Amut and Erema are holding an Open House to present a sophisticated “Bottle to Packaging” process from 28 to 31 May 2018. Washed post-consumer PET bottle flakes will be recycled live at the AMUT headquarters in Novara, Italy, to make food contact grade thermoforming sheet in a direct process. This rPET sheet will be used at the Plast Milan exhibition – which is being held at the same time – to make thermoformed trays for the food sector. Interested producers will be able to process their own input material on the demonstration system in future to make plastic rolls. They can then test the samples later in their own thermoforming production to check the quality.
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. 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 pelletising.
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 1,000kg/h. 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 colour. 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.
A free shuttle service between the trade fair in Milan and the AMUT headquarters in Novara will be available for attendees. The demonstration facility in Novara will continue to be available for customer trials also after the Plast Milan show.
