In the new expansion of our production capacity we once again added anMPR to the twin screw extruder,” says Sky-Light owner Søren Larsen. “The growth in output through the increase of the bulk density of PET flakes and flat sheet waste and the stable IV value are more than convincing from the point of view of an entrepreneur.” Sky-Light is a specialist for individual packaging solutions. The Dan- ish company produces several hundred million snap-on lids, cups, inserts, blister and transport trays for customers in the food, electronics and pharmaceutical in- dustry. The technical and economical improve- ments in the course of the relaunch in- clude being able to reduce the connected load by over 30 per cent while maintain- ing output. “The calculable operating The MPR from EREMA allows the decontamination, drying, dedusting and crystallisation of different PET input materials already prior to extrusion.

The Italian company – as part of the Aliplast Group – makes thermoforming sheet from post-consumer PET which is then used to make thermoforming contain- ers for the food industry, for example. Besides twoMPRs the Aliplast Group also has VACUREMA systems from EREMA to produce food contact grade PET recy- clates. Additionally, the relaunch came with a higher degree of automation and improved ease of maintenance with the vacuum system. The process water tank has been replaced by a utility-free vacuum pump which reduces operating costs. The compactness of the system has in general been reworked, which can be seen in a 20 per cent saving in space. Ideal addition for existing extrusion On the one hand the relaunch of the MPR last year aroused the interest of new customers and, on the other hand, is confirmation formany existing custom-
