirms the important contribution that renewable materials make to the excellent environmental performance of beverage cartons and SIG is working to increase the proportion of renewable content in its packs. SIG’s Eco Plus pack is 82% renewable and its Signature Pack 100 is the only aseptic beverage carton to be linked to 100% forest-based materials, using an innovative mass balance approach. These innovations are part of SIG’s commitment to go Way Beyond Good by putting more into society and the environment than it takes out.

After more than 18 years as CEO of the Multivac Group, Hans-Joachim Boekstegers will hand over the business on 1 January 2020 to his director colleagues, Christian Traumann and Guido Spix, and bow out of the company. Mr Traumann and Mr Spix will manage the company jointly in future.

Hans-Joachim Boekstegers joined the Multivac Group as CEO on 1 April 2001 and has since played a determining role in driving forward the successful development of the company. Mr Boekstegers was responsible in particular for the systematic expansion of the product portfolio and Multivac’s sales and service network. With 85 of its own subsidiaries, Multivac is today one of the leading manufacturers worldwide of packaging and processing solutions. During this time the company’s turnover was more than quadrupled, reaching some 1.1 billion euros at the end of 2018, and the number of employees rose from 1,600 to around 5,900.

With effect from 1 January 2020 Christian Traumann and Guido Spix will take up dual leadership of the Multivac Group. Mr Traumann will assume responsibility for Sales and Finance, while Mr Spix will become responsible for Technology and Production.

Christian Traumann had been Commercial Head of the Multivac Group since the beginning of 2002, before being appointed as Director and CFO for the Group in August 2008. Guido Spix joined the company as Director in March 2009 and has since assumed the position of CTO/COO.

In order to ensure that there is continuity in Multivac’s strategic direction, the course is already being set with an extended planning phase for the transfer of responsibilities to Mr Boekstegers’s successors. Mr Boekstegers will continue until the end of the year to guide Multivac’s destiny as usual, and he will remain on friendly terms with the company after this period.
