Extrusion International 5-2017

23 Extrusion International 5/2017 data and to operate all connected controls up to device level. All motan controls with communication capability can be connected. Batch tracking is therefore continu- ously possible. Success due to many years of proven partnership Finally, in his résumé of the project process, Helmut Reck- ziegel sums up the main criterion for the stable produc- tion after only a short start up phase: “In view of the in- troduction to a new dimension of mass production, it was important for us to keep the technical risk at a small, man- ageable level. It is not least for this reason, therefore, that we decided to continue our long standing, proven part- nerships. We have been working with Luger, the systems technology partner of motan, for more than 40 years al- ready. We knew from similar machine projects in the past that the motan components would not call into question the availability of the complete system of 90 per cent re- quired by us around the clock. Likewise, we assumed that the necessary dosing accuracy and the full integration of all setting and performance specifications would also be given in our “big data concept” for the logging of quality data.” (Fig.8) Autor: TECHNOKOMM, Reinhard Bauer ><KD Ͳ'ŵď, tĂƐƐĞƌƚƵƌŵƐƚƌĂƘĞ Ϯϰ ϲϲϵϱϰ WŝƌŵĂƐĞŶƐ dĞůĞĨŽŶ нϰϵ ;ϬͿ ϲϯ ϯϭͬϳϮ ϱϵ ϰϭ dĞůĞĨĂdž нϰϵ ;ϬͿ ϲϯ ϯϭͬϳϮ ϱϵ ϰϮ ŝŶĨŽΛĂůŬŽŵĂ͘ĚĞ ǁǁǁ͘ĂůŬŽŵĂ͘ĚĞ dŚĞ E t džƚƌƵƐŝŽŶ >ŝŶĞ motan-colortronic gmbh www.motan-colortronic.com Info box: Multi layer foil coffee portion capsules What requirements? Coffee portion capsules made of foils must form a barrier against the ingress of steam, atmospheric oxygen and other unwanted substances as well as against the effects of UV radiation. The barrier must also protect against the escape of constituents such as aromas and moisture. At the same time, the foil cups can also provide protection against defined mechanical stresses during transport and storage. Which foil structure? A 7 layer compound foil is used for the coffee capsules. Its central layer consists of EVOH (ethylene vinyl alcohol co polymer). It forms the oxygen barrier and is embedded on both sides via adhesion promoter layers of recycling material (punching waste). Coloured polypropylene layers (homo polymer and co polymer) are additionally applied as cover layers. Graphic: Greiner Packaging
