Amut and Erema Hold Open House together
Demonstration Plant Launch
Amut spa, Novara, Italy and Erema Engineering Recycling Maschinen und Anlagen Ges.m.b.H., Ansfelden, Austria, are holding an Open House to present a "Bottle to Packaging" process and show that the desired closed material loop in the PET sector is already reality. The post-consumer flakes are processed in the new demonstration facility – a direct combination of Vacurema technology and the Amut Inline Sheet plant – in a single process to make food contact grade thermoforming sheet. Thanks to the direct combination of recycling and production technology there is no longer any excess process stage. This is because the melt goes straight from the Vacurema to the Amut plant without the detour of pelletizing.
The rPET sheet will be used to make thermoformed trays for the food sector at the Amut booth during the Plast Milan show. The demonstration facility in Novara will continue to be available for customer trials also after the Plast Milan show.
100 Percent Food Contact Approval
The post-consumer PET material is already decontaminated and pre-dried prior to extrusion in the vacuum reactor of the Vacurema Basic, with a throughput of up to 1,000 kg per hour. The newly developed Erema PET Laserfilter processes input material with a degree of contamination of over 1 % without any difficulty and discharges the filtered particles continuously. Thanks to its unique pressure consistency this filter system is particularly suitable for inline production. Despite varying moisture, IV values and bulk densities in the input material, the melt has a constantly stable IV value and color. Additionally, the process stands out through what is only a marginal IV drop. The melt then goes directly into the Amut Inline Sheet plant where it is processed into thermoforming sheet.
The integrated online viscometer shows the user the actual viscosity of the melt. High-stiffness cooling rolls guarantee precise material planarity. Another boost in sheet quality comes from the fully integrated inline thickness gauge control. The hot lamination system represents an additional production benefit and is particularly suitable for sensitive barrier film thanks to the adjustable contact point. The wet coating at the end makes for an antistatic and anti-blocking solution. The monolayer thermoforming sheet produced from pure rPET is not only 100 % food contact compliant, it also fulfills the FDA regulations and EFSA guidelines.
