      Buying time during cleaning

      The performance variant uses hot caustic for machine surface disinfection and reliably sterilises the product channels with steam. This process guarantees microbiologically safe filling in the fastest cleaning and sterilisation times.

      The benefits

      • Timespan from last to first bottle:  
        • only 90 minutes – including cleaning and sterilisation
        • Saving a full hour compared to other systems
      • Only 30 minutes intermediate sterilisation after manual interventions in the block
      • Handling parts change-over at the blow moulder:
        • Without intervention in the sterile area
        • Therefore no intermediate sterilisation required

      The key components

      The key components

      Prejet Preform rotary rinser

      Compact one-starwheel concept at ground level

      Method of operation:

      • Immersion of the rinser lances in the preforms
      • Blowing out of the particles with pre-filtered andionised sterile air
      • Simultaneous to particle blow out: Extraction of themix of air and dirt 
      Cap sorting and inspection
      Media module

      Contifeed preform feed system

      • Thanks to hygienic design optimal for the Contipure Bloc P
      • Variants adjustable depending on the installation position

      Infrared oven 

      Servo-controlled oven of the Contiform standard series with efficient and pre-filtered preform air cooling system 

      Option: Tool-free quick-change of the protective plates of the oven heating mandrels

      Optimised in terms of energy:

      • Low dead spaces between the heaters 
      • Longer infrared radiators
      • Use of parabolic mirrors 

      Preform sterilisation module

      Contipure D preform sterilisation module

      • The module is between infrared oven and blowing module. 
      • Via nozzles, a targeted and directed feed of gaseous hydrogen peroxide (H₂O₂). 
      • This provides overflow and thus results in a simultaneous internal and external preform sterilisation.

      Blowing module

      • Improved hygiene standard
      • The air used for stretch-blow moulding the PET bottles is filtered beforehand using a pre-filter unit with autoclaveable filters.
      • A fine dust filter is also installed on the heating module to ensure that dirt particles such as coal dust, pollen or plant spores are filtered from the ambient air.
      Central ventilation technology

      CapAsept D cap sterilisation module

      • Caps are blown out with ionised air right in front of the unit.
      • Sterilisation by means of gaseous H₂O₂
      • No back-up pressure acting on the caps – no deformation
      • Clocked feed of the caps on demand: No bottle – no cap

      Aseptic capper

      • Every capping head has its own separate servo drive. 
      • A transfer tunnel separates the sterile area from the outside area. 
      • The proper technique for every cap – overcaps with round bottle possible!

      Aseptic filler

      • The appropriate filling valve for the most wide range of products – still and carbonated
      • It is also suitable for beverages with (fruit) pieces of a size of up to 10 x 10 x 10 millimetres
      Valve manifold

      Benefits to you

      Triple protection

      The all-round treatment with gaseous H2O2 sterilises the entire preform surface at once: Inside, outside and in the neck area.

      Gentle preform treatment

      The sterilisation of the preforms hardly leaves any residues: This is because the surface enlarges by many times and the residues of the sterilisation medium are diluted accordingly.

      Flexible production

      The optional automation package allows change-overs to be performed on the entire block in under 20 minutes – including the emptying and starting up of the machines. This means that you gain an additional two hours of production time with each change-over – and operators have their hands free to perform other tasks.

      Fully-automatic change-over

      Handling parts change-over at the filler and the capper can be performed up to a defined output without any manual interference.

      High availability 

      The complete block production can run for up to 120 hours at a time – and only a short 90 minute sterilisation break is required before it is back in action and ready for the next round. Intermediate cleaning after manual interventions also only takes 30 minutes.

      Pinpoint production

      Filling to the last drop: The system uses the remaining product quantity in order to calculate exactly how many more PET containers and caps are still to be sterilised.

      Material properties, processability, food grade quality: you can find all kinds of interesting facts about the use of recycled PET in our free white paper.

      The facts:
      everything you need to know about rPET

      Everything you need for PET: the closed plastics cycle under one roof

      Can plastic packages be sustainable? Yes, they can, if the process for producing them is resource-economical and if they are kept in a closed cycle. You can achieve both of this with technology from Krones and the services it provides. Starting with material-saving packaging design, then low-energy container production right through to recovery of used plastics: Krones offers PET bottles and other packages a chance for a sustainable, eco-compatible life-cycle – not only once, mind you, but again and again.

      In the preform production process, every tenth of a second in cycle time and every tenth of a gram in weight count. And there are plenty of potentials for meaningful savings. To exploit them, two things are necessary: firstly comprehensive knowledge of the properties and the behaviour exhibited by the various preform materials, and secondly a profound insight into the production processes involved – both into preform injection-moulding and into the salient aspects governing subsequent container stretch blow-moulding. You will find both of these in the Krones Group.

      MHT AG, a company that has specialised in making PET tools for producing preforms, has been part of the Krones family since 2018. Its performatively excellent high-tech injection-moulding tools

      • image all preform designs and threads in common use;
      • are suitable for almost all machine platforms known on the market;
      • are based on an innovative hot-runner technology developed in-house.

      Secondary packaging

      When it comes to reducing the use of materials, we mostly think of the beverages containers first. But if we take a closer look, we can see that there is also plenty of savings potential with secondary packagings.

      Doing completely without plastics

      It is also possible without film: LitePac Top is an innovative secondary packaging from our own development. Instead of shrink film, it keeps cans and PET containers in shape with an environmentally friendly cardboard clip - and thus meets the pulse of the times in terms of sustainability and resource conservation.

      Packaging your containers without film

      The difference to many other alternative packaging types: LitePac Top can already be produced on an industrial scale today - and is thus ready for immediate use on the market. This is because the Krones Varioline can handle the most diverse types of secondary and tertiary packaging, including LitePac Top. 

      Discover the many possibilities offered by the Krones Varioline

      Consuming less plastic 

      You don't always need a new type of packaging: There's also still plenty of material to be saved in existing pack types. 

      Optimising the machines 

      The Variopac Pro packaging machine offers several options for noticeably reducing shrink-film consumption - by upgrading to reduce:

      • the film thickness by up to 25 μm.
      • the lateral film projection.
      • the film residue on the film reel.

      Optimising the packaging material

      A service for all those who use shrink films optimally:  In a film analysis, we examine and evaluate the films you have selected based on all of the relevant parameters. The results will be sent to you in a conclusive report with clear evaluation graphics – which provides you with an ideal and, above all, objective basis for making decisions during film selection. Whether material thickness, overlap or overhangs: even when it comes to recycling films, we will gladly accompany you to the limits of what is technically feasible. Benefits to you: More sustainability with lower costs!

      Buy, drink – and that’s it? Not by a long way! From a consumer’s viewpoint, the lifespan of a PET bottle may seem short. But the bottles themselves know better. After all, they are made of a material with outstanding recycling properties. And that talent can be utilised again and again.

      So it is all the more surprising that billions of PET bottles per year are still not being re-used – meaning a gigantic raw-material source is simply lying fallow. The Ellen MacArthur Foundation estimates the value of plastic waste unused today at 80 to 120 billion dollars a year. An enormous potential just waiting to be tapped. And that’s not all: recycling plants turn waste into new products – and can thus make a substantial contribution towards reducing the global littering problem.

      The MetaPure recycling systems

      • … recycle PET containers
        • into flakes (on request with direct downstream processing into new products).
        • in different material qualities.
        • right up to food-grade PET in line with FDA, EFSA and other certificates.
      • … recycle containers made of polyolefins (PO)
        • into flakes.
        • in the upcycling approach for high-quality re-use.
      • … are available as individual machines – or in the shape of a complete single-sourced recycling plant.
