It is well known that there is no machine more unproductive than a machine stopped. Comexi have this lesson very well learned. That is why the ergonomics of its laminators are among the market leaders with the lowest downtimes. Its models are designed to facilitate the work and the operability and, at the same time, increase the productivity reducing to the minimum expression the change and maintenance times. Specifically, the Comexi lamination line was a pioneer in the detection of this tendency within the market and the group has established itself as one of the suppliers with the highest benefits in this regard.
But this is not enough. The flexible packaging market is becoming professionalized at high speed. A few years ago this trend was only evident in some large international groups but today it is already a consolidated reality in medium and family businesses. Currently, customers are already thinking about TCO (Total Cost of Ownership), giving more importance to the operating cost than the initial investment cost. As a result, the actual speed of the lamination process becomes a key and a fundamental parameter for the customers.
In this sense, Comexi has recently increased the maximum speeds of its solventless laminator. In the case of the Comexi SL3 laminator, it has gone from 350 to 400 m/min and in the Comexi SL2 from 450 to 500 m/min. But it must be clear that the mechanical speed and the speed of work are not synonymous. Is in this aspect where many of its specific characteristics - part of its value proposition- allow to increase the performance and benefits of our machines. The mechanical stopper, the 3-roller nip, the control of the tension, the robustness... Today more than ever it is necessary to increase the working speeds. It is necessary to add all the necessary elements so lamination can be done at maximum speed and, in order to succeed, it is essential to work side by side with customers.
That is why; Comexi has carried out an exhaustive speed study in both lamination and coating for different structures and materials. The group currently have a set of important data that are very useful for its customers. Thanks to these investigations, it has been possible to verify, once again, that the laminator is only one of the many elements that takes part in the lamination process.
For example, one of the most typical and at the same time complex structures of materials is PET with aluminium. Thanks to its mechanical stopper on the pressing roller of the applicator, Comexi’s laminators can apply the adhesive directly on the aluminium, taking full advantage of the best wettability of this material. Combined with adhesives with low CO2 emissions and the correct ratio of temperature and tensions, Comexi’s laminating machines can achieve high processing speeds. A joint work between machine, adhesive and operator.
We can say that a successful lamination depends on the large extent on both internal and external factors of the process. Very critical factors such as the quality of the material, the type of adhesive used, the skills of the technicians and, of course, customer’s degree of exigency. Hence the importance of the tests and trials carried out in Comexi and Manel Xifra Boada Technological Centre (Comexi CTec) facilities, a unique space where - with the collaboration of partners and suppliers – the group can provide a high added value service.
Each year, the Comexi CTec carries out about twenty courses, five of them dedicated to the field of lamination. The centre stands out as the reference institution in training, innovation and consultancy within the sector and the flexible packaging industry. Throughout 2016, there were 63 demonstrations with laminators, a figure significantly higher than the previous year. Above all, it should be noted that these demonstrations are increasingly personalized, tailored to the needs of each client. Specifically this year, an advanced technical rolling course in German has been carried out for the first time, which has achieved great success and good ratings by attendees and participating companies in the sector, thus satisfying a clear demand in the flexible packaging market.
At the same time, the CTec also offers developments with adhesive manufacturers, technical advice to clients and ‘In hand’ project consults, as well as customized machine operating trainings - both at CTec facilities and customer plants - to improve the knowledge of companies.
