Kuhne Anlagenbau GmbH is presenting its solutions for the food industry for the first time at K 2022. Triple bubble blown film technology can be used to produce thermoforming films with reduced thickness, thereby saving costs and material.\u00a0<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Without compromising on performance characteristics, the simultaneously biaxially stretched thermoforming films in the triple-bubble process with 80 to 120 \u00b5m only about half as thick as the classic<\/strong>The moulding foils used in this application. A maximum thermoforming ratio of 1:10 can be achieved. This means a reduction in material consumption and therefore the associated greenhouse gas emissions by around 50 per cent.<\/p>

Thanks to optimised cooling rates, the large-scale systems enable throughputs of up to 2,000 kg\/h and annual production rates of up to more than 15,000 t\/a. Their productivity and profitability can therefore match or even exceed that of cast film lines. In further processing storage is also reduced, and the significantly lower energy consumption during thermoforming enables a further reduction in CO2<\/sub>-footprint<\/strong> with good machinability at the same time. For the manufacturer and distributor, the reduced-thickness films reduce the fees incurred as part of extended producer responsibility (EPR) and support fulfilment of the CEFLEX (Circular Economy for Flexible Packaging) sustainability guidelines formulated by the industry.<\/p>

Shelf life-extending vacuum packaging for the transport and storage of large pieces of ham, meat or cheese is one of the typical applications of such multi-layer films. They are usually based on PA, EVOH and PE and combine high transparency with good suitability for thermoforming and high puncture resistance<\/strong>.<\/p>

The perfection now achieved by Kuhne Anlagenbau in the triple bubble process developed in-house back in 1996 now gives the processor access to the Combination of low film thicknesses with the high throughputs that can only be achieved with large machines<\/strong>. The traditional economic advantages of cast film over blown film are therefore a thing of the past in this area.<\/p>
